Hi…I just want to know that is it good to root android devices like a GS2 ?…m actually looking forward to buy this device after a long wait and thus want to be rest assured before playing with it…i just want to know about the disadvantages of rooting GS2
Thanx
OH yeah, GS2 is the best smartphone on earth right now.
Admin,
I tried to follow your video and instructions for rooting my S2 with a MAC and got the same errors almost everyone talked about in the comments below but it appears no one is answering any of the problems. Can you please tell me what I’m doing wrong? I followed your instructions exactly, including using two “–” instead of one as your tutorial says to use but your video uses two. Both ways do not work for me anyway. Here’s what I get;
Initialising connection…
Detecting device…
Claiming interface…
ERROR: Claiming interface failed!
Please help.

for some reason after i rooted my galaxy s2 the wifi wont work can you help me and sorry that im posting on this i just need help asap
Hi MAX, I really appreciate your help. I was so impressed with the effort as well.
recently i have rooted my galaxy SII as you said in your blog, but I forgot to back up the original one. every thing is fine, but its keep on saying “process.google.com” didn’t respond properly when ever i restart. also I got recent update to ICS from vodafone (Australia). i am able to download, but not able to install it, its always getting failed. also not able to connect kies in computer using USB. My question is how to upgrade to ICS now. is it possible to upgrade now as it is rooted. do you have any BEST kernel for ICS. please reply me. I really appreciate your help.
also i have rooted as you said in the new method just using the “GalaxyS2RootNew” and runme file. I dont know whether that kernel is the right for me or not.
Thank you.

samsung model sgh T989 T-Mobile
I’m new to the whole rooting and modding my droid. I have a AT&T galaxy S2 and with your tutorial i was able to root my phone. I been looking around on how to change the boot animation. I downloaded root explorer, i downloaded a animation i found on png format. when i went into my system/media section there was a no bootanimation.zip but i found ODEAnim.zip and sanim.zip. i tried moving the bootanimation.zip file from the sdcard to the system/media section and animation didn’t work, i tried replacing the ODEAnim and sanim zips by renaming bootanimation.zip into those and still nothing. i tried unzipping the bootanimation.zip first in the sdcard then moving it to the system/media and still get the boot animation i got with your kernel. is there a way i can change it, maybe since im new im omitting something. can i delete ODEAnim and sanim zips? . any help will be appreciated.
thank you

hello ZedoMax. Can you share a basic outline of what you needed to do to build the zedomax kernel from source?
You indicated that you spent a lot of late nights, etc. Can you share your learnings.
(I have downloaded the source from samsung open source)
What linux distribution did you build it on?
What version of GCC? etc.
I want to learn a little more about the internals of the building of kernel images for this device I777
Any response,
Thanks.
Do you know why any of the roms I install none of the data services work wifi or 3g?
i have T-Mobile SGH T 989 wanna asked about nomination from you for the best kernel in your opinion (which you prefer to use always )

