  • Jensen Mathews

    Hi Max,

    Great website dude! I have to ask what is the best ROM for a galaxy s2 I am a newb my Galaxy s2 3 days old. My Galaxy s2 I think is the international version because its from the UK. So I am looking for a ROM that improves battery life and performance and has no bloatware…can’t get rid of the bloatware as easily as in your AT&T vids as there is no option to uninstall.

    Also should look out for anything specific when installing a ROM for the phone like the current kernel and OS version I have heard in other videos that modem version is important…any advise. – J

  • TMN

    Hey 🙂
    Thanks for this awesome website on rooting. Im new to this and before I did root my phone, Is there a way to unroot it? I couldn’t really find anything on unrooting the international version galaxy s ii on this website.
    And also, when I do root it, will I lose any/all data, such as contacts/messages/video/music/documents/applications?
    And also the same for installing the ROMs. Would I lose any/all data when I install a ROM, after I root the device?

  • Sickin

    Wondering if you could help me out. I have a new galaxy s 2, from us cellular the r760. I tried your root method and it does not work for my phone. I am new to development but doing what I can to learn what I can. Any chance you could help point me in the right direction to get started on figuring out how to root this thing.

  • Bankai

    Hi zedomax. See i had downloaded the latest resurrection rom v9.6 for samsung galaxy s2 i9100 and stored in my sd card. When i was in the recovery mode(the default one),there was an error and it couldnt install the rom.Then i installed clockworkmod recovery v4.0.0.2 through odin3 v1.83.After that my galaxy s2 started with a yellow triangle and automatically entered the recovery mode (clockworkmod recovery v4.0.0.2 one). I selected “wipe cache partition” and “wipe data/factory reset”. After that i selected “install zip from sdcard and i saw the options
    _apply /sdcard/
    _choose zip from sdcard
    _toggle signature verification
    -toggle script assets
    _ +++++Go Back+++++
    But I’m left with the statements
    E:Can’t mount /sdcard
    E:Can’t mount /sdcard/
    Nothing worked and when i selected “reboot system now” the galaxy s2 logo screen logo appeared with the yellow triangle and i was once again taken to recovery mode.Please help me because I’m helpless right now and I want to fix my phone as soon as possible

    • Bankai

      Hi Zedomax. I forgot to tell you something.In this situation i can go into both recovery and download mode.Please help me as soon as possible.

  • Subramanyam Mishra

    Could u please provide me the links for downloading nearest kernel insecure and secure kernel both

  • Igor Ossaille


    first of all thanks for all your hard work, your site is amazing.

    I rooted my Samsung galaxy s2 i9100 by your method last week and now Im trying to install the Clockworkmod, the thing is: when you tell us to run Odin3 1.85 it pops up that window but in my case its COM7 and not COM18, can I continue to do it?

  • Guijeta

    Hello Max,
    Currently i’m running the 2.3.4 version of Android and really want to try the new ICS ROMs, but none of the ROMs i’ve dowloaded worked. Do I have to update for a specifc Gingerbread version before being able to change for ICS?
    Also, after rooted my phone, Kernel version was modified to – 2.6.357-01045-g551a073-dirtycodeworkx@cyanogemmod#4″ , but I am not on Cyanogenmod ROM, is that correct?

    Thank you very much!

  • grant fleming

    Ok I have a problem. I flashed in my insecure kernel, and my computer stopped recognising my phone. So I shut my phone off. And instead of going off it showed the battery charging logo, followed my an empty battery, exclaimation mark and thermometre!. (My phone was not connected to anything at this point) and it wouldn’t turn back on. so I got it back into download mode, flashed in the original kernal, hey ho works connects to my pc however if I turn it off same thing, same logos and won’t switch on. So ever time my phone dies I need to reflash the kernal to get itto start upagain!

  • John

    Hey max, cungrats on the website, it really took me out of the dark…hehehehe.
    I was wondering….in your opinion, what´s the best ICS rom for i9100 that you´ve found so far?

    Big sheers, and keep up the good work.

