  1. Tony says:

    I have already installed the leaked 4.1.2 unrooted version. Can I use Odin to reflash your rooted version or do I have to flash back to 4.0.4 stock, root and then flash your 4.1.2 rooted version?

    • iZel says:

      same here! too bad for us, i think we need to flash it again using this rooted ROM.. tsk! tsk!

    • Max says:

      You can just flash over fine.

      • nick says:

          • ram says:

            you can create an package, all you have to do is open titanium back up and click on the left soft-key, in that find option save in a place where you know. once after flashing your new rom, you just flash this zip by locating the place where you created the or, at the same time using Clockwork recovery mode, the same way you do for flashing the rom. it will install titanium back up application.

            hope this helps… :-)

  9. Rahul says:

    Hey max i follow ur website a lot and i am on ressurection remix with dorimanx kernel so how do i get back to official firmware ? cant i just flash this rom in recovery like the others ? sorry, i know its noob question just to be sure :P

    • nick says:

      If you download this file you have to flash it via odin, but zedo is working on the cwm version so we can flash it through recovery mode. :D:D

  10. Tom says:

    Hi, I flashed this rom on my sgs2, having resurrection remix installed before flashing. After flashing I got a strange query for unlocking my sim card. It appears after entering pin, but it doesn’t accept pin, so I click ‘skip’. Then there I get a notification ‘No service’ and network doesn’t work at all. Choosing network manually in network settings didn’t work :( please, help

  11. alexcustodia says:

    I just installed this version. It’s ok. No errors messages when I installed. It’s a very responsive and smooth version I tested till now. Thank you!

    • Muli says:

      thank you for the briefing review!
      let us know if it have any bugs…

      Im preety new in all this buisness and searching for stable and comfortable rom… :)

  12. Kenji says:

    Guys just download the firmware. After its downloaded open odin then hit “pda” then select the firmware you downloaded, then put your phone in download mode (volume down+center button+lock button) then plug your phone in your computer via usb and hit “start” then thats it :D!!

  13. Ben says:

    Is this for the international sg2

  14. pratik chirkute says:

    Flashed it. Working very satisfactorily. When I was using the custom roms I actually missed some previlages by samsung like direct share. This rom is nice only issue is the memory. Takes lots of memory so I uninstalled some of the system apps which I dont think I require like video hub etc.

    All in all the rom looks good and if we can manage the RAM memory properly I think it should be the rom with which we can stick for a while

  15. harshal says:

    can u make another tutorial on only how to root this coz i have already installed the leaked version from sammobile…

    • pratik chirkute says:

      1.Download the tar File
      2.Start phone into download mode odin
      4.connect mobile with cable
      5. Click on PDA and select tar file on start

      For more information Google how to flash tar through odin:-)

    • Serge says:

      I believe it could be easier using Odin Mobile, you don’t need to link you Galaxy to the PC. Odin Mobile is doing everything, wiping and so on… Just transfer the Rom file on the Galaxy and start the program. When it starts again, you’re under the new Rom…
      Could anyone confirm ?

  16. Metadavid says:

    Thanks for this. Just installed on S2 and is working fine, no worries!!

  17. ahmad says:

    I have ICS on S2 rooted with the CF-Root kernel. i have backed up the current system with CWM (clockworkmod manager). Also i have backup the applications with titanium backup. after i install this rom, can i switch back to the ICS with CWM? please post the guides if possible

  18. Jure Lakner says:

    I have a question.
    Can I instal this ram just by flashing it on my phone, like other rams?? Not to go in to download mode just by instaling just by ur phone and not eith cp??:)
    Help pls

  19. tendo says:

    When i go to flash using odin, do i extract the files from the zip folder or do i load the zip folder into odin?

  20. Ashley says:

    After flashing this rom it says to unlock sim lock. and after entering pin, but it doesn’t accept pin, so I click ‘skip’. Then there I get a notification ‘No service’ and network doesn’t work at all. its like my sgs2 is not sim free anymore. please help

    • Parma says:

      I just found that you can unlock your sim by using “galaxsim unlock” from Play Store.
      I haven’t tried it yet but can you try it & reply me later bro.
      You download the app from play store,run the app & re-boot your mobile.

    • Rahul says:

        • Tommy says:

          I thought i was the only one with battery problems. This sucker is great but the battery bug or whatever it is, it’s just a pain. 5 hrs and i have to charge my phone. I like the Rom but i’m thinking of going back to 4.1.1 but well i don’t know this thing is pretty darn sweet so i may just suck up the battery issue and crack on.