Thank you for all your efforts I just want bring up about Samsung Kies offering latest upgrade firmware which is fine but for some reason is very hard to root the Galaxy S2 T-Mobile again.
Hey guys, love the website.
I successfully rooted 2 t-mobile sgs2 t989 and flashed the beastmod rom that you recommended, really good stuff.
Has anyone got the OTA 2.3.6 update sent by t-mobile? I have tried looking online for any tips on how to install it without losing the root or disabling the auto-update function. Is my only option to unroot and install and then re-root the device?
thanks.
Any ideas on hot to root Verizon charge?
Will this rooting work on my samsung Galaxy S 4G smart phone?
According to the directions: When I hold down the volume and power buttons, nothing new seems to take place??
Always update me with new SII issues, Thanks.
Hi i just rooted my Tmobile GS2 and i got a notice that a new update was available form Samsung. Upon trying to update, the system reboots and it cannot continue as it seems to enter “revocery mode” (unsure if that’s what you call it when it’s DOS lookinig). Anyway, how do i proceed. I currently run 2.3.5.
Thanks,
Danny
I have not start to root and flash any rom into my Tmobile Samsung Galaxy S2 – T989 , but this site gave me all the information I needed.
However, I read many T989 IMEI got corrupted because of too many flashing. Did this happened to yours at all?
I read many site, saying backup restore of efs folder only work for ATT Version but doesn’t work on restoring IMEI on Tmobile T989.
Care to make a video that discuss this in the near future?
Thanks a million
Hello!
Thank you for your website!!
One question: i have rooted galaxy s2, change 15 custom roms, and still there’s one thing on every rom seam to appears: when i try to connect bluetooth on main screen, with scroll down options, there’s icons of: wi-fi, bluetooth, gps, auto totation; when i choose bluetooth first appears sound and then icon of bluetooth with this sign ”?”, despite of that, bluetooth works, but that’s really annoying! What is that, how can i fix it?
Now i am on VK ROm, is excellent, but still problem like i said: bluetooth with sign ? beside.
and one thing: beside icon of bluetooth appears these words: ”bluetooth available”
Ever since i rooted my tmobile galaxy s2, every time i reboot the icon layout resets and my background resets. Why does this keep happening?
Hello,
I got a new S2 from UK (3 network) which had a jail break in India. I hope my S2 my infected with virus. When i connect the S2 to my pc, it is detected in My Computer but it will displays all the folders. So i took a back up of all the images that are saved in my phone memory to an external SD card. Now i want to format my phone and restore all the data so that the virus would be cleaned. So please help me how can i do properly so that i would not loose this phone.
My phone version :
PDA : I9100XWKE1
Phone : I9100NEKD5
CSC : I9100H3GKD4
Thanks.
I have the t mobile galaxy s2 and cannot figure out how to successfully change the boot animation. I have tried multiple ways and can’t get it. I’m on the Juggernaut 4.1 ROM with the new Darkside kernel.
I have the U+ S2 from when I lived in Korea. It is a CDMA phone and doesn’t have a sim card.
I am wondering if I can root the phone using your site or if I am out of luck.
Any and all help will be appreciated.

Hey Max, can you do a review on the T-989 Samsung Galaxy S II “Revenge of Macnut”?
http://forum.xda-developers.com/showthread.php?t=1483004
Its really cool!
I have a Samsung Galaxy S 2 LTE from NTT Docomo. I used your “How to Root Galaxy S2!” before and it worked flawlessly. There was a recent update on the Gingerbread to SC03DOMLB2. I need to re-root my phone now, but your directions no longer work. I re-downloaded GalaxyS2RootNew.zip and tried again, but it still wouldn’t work. Can you give me any advice?