  • Plays54

    Thinking of buying an unlocked Galaxy S2 while in the USA. But which one? I have seen one’s advertised with a designation SA-i9100 against the model number and also seen other designations like GT-i9100. The phone should be capable of operating in Europe and Australia and accepting any sim card when used in either country. As a previous Omnia (original) owner I had numerous problems getting the phone switched over from Dutch language base to English and the phone was forever having problems. I’m sure Samsungs have improved considerably since then but I don’t want to exoerience the same problems. Thanks

  • Jero Paulo T. Centeno

    Hello Max

    Good Day,

    i have a GT-I9100 with ICS XXLPQ and im a mac-pc user,
    do you have a tutorial for root and installing Resurrection Remix ICS PRO using Heimdall?
    i really want to try it. like you said it is the best ROM for the I9100 and i really want to flash it.


    More power.

  • Llewellyn

    Hey, I need a ICS rom with FULL USB HOST OTG support. is there anything out there that supports it or do I have to learn how to mod it myself? please im desperata

  • anikas

    Before I explain the pickle I’m in, I’d like to say your site is awesome. You provided me with a fool-proof way of rooting my phone, and exposing me to the full capabilities of my phone! 🙂

    So, I’ve been interested in the Resurection Remix ROM. I was running Clockwork v4.0 on my Galaxy S2 I-900M.
    Because this ROM req’s the ICS-based CWM, I flashed it using Odin without any issues.
    So now with the proper clockwork version, I though I was okay flashing Resurrection Remix.

    Problem 1 – I’m installing from zip, and clockwork aborts the installation. I get a message saying its “(bad)” and nothing goes through. (note: I wipped, and also wipped davlik right before trying to flash the .zip)

    Problem 2 – Because I’m on a different kernel now, any backups I try to use aren’t working on my phone. So I can’t turn the phone on. (I know I’m not bricked cause I can access clockwork! Phew.)

    Problem 3- I wanted to perhaps find another ROM, copy it into my SD and just flash using external storage buuut, I get a “can’t mount SD” message.

    In this case, do I format my SD card, then put the zip files back on it and try flashing again? How would I go about formatting my SD?

  • Harry Linssen

    Hey Max!
    I just installed the leaked I777 UCLC2 ROM, and e’thing appears to work OK, except for some out-of-place notifications.
    Now, of course, we are again standard AT&T/unrooted. Do I need a special ICS 4.0.3 compatible kernel, or can I use your old Zedomax kernel – in .tar format – as was used when rooting 2.3.4?
    All the UCLC2 compatible CF CWM kernels I can find are in a format that I don’t know how to flash…..

  • rob

    after installing a rom my phone now keeps on turning off randomly now. can anyone help. why does it keep doing it it was fine a week a go now its a couple of times a day

  • SuzukiKev

    Hi I’m totally new to the rooting, I really want to do it but not to sure on everything. I have just read that I can root it safely so that’s good news. But I have a few questions:

    1) If I root it using the safe way on here and I get to “superuser” will the phone still have everything I have on it now just I can access more things?

    2) What happens if I plug my phone into kies once rooted?

    3) Using the unrooting method can i get it back to Vodafone UK?

    Thanks in advance

    I have an I9100 Galaxy S2

  • Juan Carlos

    I have an AT&T SGS2. Actually I intented twice to install a Batista or Turbey ROM in my rooted phone but when start in Recovery mode the process is aborted due to a “verification process bla.bla.bla..” . XDA guys suggest, start process under Clockworkmod Recovery and activate “NO VERIFICATION…”.
    Someone feel the same problem?? As I investigate, CWMR is not and App. I saw inside Rom Manager, an option to work under this procedure.
    I someone feel as an expert, I full appreciatte its help..

  • jasjeet

    hello i have root my phone and installed rom remix v1.3 now i am not able to connect it to odin … plz help

  • Vasilis

    Hi max..You videos are absolutely life-saving..You explain in full detail everything! So, thank you for those…

    Can you please answer a question? I have recently flashed the resurrection pro 1.2 and i was wondering how i could update it in case there is a new version..I wouldn’t do it but i have noticed some problems i am having which could be bugs.

    If you like to check them out:
    1. The wifi direct is not working when i enable it!
    2. In Rom control when i choose the honeycomb lockscreen and lock the phone there is no ring for me to drag and unlock it!!!!! Thank god the notification bar can be used and again thank god i had zdbox in it so by clicking it it unlocked and got me to the desktop!!!
    3. Another thing i noticed is when receiving a call and the contact has a picture then the ring to answer or hang up is chopped off in the bottom of the screen..
    Have you noticed those as well??

    So, as i understand a rom can be updated if a new version is installed WITHOUT doing a factory reset… In this case the /data partition is not deleted so all user apps and settings are left intact..
    Or is there another way for me to do an update?
    I just dont want to set up my apps even thought contacts and all apps are downloaded automatically it is kind of frustrating for me to restore app settings and sms etc…

    Thanks in advance!