          • Noki says:

            Had same problem with battery thought I was the only one. A day it was chewing up 3 batteries when 1used to be enough for normal daily use. But with 4.1.2 7 hours standby and 30min of screen use. So I had to downgrade to 4.0.4

    • nick says:

      I had the same problem when i created a shortcut of odin in my desktop.

  32. Behman says:

    My phone got SIM locked after this… what should i do?
    I have tried to Unlock it using Galaxy S Unlock, but did not work…

    • Parma says:

      Try installing “galaxsim unlock” from google play store.After installing & running app it’ll tell you to pay a meagre fee of $2.56
      But it works great I’ve tried it bro.Worth every penny :-)
      Dont 4get to shut down and start your mobile after unlocking has been done by app.

      Give it a try bro.

  38. bkr says:

    how to transfer tar file to zip file ???

  39. voveris says:

    Great ROM! looks exactly like Galaxy S3, just dont forget to backup contacts, sms messages etc..

  40. Maryus says:

    Please! anyone knows a kernel that can do dual boot with this ROM and ICS? Syah Kernel 5.0.1 doesn’t support this leaked official JB version, only CM and AOKP JB versions! by the way, if anyone gets network locked, contact me, i am gonna help u for free because i got locked too and i suffered so much a couple of days until an app saved me! the Galaxy s unlock app unloked it just for once, if i would restart my phone, it got locked again. Please help with the kernel!!!

  41. Pieter says:

    I was running Ressurection Remix with a Siyah kernal (maybe not the latest, but close). This is what I did and it worked.
    1. Backup up everything (incl. titanium backup all apps)
    2. Switched off phone and booted into Recovery (vol down + menu + power buttons)
    3. Made sure samsung usb drivers were installed.
    4. Ran Odin then plugged in the phone (waited for odin to recognize the phone)
    5. Clicked on the “PDA” button and selected the ROM and hit start.

    After the fresh install I downloaded titanium backup from the play store and directed it to where my backups were and reloaded all my apps (note, not any system apps.) Three out of the 90 something apps had some issues, but I will just re-download them from the play store.

    Worked like a charm. Didn’t worry about a kernal or anything. Jelly Bean is awesome!! And still have root.

  42. Pierre says:

    Great ROM! Buttery smooth and works like a charm! Injecting root is like icing AND cherry on top!

    2nd day since i flashed this and haven’t found a single issue, not even FCs (crossing fingers that i

    Note: Flashing this ROM will wipe your device. Make sure you backup contacts, messages, accounts settings and the likes.

  48. phlipms says:

    Max please help network error problam please solve the error.

  49. Mhenni_b says:

    I have tried to unlock sim on this rom but it doesnt work :( the only solution i have found is to be back on 4.0.3 with odin; root it and finally unlock sim freely through installing:
    1- titanium backup
    2- busybox
    3- galaxy S unlock
    do the three steps on galaxy S unlock and your network will work again
    R: You can install custom rom again :)

  50. arshad says:

    if i upgrade to this rom using odin , how do i get back to my previous rom if i want to?

  51. arshad says:

    i mean i dont have cwm in this rom so how do i get back to my previous rom???

    • sercour says:

      First thing to do : get a copy of you actual ROM,
      Then flash the new one with Odin
      When and if you want to come back to the previous one, do the same but with the “copy” you had downloaded before..
      That’s all Folks…

  52. Massa says:

    This is beautiful and good rom, but batterylife is poor :/

  53. Gabo Carreón says:

    Hey Max, is there anyway to install CMW on this Leaked Version yet?

  54. Martynas says:

    I have an issue using my GPS with this rom.
    It says ‘your current location is temporarily unavailable’ all the time.

    GPS worked fine with other roms. Anyone knows how to solve this issue?

  55. Shashank Hegde says:

    Flashed the ROM using Odin 1.85 .
    Wonderful ROM.. Loving the small features it included inside.
    After loading my back up apps found that its getting laggy.. The battery life is also not like expected.
    Got the Quadrant score of 2890 which is quite good..

  56. Arun says:


    Jus intalled this Rom on my I9100P. Was on CM10 earlier and really missed the MHL capability.
    Can someone let me know how I can install the NFC patch for JB now that there’s CWM in this Rooted Leak.

  63. johnb says:

    I’m in Canada (Vancouver) and am on Fido. Installed this and now APs listed are Fido LTE, LTE Tethering and chatr-Internet. What happened to the “normal” Fido APs? I don’t have data any more.

    I got the same SIM lock issue as others, but solved it with the Galaxsim Unlock that was mentioned earlier in this thread.


  64. Doc Bob says:

    I also have sim lock problems but as mentioned earlier Galaxsim unlock did the trick for me.
    I also had camera problems but re-installed the other version ROM and it sorted itself out.

    Doc Bob.

  68. Ed says:

    [WARNING] – this rom cause soft brick to the phone!