You guys ROCK! Your site and videos are excellent. Where do I sign up for the weekly newsletter?
Hi
Thanks for your marvellous website and You Tube demos.
I have rooted my Galaxy SII 9001T according you your instructions and, as far as I can tell, the phone has been rooted (i.e. I can use Titanium Back-up, CWM and Rom Manager). I also get the Yellow Triangle. However…
1.The Superuser Icon has NOT turned into a scull as most sites suggest (but it does shows the above mentioned apps have been opened)
2. When I now try to boot into download mode, it seems to boot to CWM mode instead, preceeded by some (yellow text) saying —Copying Media files etc, updating application etc, successfully applied multi-CSC. Eventually, blue text is added, allowing me to choose to reboot, wipesata/factory set, wipe cache or download from SD card. (I can also boot to a download sceen via ROM Manager or CWM, but that shows a screen different from the original). It has a large Android symbol in the middle of the screen with the words “Downloading… Do not turn off target!!”. No other text on the screen.
3. when I navigate to the download menu (in the CWM screen) and try to flash a ROM (I have tried both the Resurrection Remix or MIUI ICS) it starts with the word “installation..”, but soon after it reverts back to the menu saying that the “E:Signature verification failed”.
Some advise will be greatly appreciated, thanks.
Best regards
Jorgen Hansen
Hi
Further to my previous post, disaster struck! As I wasn’t sure if CWM had been installed properly, I followed the instructions herein and it SEEMED to go through ok. However, the phone now only boots to the yellow triangle stage and then hangs!
I’m able to boot into the CWM (which now seems to be installed correctly!) (but NOT into the Download screen), but it tells me that it is unable to mount anything in the Cache. Attempts to mount the different items in the “Mounts” menu, all results in error messages.
Can anyone help, PLEASE!!!!
Odin back to stock and start from scratch.
Also in the rom installation menu in CWM recovery toggle the option to turn signature verification off, if it is enabled, you will not be able to flash a custom rom.
Anytime phone is stuck at any point looping or unable to get into recovery to wipe data and reflash, ALWAYS just odin back to stock and reroot. it’ll only take 15 minutes
Anthony M. McAfee
Hi Anthony.
I just want to thank you for your kind reply. I managed to get the phone working just after writing and I only just now returned to the site.
I have since successfully rooted the phone and have already tried many different roms.
Once again, thank you for your help.
Do you have a video on how to install theesurrection Remix ICS ROM v9.7
Thanks
I would love to subscribe to your email list, but unfortunately, there’s nowhere to do so on your site…
if you post a page with that option, or I’m missing something, please let me know so i can get my email on that list.
Thanks!