  • Wolfie

    Good Day Mr. Max

    I have run into a bit of a problem. I rooted my gs2 (Insane phone by the way) and I have gone trough a bunch of roms but then one day i noticed that my notification bar doesn’t slide all the way down it freezes at the last bit so I wen’t back to the stock rom. I have since flashed official rom via odin aswell as cmw but nothing fixes this bug oja when I want to dial a number an ring it the bottom part of the screen does’nt want to respond.

    So if you might know of a solution that would be great


  • NEW and easy galaxy s2 ROOTing method

    Hi Admin

    can you please put this on your website as it is much easier and safer

    “An easier way of rooting SGS2 (I9100) on ICS is by holding Vol up, Menu & Power buttons and flash Busybox installer then CWM through the update from zip from your SD card. Odin not needed.”

    Advantages over traditional method:
    this method WILL NOT increase your flash counter or give you an exclamation mark.
    it is all done on the phone
    it is much safer if you dont know how to use ODIN

  • Andy

    I currrently have the second latest nightly build of Cyanogenmod 9 and it is very stable in my opinion. No real problems i have run into yet. I was wondering if, when i download the latest version of the cyanogenmod 9 ROM, i will still need to do a factory reset and partition wipe, even when i am just going from an older version of CM9 to a newer version. Help would be greatly appreciated.

  • Dave B

    Hi ,just wanted to check if you had anything setup to unroot the Australian galaxy s2 its the 19100T, back to its original settings


  • Platypus

    Hi, I’m running stock ICS on my SGS2. But want 2 try out Lite’ning Rom v2.8.

    Rooted SGS2, installed CWM and Titaniumbackup. Backed up everything via CWM an Tbu and copied to PC.

    I want to be absolutely sure to be able to restore original ICS. If I install Lite’ning ROM and change kernel, will the restore option of CWM take me completly back to starting point with rooted stock ICS??? I don’t mind losing data, contacts or other. But being able to get back to stock ICS is crucial.

    Has anyone tried this procedure???

    Thanx in advance

    • Vasilis

      When you do a nandroid backup in CWM recovery then ALL partitions are backed up exactly the way they are (kernel, user data, system, cache).. This means that you can flash whatever rom kernel etc and then when you do a nandroid restore and your mobile will be exactly the way it was..It will be like you just restarted it..
      That’s why before any big changes it is necessary to do a nandroid backup!

      NOTE: If you flash a new radio for the device it will not be backed up, so when you restore you will have the new radio..

  • René


    • admin

      Just reflash the correct kernel in ODIN, that’s same as ODIN mode, for i9100G you will need a kernel specifically for i9100G, it’s the only version not supported on this site.

    I updated my phone to ICS via ur odin method, i previously used the odin method to root my gingerbread version too, now i find that the superuser is still there, should i delete it? What is the use of CWM? How do i update my S2 to ICS 4.0.5? I cant update my phone via the software update, it says theres no update, can u provide me with a manual update with instructions?My phone is now ICS 4.0.3, baseband version:I9100DXLP9.

      Did you try over the air update? Make sure you are on wifi and try during the week as sometimes servers are down during the weekend.

  • daniel

    i did not try the air update yet, i will do it when i am free. How do i delete titanium backup’s backup files? I need more space in my phone and do i need to delete superuser?

    • admin

      You can find TitaniumBackup folder in your SD or internal. You can try unroot in Superuser app.

  • Killi

    Need help please. Im following up on your site. Nice walk through S2 ROMs.
    Tried to flash remix 2.0 but Im gettin stuck on booting logo. Tried to install several times. Once with success but not for long. After aprox 1 hour switched to KERNEL PANIC UPLOAD MODE. I tried to follow all the steps:
    Reboot into recovery
    Wipe Data / Factory Reset
    Wipe Cache Partition
    Install the Main ROM
    In recovery go to Advanced
    Wipe Dalvik Cache
    Fix Permissions
    Wipe Cache Partition
    Im coming from:
    PIT –—> u1_02_20110310_emmc_EXT4.pit
    PDA –—> I9100_CODE_I9100XXKPA_CL51925_REV02_user_low_ship.tar.md5
    Phone –—> MODEM_I9100XXKPA_REV_02_CL1094591.tar.md5
    CSC –—> GT-I9100-MULTI-CSC-OXAKPA.tar.md5
    and CF-Root-SGS2_XX_OXA_KPA-v5.2-CWM5.tar

    I flashed partition table above as well. Can this be a problem?
    Flashing RR 1.9.1 same results: KERNEL PANIC UPLOAD MODE
    What shall I do make this work?
    PLS help to get it up and running. Appreciate.

