For those of you who want to root your Galaxy S2 GT-i9100 on Jelly Bean Android 4.1.1 orAndroid 4.1.2, heres how to do it easily using a custom kernel.

This rooting process is pretty safe to do, does not erase anything on your phone, it justinstalls a custom kernel (which comes with a custom recovery) and we root the phone usingSU binary and Superuser app. Thats it!

Step 1. Turn your Galaxy S2 GT-i9100 off. Then hold down Volume Down, Center Home,and Power buttons together for about 3 seconds until you see the warning screen.

Step 2. Hit Volume Up (you will be in ODIN Download mode) then connect a micro-USBcable from your Galaxy S2 to your computer.


2 of 43 8/18/2013 4:31 PM

Step 3. Download Jeboo Kernel and ODIN package. Leave the kernel file in .tar format butunzip (Dont have unzipping program? Download and install 7Zip.) the ODIN zip files.Download kernel:

Download ODIN:

3 of 43 8/18/2013 4:31 PM

Step 4. Run ODIN3v1.85.exe by double-clicking on it. If you dont see a yellow highlightedbox with a random COM number, download and install Samsung USB Drivers.

Next, DONT TOUCH ANYTHING ELSE but hit the PDA button.

Step 5. Choose the Jeboo kernel .tar file you downloaded earlier.


4 of 43 8/18/2013 4:31 PM

Step 6. Hit the Start button and this will start flashing the kernel. Once it says PASS!your Galaxy S2 GT-i9100 should reboot.

Step 7. Once rebooted, download Superuser zip file straight to your phone or you canalso copy it over from your computer.

Step 8. Turn your phone again then hold down Volume Up, Center Home, and Powerbuttons together for about 20 seconds until your phone reboots into CWM Recovery.


5 of 43 8/18/2013 4:31 PM

Step 9. Choose Install Zip.


6 of 43 8/18/2013 4:31 PM

Step 10. Choose Choose zip from Internal sdcard or Choose zip from sdcard.(Depending on where the Superuser zip file is)


7 of 43 8/18/2013 4:31 PM

Step 11. Find the Superuser zip file, its most likely in your download folder.


8 of 43 8/18/2013 4:31 PM

CWM-SuperSU-v0.99.zip if your super user zip file.

Step 12. Installing this file installs su binary and Superuser app to your Galaxy S2


9 of 43 8/18/2013 4:31 PM

GT-i9100, giving you full root access.

Reboot and you should find yourself with a SuperSU super user app.

You can download rooted apps like Titanium Backup app and get a super user pop upwindow when you try to run it for the first time. Congratulations! Youve rooted your GalaxyS2 GT-i9100!!!

Lee says:March 22, 2013 at 1:44 pm

Download and install Cygwin, navigate to where the zImage file is stored using the cdcommand and run the following:

tar -H ustar -c zImage >> jeboo_kernel.tar

This will create a .tar file that can be flashed with Odin. Hope that helps

Guys, just wanted to let you know that this method worked perfectly on my GS2.I was desparate to finally move from ICS 4.0.3 to JB 4.1.2 (XWLSD), but I had to backup all my appsdata using Tytanium Backup.I watched several other methods that involves installing multiple untrustful apps, backing up lots of stuff,etc, etc, etc. But your method is clean and safe.My GS2 running JB says thank you from Brazil!

nickc says:February 22, 2013 at 11:22 am

Figured out how to restore the Kernel. After extracting it, it needs to be tard in the correct way.Used an ubuntu live cd because linux is useful (almost required) Used instructions here:

Hi, not sure if this will be replied or not, but here we go.Since I rooted my samsung galaxy s2, I have had problems with my headset. Other headset apps wontwork and upon pressing the button on the headset, it gives the wrong command (skipping to next trackinstead of stopping/playing). Has anyone encountered a problem on this and can help?

After spending time at xda-developers site I was guided to the answer (thanks, brandonarev). You candownload framaroot, which works on I777, no matter what Android you are on. http://forum.xda-developers.com/showthread.php?t=2130276 Would suggest you download ROM Manager afterwardand grant yourself SuperUser privileges. I downloaded the AJK kernel for I777 running 4.1.2http://forum.xda-developers.com/showthread.php?t=2110542.

Installation is easy:1. Download ROM Manager from Google store


37 of 43 8/18/2013 4:31 PM

2. Download framaroot.zip to your phone3. Pull down the notification bar and press it to let it install. When it comes up, select Superusersu,Aragorn, and let it install4. Start ROM Manager and let it install (also installs Clockworkmanager recovery, now that you arerooted.

New Kernel3. Download the AJK zip file to your phone and confirm its location4. In ROM Manager, set Reboot to Recovery Mode5. Reboot. Enter ROM Manager, wipe cache partition, backup, hit advanced and wipe Dalvic (sic?)cache6. Back to top menu, Install zip file, and then it lets you navigate to where you have stored it.7. Select the AJK zip file and install it.

You are now rooted and running the AJK kernel.