    I’ve loved this website so much. BUT recently i installed this leaked version rom and few days later my samsung galaxy s2 unable to start and stuck in bootloader. i realised my recovery mod was gone since i installed this rom. i tried to flash using ODIN but every else failed. I couldn’t use my phone for the moment.

    I’m very much troubled by now. Hope someone can help me.

    • Ben says:

      I had this type of your problem before but not with this leaked 4.1.2 rom. I solved the problem by flashing my phone with 2.3.3 (I9100XWKE1_I9100XXKDJ_I9100XEUKD1) stock rom, Hope this will help you too

      • Ed says:

        the thing is i had tried to flash many original ICS firmwares and non succeed. all stops at “NAND rewrites”. and the worst has happened, my phone couldn’t turn it on and is dead. totally dead.

  69. LIJO says:

    ED does ur download mode works???

    • Ed says:

      Hi LIJO,
      now nothing works. not recovery nor download mode. computer can’t even detect the dead phone. any idea?

      i’ve send to a professional repair. it took 3 days and he gave up too and couldn’t do anything.

      • LIJO says:

        ED :dnt loose hope ,
        one last thing u can do is
        Buy USB JIG,

        1) Switch off your phone. Wait for 15-20 Seconds till the phone vibrates.
        2) Plug in the USB Jig into the Micro USB port and wait for a few seconds.
        3) The phone will automatically boot into download mode.
        4) Once you are in Download Mode, Unplug the USB JIG from the mobile.
        5) Connect your phone to PC using the USB data cable.
        6) You can then install your favourite Custom/Stock ROM of your choice using ODIN

    This is the most stable rom i ever used. No bugs with this rom. Sometimes i get crash reports. But i dont think it is about this rom. Whenever I messed up my phone i downloaded this rom and saved my phone.
    Thanks too much.

  79. ABXS2 says:

    this rom is awsomely superb…. buh it … it locks my sim and now iam unlocking my sim with (ROOT) galaxy s2 sim unlock..

  80. John says:

    Hey Max,
    Where have you been ?? You haven’t reviewed a ROM for a while ?? Did you stop reviewing ROMs for the S2 ?? PLEASE SAY NO !!!

  81. Amith says:

    Why is there 300MB size difference between the rom file here n that leaked on xda. The file size here is more than 800 Mbs while on xda and other places it is around 550 MBs ?

    • Kyle Galicia says:

      There are two versions of this rom. The unrooted and the root injected. The unrooted has the smaller size.

      • Dharmarth says:

        Can you please help me in understanding why would rooted ROM would take 300 MB extra? If I am rooting using other applications/tools, that is hardly few MBs in size.
        The huge size of this ROM holding me from using it.

        I would very thankful, if someone can give me idea about why rooted ROM taking so much extra? Is it the case of not optimized compilation?

  82. udara says:

    visit for daily updating roms…….!!!!

  83. Kyle Galicia says:

    Hey max. My sgs2 is running this rom and I want to install gapps 4.2. Ive downloaded the file, switched to recovery mode, factory reset and wipe cache, then install zip. Then it says e: signature verification failed. Pls help. Thanks.

  84. Shouvik says:

    I have installed this leaked ROM (4.1.2) via mobile-Odin pro and got it rooted automatically while flashing.All features are nice except the ripple effect which is not working(doesn’t matter though). But the battery life is terribly poor. Hope this will be ironed out in the official release.If it’s taken care of, it will be one of the best upgrades for S2.
    “Smart stay”, “floating video player” etc are really nice features to have inbuilt.

  85. Tashbeeb says:

    Works like an absolute charm!

        Please let me know about battery life. I am not getting more than 12 hrs

        • serge says:

          Do like me Majn, I have changed the battery for a 2000mAh one, let’s say the device is looking a little bit like a beluga, but I won a double life… and since the change, “no problemo”. I can use it fully more than 2 days…

    Hi, I flashed this rom on my sgs2, having resurrection remix installed before flashing. After flashing I got a strange query for unlocking my sim card. It appears after entering pin, but it doesn’t accept pin, so I click ‘skip’. Then there I get a notification ‘No service’ and network doesn’t work at all. Choosing network manually in network settings didn’t work please, help

    I just love this rom.
    everything is working smooth and flawless…
    just one great problem…after I flashed it it locked my phone so had to pay and use the “Galaxsim Unlock” application to unlock it.

  97. Johan says:

    Using it and so far its looking great. Just 1 thing after using ODIN, CWM has disappeared but it looks like phone is still rooted. Any comments or help would be great.