    • Max

      I believe that’s same as ODIN download mode, you can try flashing a kernel using ODIN.

      • killi

        That’s correct. I can flash another KERNEL via ODIN its just the matter what KERNEL should I flash. RR comes with KERNEL already right?
        Today I took a chance and had RR 2.0 running all morning. About every 1/2 an hour is crashing and restart goes to that panic mode, then I have to press and hold switch button for about 10s to get it restarted. Now I end up with dry battery :/
        Where is the bug? What KERNEL or steps to follow you propose?

  • Adam

    Hey, Max
    First .. good work 😉
    actually i’m new in rooting! and want ask u abt somethings
    I want to root my international GS2 i9100. so, should i follow the steps on that video “How to Root Galaxy S2! [NEW][Works on All Galaxy S2 Variants]”

    – After rooting should i follow that video “Resurrection ICS ROM v2.0 for Galaxy S2 i9100! [Best ICS ROM]” to update my ROM ?

    – when i connected my S2 with Kies i saw this message:
    Your device does not support software upgrading via kies.
    Current Firmware Version: PDA:KF1 / Phone:KE1 / CSC:KE1 (XEU)
    so why my s2 doesn’t support update!? and does this ICS ROM V2 will upgrade my Android Firmware and Android version ?
    I hope you to answer me as soon as possible to start rooting.


    • Max

      tty the othet root method on faq then install new rom because its simpler process.

  • Kevin

    I just rooted my Galaxy S2 (Gt-I9100) by following your steps !!
    and i also did install the Batista FoxHound ICS [TouchWiz UX].
    It is absolutely wonderfully freaking awesome!!
    But i really just want to change 2 things for my phone..

    1. how to reduce battery? this rom has better battery time than before when it was natural phone, but still a bit more want. Any overclerking or others?
    2. I want to change my bettery icon on my notification bar into ICS battery icon (the blue one) with the percentage shows next to it. Is it possible to fix that?

    • Max

      Try setting max cpu at 800mhz that will underclock and save u battery.

  • visthu

    will it take much time for resurrection remix to load?
    ii got my mob struck in the last step.the screen with ICS symbol last for long time?
    could any one help me?

    • visthu

      how much time it ll take for resurrection remix to load?

  • Rafay

    Hey!! I want to know what is the difference between download mode and recovery mode?? And does the recovery version or anything related to the recovery has any effect on the rom installation???

  • Robin

    Hai Max
    Ik like your work very much, keep it up!!
    I want to buy a galaxy s2 but witch is better (also for rooting) the i9100 or the i9100G .
    And if i only can get the i9100G do i have a lot of Roms i can flash?

    • Robin

      No One? Can anyone give me some info on this?

  • victor

    I have a Samsung galaxy s2 gt-i9100 and i don’t really know where to start. I want to root my phone, new rom, etc.
    Maybe i still don’t get the root, kernel and rom concept. Please help me and put me in the right direction, how to start.

    • Max

      Root first then make a backup of your Rom then install a new Rom.

  • Jay

    need help i need to check if my s2 has been rooted and if it has been rooted how can i unroot it.

  • victor

    hello again,
    Managed to root and install a new Rom, but after that i tried to run some .avi files, doesn’t work. So is this a normal bug issue or i need some new players to install?

  • Tony S

    Hi Max,

    Here’s one Galaxy2 tmobile ICS rooted using Google voice leaves the old voice mail icon on the top bar and it doesn’t matter what if you change back, call yourself, wipe data, it doesn’t want to leave. Maybe someone has the fix I can’t find it.

    BTW: Thanks for all your help.

    • Tony S

      and the fix is……

      1: To fix this all you need to do is call your voicemail and leave a new voicemail, check it, and delete it.

      2: If you have call forwarding such as youmail, google voicemail, etc. Unforward your calls to the service by looking at your service’s FAQ’s once you have un forwarded the calls repeat step 1 above!

  • Balu


    I am using galaxy S2 with ICS(4.0.3), recently purchased,

    In my mobile there is no Contacts tab in my Call feature, can you please help me how to get the Contacts tab.