your new way of rooting looks great using the .bat file but can not be used with mac heard you were going to do a mac version?? have you done this, could not find it? not sure about the whole rooting thing so when i saw your new way of rooting i was very interested because of the easy (idiot proof) for people like me. thank you
Max, your videos and tutorials are all great, but if you read through the comments you’ll see that many people who try to install the custom roms have a terrible time with the phone looping at startup. This happened to me even though I followed your directions step-by-step with the video. Can you please address this problem, or perhaps even make a video showing us what to do if this happens and how to resolve the problem? Thank you.
hi max. i own a gs2 i9100. i installed the resurrection remix 9.6 rom. but then i couldn’t get to the clockworkmod recovery for backing up my rom. So i watched your video on how to install clockworkmod on s2. i didn’t know it was for gingerbread so accidentally flashed the .tar file. now i cannot start my phone. I haven’t backed up my files or roms. what should i do. please help. thanks
i have an international galaxy s2…works great but i cannot get on tmobile’s 4g network…clearly the s2 works on their network. my question is, if i install a tmobile rom, will i be able to get access to the 4g network at that point? if so, how? which video ?
Everytime i open s2 Root.. it hangs, and i dont know what do do with it anymore..
I watched your video on how to install ClockworkMod Recovery and did that successfully, i then bought a USB jig off Amazon for Samsung galaxy s2 i9100. Plugged it in the bottom and it entered download mode but didnt reset the download counter just sat there like i had entered download mode without any jig.
So any idea where i have gone wrong?
Samsung s2 i9100
version 2.3.4
kernel 2.6.35.7-01045-g551a073-dirtycodeworkx@cyanogenmod #4
build number GINGERBREAD.XWKI4
how can i get cyanogenmod 7 on galaxy s11 t989?
How about a review on the TURKBEY v5 Rom (ICS)? It seems to be as stable as the Resurrection Remix rom and it is very good looking.
First off, I coundn’t thank you enough for all the information you have on this website. I travel a lot and rooting my phone has helped with the tethering option that ATT had blocked. I have rooted my Samsung Galaxy S2 from ATT as in your video. I also installed Titanium Backup and uninstalled the tetheringmanager. When I use the tether hotspot it works fine with my laptop but somehow it does not work with my ipad. It says connected to WIFI but when I try to surf I get a message stating “unable to receive response from server” and advise.
First thank you for your services. I am wondering how to use galaxy2newroot using a MAC. Could you assist? I can not seem to locate a MAC procedure/downloads for the Galaxy S II international phone I9100 (I9100XWKE1)
I don’t know if you can help me on this issue but I am just going to ask
My galaxy s2 model-GT-I9100 has gone to a black screen i cant do anything it charges and you can hear it turning on but stays on black screen. I have tried soft reset and Samsung people don’t know what to do.
I am hoping one of you know how to resolve the display issue.
i have a question?can i install sgs2 at&t rooms on sgs2 tmobile …i have a sgs2 from tmobile….
I have stock ICS on my i777, installed through the method on this site. How can I root now that I have ICS? I can’t use that same kernel that’s for gingerbread, right?
How do I subscribe here?
Is there a way i can unroot my i9100 to stock gingerbread? and by stock ics, do you mean the one that google made and launched for specific countries?
Hi friendsd. I am a fanatic of your web site. I have a AT&T SGS2 and today finally intent to “open” my phone to install one of your recomended ROM. I use de CM method to chance the Recovery Bootloader due to the original, all the time request a permission to open any zip files, and no access to a System/csc/…
All the issues doing well and install the ClockworkMod Recovery as well. Later installed a Zedomax Kernel to test if I can install a ROM and appear the Yellow Triangle in the screen without any action…It is dead.. Any recomendation…Help please
You should really evaluate the Dragon ROM for the s2. The release today is based on milestone5 and the roms seem to be as good if not better than resurrection… http://forum.xda-developers.com/showthread.php?t=1457061
Downloading to test this latest release myself. Love your reviews but think this ROM deserves a place on your site…
ics 9.6 have no fm radio.Please provide radio
I am trying to root and possibly upgrade from 2.3.6 to ICS on my galaxy S2 GT9100G, but all information I can find are only for 9100. I have attempted to root using the safe method you mentioned but does not work. Anyone have any idea? Hope you guys can post some videos with the GT9100G version
[Q] Please Help me!!
I tried to wipe everything off my phone. I booted into Clock recovery. This is what I did: Wipe data/factory reset
wipe cache partition
Wipe Dalvik cache
Format /data
format /system
format /cache
format /emmc
format /sdcard
Because I want to get rid of everything inside my phone and then I sell it to someone.
I downloaded some roms and put it into my sd card. But obviously, what I get is “Couldn’t open directory. No files found”
I tried backup and restore and install zip from sdcard. But the result is the same.
My phone(Galaxy s2 t989) is rooted
I think I screw everything up
Please help I would really appreciate it.
Hi my friend:

Thank you very much!!!
Hi, I was just wondering how come you don’t post any roms for the att sgs2 skyrocket?
I’ve heard that you could sometimes use T-mobiles roms and if so how do go about doing that?
Thanks in advance

Hi ! I’d like to subscribe but I don’t know how.
hi,
I had gs2 with gingearbread, but then i rooted it, using the zyrgeling method, installed clockwork recovery and ics. It worked fine, but not great, so i changed the rom to one that was not compatible, and then, instead off changing it back, i rooted it again but using the way for ics, the device rebooted, but didn’t load, and it’s not loading since.
The worst part is that i didn’t back it up. I really hope you can help me.
Thanks
What’s the point of this page if your not going to respond to anyone’s post??
Hello friend, I want to ask a huge favor from come grab one month on reading and reading updates to ICS and last week I dared, I do with Odin but not if it does one good my team is a sansung IBS, now my machine hangs or turns itself off and marks in most applications: fault, I would appreciate if you help me know what happened do wrong and if I can solve.
Hey I have been using your website for a while now with great success as far a rooting goes. recently I took things a step further and seemed to have done some damage to my phone in the process. I was wondering if there is any way that you could tell me how to get it working again, if of course I told you the symptomology. Im a total newb at all of this and should not have been playing around with the custom ROM stuff. Thanks for any help you can give me.