  99. Major kumar says:

    I got sim locked …terrible battery …hangs lot of
    Times ….think once before install …you don’t need all the
    Crap to waste your valuable time … roms after at least
    80%sure ….at least

    • Kamelman says:

      That`s what you get when you buy a previously network locked S2 (also know as second-hand or maybe stolen and unlocked).Haven`t had issues with this ROM at all,no sim lock when i installed`it…battery holds up pretty well (12-14 hours,and i use my phone a lot) does not freeze or crashes.I flashed`it with Mobile Odin,kept the root and SU.I`ve had my phone for more than a year now,went through all kind of custom ROM`s (got most of them from this website) and i can say hand`s down that none compared to this one (i got better signal,faster internet…even the screen looks somewhat ..brighter\better).And i`m willing to bet that it will be one of the most used ROM`s once Siyah will release a kernel for it (haven`t seen one so far …though i haven`t even looked for one).It`s bug-free (unlike most custom roms) ..and pretty much flawless imo

    i fix my sim unlock problem with galaxy s unlock….but the problem is
    after reebooting phone again same sim lock prob….how to fix…?

    • Prabaz says:

      @Manoj – Just email me – I’ll give u the link of unlocking APK. (

    • John says:

      Use GalaxSim Unlock …its the only app that works at the moment for the new update

      You can get the free version XDA….Spocky’s forum ….just don’t update it or you will need to pay 2 bucks to unlock …..but making a donation to Spocky is proper for all his hard work ….so its probably better to pay 2 bucks …..its unlimited unlocks !!!

  102. Prabaz says:

    Just got an additional 48GB of free Dropbox space by going for this Rom….

  103. best ever everything is ok I love this jellybean firmware, anyone want to install than don’t hesitate this is original

    Have we established if we can use a kernal with a dual boot option and if so which one?…

    • John says:

      Gokhanmoral creator of Siyah kernel is developing a dual boot kernel as we speak for GS2 …..he just completed for GS3

      • John says:

        Siyah kernel is ready for the GS2 on JB …version 6.0 beta …but its not dual boot yet & has many bugs ….so some patients ! ;-)

    Dear frnd, after updating my s2 with 4.1.2, my mobile battery backup time too less
    Pls help me…

    • Serge says:

      A long time before upgrading the version, I have changed the battery for a 2600 One.
      And since that, I have no problem…

  112. Rohana says:

    I have been running this rom for a while and the battery life has been terrible. Now I would like to install a different custom rom. But CWM is missing after this rom is installed even though it’s rooted.

    How can I install CWM or is there any other method to install another rom?

    • John says:

      Hi ….i think have an earlier version of Rainbox Rom …so would you need to factory wipe & install another Rom …..then flash Siyah kernel & you will have CWM back

      Or you can flash the newest version of Rain Box that has Siyah kernel support …then you should get CWM back

      • Rohana says:

        Thx for the reply.
        But how to flash another rom without CWM? I am having the stock boot loader.
        Do you mean using ODIN?

        • serge says:

          Yes, you can use Odin or MobileOdin,
          and better Rom Manager can be used to flash your CWM…
          or try to directly download and install

    How to get out of this Rom… pls Reply

    • serge says:

      What do you really mean by “get out of this rom” ??? What do you want to do ?
      The solution could be in flashing another one, or to come back to the previous you had.
      In the second case, or you flash the back-up of the previous one (if you did it – I wish it), or you download the previous stock version and flash it…

    • John says:

      fatory reset ..etc …flash Dorimanx kernel v7.38 has dualboot support

    • Kyle says:

      Get temporary cwm. Search xda. Then flash new rom. Simple.

  119. ip5 says:

    you guys need to read the tutorial very well,
    it say you need a ROOTED gs2 from the start before you guys install this rom.
    its no wonder your sim networks locks up.

    Hey I cant find the exsdcard…. its not working, and when I open it it closes the file

    • serge says:

      Yes, that’s the only bug found (until now)
      The external SDcard seems not to be found, but one can see it with Windows Explorer and all the files when one use Kies…
      I have found a solution :
      - to copy all the files on my PC respecting directory names
      - reformat the external card
      - to start the apps using the external card in order to create new dedicated directories
      - to copy all the files back on the card in the new directories
      if anyone has a better idea ????

    I have upgraded my Galaxy s2 thru Samsung Kies by yesterday with the following version

    Android Version – 4.1.2
    Baseband : I9100XXLS8
    Kernel – 3.0.31-889555
    Build No. JZO54K0I9100XWLSD

    After 100% full charged by this morning, i have never made a single call from this mobile and my battery got down to 25% with over heating on device.

    Before i was using gingerbread 2.3.6 and it was so excellent and i get the battery backup of 24-30 hours with full of usage.

    Please advise me and let me know the best firmware where to download.