    Explanation- If i click on call button there is no contacts tab on top of the bar.If i want to go for contacts its not possible directly from the call feature, i have to come back and again have to go contacts. If my question is not clear, please share your mail i wil send screenshot across.

    Please guide me to fix this, thanks in advance.

      on custom ROM? Try another ROM.

    • Ed

      I recall encounter this kind of problem when phone just out of box.
      Phone appear charging but don’t pop up box with usb connected.
      Try other port or check the debug box in setting whether choose or not.
      That may not a problem with rooting.

  • Jay

  • Soldier

    How much time it ll take for resurrection remix to load?

  • gloria knight

    Hi, I rooted my galaxy ok becasue its working with the yellow triangle warning mark.. I thought I purchased Titanium backup and can see titanium pro in my applications but I only seem to have the option to uninstall and nothing else. I have a problem that I can’t remember what I had originally on the phone in software and kernel as I cannot find the list I wrote it on. Can I install any newer version on the GTi9100 which I got around January of this year if I need to. My kernel version is now -i9100XWKF3-CL276555 root@DELL101 #2 with build gingerbread.XWKF3 Android version 2.3.3. When I check for update it states there is on. Is this for the original version or the current version.. I am so new to root I don’t really know where to start. Any help appreciated.

    • Max

      Make sure u r rooted and titanium will work correctly.

      • gloria knight

        well i hhave superuser and yellow warning triangle so I can only assume I am rooted properly. However whenever I try to do anything on titanium there is no option. If I go back to the recovery menue everything I try fails. How else can I tell I’m rooted then? Failing that how can I get back to the original if I can’t remember what I had originally. Can I choose anyone that fits my model and upgrade from there. I’m not sure of the significance to the workings of the phone in the different version numbers.

  • Rafay

    Hey MAX can u provide resurrection remix rom for gt-i9100G…??? Or any other good rom for the ‘G’ variant which has no issues!! Waiting for ur reply!!! Thanks in advance!!

  • D’Jnr

    Hi, i am using samsung galsxy s2 shw-250k and i want to kne if u could help me out with the ics salman ROm also. i really admire your works with the salmon is and i would really be glad if you could provide a rom fr the korean versions.thank you

    • Max

      Sorry korean version is not really great for roms recommend staying with stock.

  • Jose Raul

    Viejo la version 2.5.2 para Resurrection Remix ya fue liverado y no lo has publicado, esta actualización esta mucho mejor y arregla varios problemas que presenta con GPS el RR 2.4.1, el manejo de la pila sigue decreciendo en su eficiencia pero igual es mucho mas veloz y la interacción de la rom es aceptable…

  • Martin

    I couldn’t understand the last question, however I have one of my own. I have now downloaded thee versions of R.Remix including the last 2.3.5 and every time I try to flash the rom using cwm Iget the message “installation failed zimage not found” why?

    • Max

      Do not unzip the files after downloading, use the zip files I think you are unzipping them.

      • Martin

        I have tried both ways , I managed to flash other roms eg “salman” no problem

  • Pratibh

    Hey, So i rooted my phone( running ics 4.0.3.) via the method you have given,everything went smooth and nice,superuser came up and i allowed it and all, i can also flash roms,as i tried with the Resurrection remix 2.3.5, also step by step as you had told. The problem is, i cannot use titanium backup,as it says i have no root access,even after giving it superuser access. Then i got root checker from the market and it says i have NO root access,which can’t be cause i did flash a rom. Apparently, i have no busybox either. Please help me out here,this is the first time i am rooting and stuff,any help would be really really appreciated
    Thanks !

  • Neutrino7

    I have just updated my S2 from XWLP7 to XXPQ6 and I found that the phone was no longer rooted. Still worked fine although I now had some useless rooted apps on my phone. I had rootbox on the sd card so I tied to install that but message came up not recognised , I started odin and tried to root with a cf root that I had used successfully before but that failed . I then in pda tried to install “19100xwlp7 19100DDLP INU which I had used before when soft bricked but again failed. I was now desperate and in my haste in pda I put XWKDD which sadly odin passed and to my cost I now have a semi hard bricked S2. Is there any thing any body can do to fix the situation?

  • Aung Than Tun

    I have already upgraded my mobile to ICS but I cannot download from google play. So how can I downgrade gingerbread 2.3.5(origenal version)?

    Dear all pro, I have a major problem and tried to solved with Tmobile tech support but they stay away of this issue. My new galaxy t989 bought from Craiglist is not working after a message sent by tmobile for Update my phone. My new phone was working perfectly in two days but now is freeze. I got a message from tmoblie this morning said “congrat, you have an update for your phone, please click Yes”, then I click YES and it said “new update will take up to 10 minutes, click OK to start”, then I press OK. The screen become White color with blue words ” Software Update” and ” Loading..” below it. After 40 minutes, it remain a same picture “White color with blue words ” Software Update” and ” Loading..” below it.” I called tmobile for trouble shoot for 1 hour, end up they said this phone is not purchased from their store and it cannot be repair. Please help me to solve this problem, I do not have phone to use it now. Every time when I remove the battery, turn it back on it will show “White color with blue words ” Software Update” and ” Loading..” below it.” Can someone help me please………………..

    • Max

      works, everything on this site that says Galaxy S2 is for i9100 unless it specifically says for AT&T or Tmobile.

      • steve

        cheers, thanks for the confirmation, time to play!!! 🙂

  • Neal

    Hi max, 1st – Great work with ur tutorials!
    Im a beginner with a fair idea of it all.

    I want to know for someone like you, who switches roms day in and day out,
    whats the best way to keep flashing to try out new/custom roms and still keep(or restore) apps and data(settings,contacts,sms,pics,etc.)
    I recently got my phone restored(by samsung due to software issues) and i had done a backup on SD card from ClockWorkMod but when now i went into recovery and installed and then tiered to restore it said no backup found. So lost everything.

    So whats the best method to flash? To Backup?

    And can i root & unroot without loosing data?


    • Max

      I use GMail for contacts and Titanium Backup app for apps/data, that’s about it. Also I do make a backup ROM if my current setup is good which backs up all my apps, settings, contacts, everything so I can go back to it if a new ROM doesn’t work out for me.

  • Tashbeeb

    Does it work on android version 4.0.4?

    • Max

      yes ICS = 4.0.3/4.0.4

  • Hanzala

    I’m planning to root my S2 which is not upgraded to ICS yet
    Which means it’s still gingerbread 2.3.3
    As I want to recover my data which is important and data recovery app is only for root user so I need to ask that is it possible for me to root my samsung galaxy s2 with gingerbread version 2.3.3 without upgrading it first to ICS ? A step by step guide link would be appreciated though!
    Secondly I want to ask that after a root process, do it requires you to factory reset? Or any thing like that which may cause to effect your Internal storage data or deleted files?
    Kindly Reply me as soon as possible.
    Thanks in advance 🙂

    • Max

      You can use this method to root on Gingerbread:

      That root process does not erase anything no but if this is your first time rooting, make a backup of your internal before doing anything, just in case.

  • ron

    hey just rooted my phone galaxy s2 try to cuztomize it then it asked me if i want it to reboot i said yes but its now taking ages to reboot why does it reboot for ages???

    • Max

      you mean installing a new ROM? Sometimes that may happen.

      1. Doing a fresh re-install.
      2. If that doesn’t work, try another ROM.

  • ron

    how can i fix it to get it back on thanks

  • bernard


    • Max

      It’s usually normal, should go away after couple hours.

  • Irfan Raghib

    Hello Max,

    Come to Pakistan and you will have good food here……. r when I will visit USA again in FEB 2013 will try to see you…

    I need your help. I bought fresh factory unlocked Galaxy S2 White……. Used it for about 9 months…… Suddenly one morning it popped up “Enter Network Security Code”……… Why???


    I tried to root it……….and……when installing new ROM in the middle……… phone went off like it never gets on……….now…………completely off black screen………no signs………….seems it is hard bricked………..

    ROM that I was installing is for Galaxy S2 i9100 and this is my model no.

    Pls. help what to do?????


    • Max

      not sure why that’s happening if you didn’t install a new ROM. Did someone steal your phone and add SIM lock perhaps????

      • Irfan Raghib

        I was installing new ROM and when the phone was in the middle, it bricked and went off…. after that it never showed anything on its screen…… I am unable to on it……. Just black screen…..

        I think it is hard bricked…………can this become on in ODIN mode with USB Jig???


        • Max

          I don’t think so. You might need JTAG repair, try mobiletechvideos.

  • vaishali

    Hi max,

    Great website ! I have to ask what is the best ROM for a galaxy s2 GT-i9100 I am a newb all this i hv just recently Update my Galaxy S2 GT I9100 to Official ICS 4.0.4 XWLPX Firmware using odin 🙂 So I am looking for a ROM that improves battery life and performance and has no bloatware…
    will Resurrection ICS ROM v.2.5.3 for Galaxy S2 i9100! [Jelly Bean Transitions][Best ROM] work for me? how do i do that my device is not rooted.
    Thank you.

    • Max

      root your phone first, then try couple custom ROMs, they all do have battery life/performance improvements over stock.

  • cyiam40


    is there a good ICS and/or JB rom for US Cellulars SCH-R760?

  • Simon H


    Followed your steps on ODIN and all seemed to go ok.
    Only issue is when I try and use Superuser to update binaries I get to the point where it tries to look for root permission but it never gets it no matter how many times i try.
    I’ve gone into CWM mode from boot so that is working.
    Any reason why it wouldn’t have rooted corrctly and how can I resolve this?


    • Max

      You don’t have to update the binaries that’s just optional but if you have root that’s all you need.

  • abdul

    I think that more and more people have a same problem with custom roms, becouse of ”sim lock” issue. I have a Galaxy S2 gt-i9100 from a diferent network and it works awesome with resurrection remix rom 3.1.2, but when i try to install a newer rom i constantly having the ”sim lock”. If anyone can find solution for this problem, it’s you! Please respond!

    Need help. I rooted my GT-I9100 4.0+ yesterday and after a bit of issues (won’t boot) – it’s up and running. However, I have couple issues and need some help.
    1. My bluetooth has quit working?
    2. I cannot connect to Kies anymore – keeps failing for MTP usb driver failure.

    Any help will be appreciated. Have searched and tried several recommendations from google.

  • Tom

    Hi, i have a rooted S2 on 4.0.3 but want to update it. I have no clue how to go about this, do i need to unroot it, officially update it and then root it again??? Any help would be good!


    • vetteengr

      I believe all you need to do is burn one of the newer ROMs that are posted that match your phone and you should be good to go – shouldn’t have to unroot it.

  • Angshuman Dey

    Hi Max!

    Can you suggest the best ROM in terms of latest looks and battery backup.

    Currently I am with Resurrection Remix. Bored of it!!! 🙂

    • Angshuman Dey

      I have switched to Biftor ROM after reading your post about it.

      It’s pretty cool.

      Good Battery Life and customization.

      Thanks again for helping.

    I have installed many different roms in the past but none as awkward as mr1 milstone. I installed it the way I alwys do ,wipe cash+ dalvic cash and then flash zip .when rebooted no apps no play store therefore no titanium backup .So download play store via pc because phone will not now download anything. but the launcher will not work. the phone is now a very primative device. I came from mr1 v6 Do you have any idea what has gone wrong?

  • Luka

    Hello, can i simply load a 4.1.2 rom into odin instead of ice cream sandwitch rom?
    Will it work? I want to speed up my update to jelly bean from a rooted ics..(I9100XXLPS / 3.0.15-I9100XXLPQ-CL223505se.infra@SEP-94#3 / IML74K.XWLP7)
    And which 4.1.2 rom version to download? I’m from Slovenia and i have a gt-i9100 that i got from a stoagehouse that was only importing the phones from Hungary and forwarding the phones to another country…Also the language was hungarian when i bought it, that i changed to slovenian and could be changed to any other language… On SamMobile I was checking out firmwares: There are 2 firmware versions avalible in Slovenia; 2 carriers: Simobil and Mobitel. I currently use Mobitel’s sim card!
    Simobil’s version is I9100XWLSD(4.1.2) and Mobitel’s version is I9100XWLPD(4.0.3). I think that is correct, check it out just to be sure. My question is: so will i be able to make calls, text and use data transfer on both versions, what is the diference(besides the version) and should i download Simobil’s version version from this tutorial:
    I Thank you very much!!!

    Hi, I watched the video on rooting 4.1.2 and I have a few newbie questions. Sorry if they seem basic. I just can’t find the answers.
    1) Why must you install a new kernel to replace the stock JB kernel in order to put on CWM and then root? Is there a problem with the stock kernel’s ability to support CWM?
    2) Does the jeboo kernel leave touchwiz intact or replace it with something else?
    3) What is the difference between a kernel and a ROM? You have videos for installing both, so I am confused. It appears you must put in a new kernel to root with CWM, then use CWM to put on a custom ROM. What happens to the kernel you previously put in when rooting? No longer necessary?
    4) If you get an Android update, say 4.3, and you have to unroot, do you have to go through the steps again to 1) replace the kernel, 2) install CWM, 3) root, 4) and then add a custom ROM?

  • Juan Castro


    I need your assistance. I have a Samsung Galaxy S II GT-i9100 GSM, I rooted using your method, great tutorial by the way, but I unrooted to a stock rom as well using one of your tutorials. After I root it the first time and before I flashed a different rom I saved the rooted original rom, the one with the provider stuff on it. Can I go back to that rom again? I am unrooted right now.
    Thank you, I hope I made myself clear.

  • Juan Castro

    Hi Max,

    Its me again, I was able to root my SGSII GT-i9100 GSM again, but I am having a lot of problems with it specially with the battery, it turn off by it self and shown as no battery, when I finally able to turn it on I have more than 50% of power. I wanted to restored it to the original rooted stock rom that I saved the first times but seems like it is not doing it. If I connect the phone to Kies it saids my current firmware version is not compatible with an update through kies. I don’t mind to be rooted but this problem with the battery is driving me crazy. Any help you can bring me will be highly appreciated.

    Hi I’m a noon with i9100t that I rooted and flashed with cm10 Extreme 4.1.1 beta ROM unlocked from VAU using heindall. It has been glitching a fair bit, and sometimes gets pretty hot and high battery drain at the same time. I have tried milestone mr2, chameleon, avatar, and recently extreme 4.2.2 stable, but none of these would unlock using busy box

    and galaxy s unlock from helroz. Over the weekend I flashed jellyam, which was great at first, but started locking 2-3 times a day, and internet was problematic. Have restored extreme beta, but now having net problems and modem is xxls6. Im sure it was dulp4 prior to flashing jellybam.
    I am normally fairly tech savvy, but recently got dercums syndrome which gives me massive headaches, mobility probes, and goldfish memory, so m struggling somewhat and highly dependant on my phone and net.Any suggestions for fixing this? p.s. if I don’t thank for helping it is memory not lack of gratitude. Thanks in advance

    Hey, I have installed CyanFox ROM (Android 4.4) recently but it’s not what I have expected. Before that, I have used Carbon ROM (Android 4.3.1) for just one day before the battery went empty and the phone has then frozen when booting at the screen with orange triangle. And before that, I have used AOKP ROM (MR1 milestone 1) for quite a long time. That’s the facts. Now the problem is that when I have tried to reinstall Carbon ROM today (this time with /system format), it gave me Status 7 error, then after following some guides it gave me Satus 6 error and now I’m really frustrated because the only ROM working is CyanFox and even the restore for the AOKP backup that I have made doesn’t work. Is there some issue with downgrading to older Android versions I have not heard before? And could you please help me out of this deeeeeep shit? :-/

    Thanks in advance!

    hey sir can u tell me how i can use 3g or video call from samsung sghi777 there is no option of video call in dailer of phone i m using stock version of jelly bean

  • Sojo

    Thanks for the instructions on how to unroot my SG SII was successful. However not in the way I expected.

    I loaded the UK 4.1.2 Jellybean stock (as was my previous ROM) in the hopes that I could get a Banking App (Barclays Mobile Banking) to run as previously before I rooted my device. This app will not run if it “senses” the device is rooted. I came to reinstall the app and run it. Unfortunately it says the phone is rooted.??

    Also none of my installed apps or configurations where changed on reboot after “unrooting” with stock ROM per your instructions with Odin. I know the update was successful because the boot splash image is no longer the original carrier image.

    How can I be sure this phone is really unrooted and if it is could you advise why the banking app still thinks the phone is rooted… would appreciate your help I really want this app to work.

    Hi, many thanks for your great site and very informative FAQ’s…I have succesfully unbricked my Galaxy S2 i9100 thanks to your site….However I would have thought that going back to stock rom (4.1.2 jellybean from gingerbread) I would have unlocked my phone from Orange (EE) as I had put a new sw and rom on to it?? Is there a way I can check the unlock code from the phone?? (when in recovery mode etc) or do I have to visit an EE shop and give my IMEI number in order to unlock the phone….I wish to go onto vodafone sim (PAYG)
    Any info or suggestions would be very much appreciated,
    many thanks,

    • jagman

      Hi, reference my last posting…don’t know if it makes any difference but I am in UK and would like to unlock my i9100 from EE to vodafone,
