Samsung Galaxy S II has already been risen out to shine on tech horizons and it has been rooted too by Chainfire at XDA Developer Forum. It adds Samsung Galaxy S II to the list of 3rd-party developer unlocked devices. Now, PocketNow reports that the Superuser access has been attained with the help of Samsung flashing utility “Odin” to load a custom re-packaged kernel onto handset, then booting up. Once booted, the kernel lets root access via the “adb” program that is a part of the Android SDK. Just type “adb root” at the command line restarts adb in root mode, and lets full system access through “adb shell”.
The report further explains that the full root access attained by this technique is temporarily, yet you can turn it to a permanent superuser access by following some steps including manual loading of su, busybox, and Superuser.apk. It ios worthy to note that Chainfire successfully managed to re-package this modified kernel by using methods efficient on the Galaxy S series of devices, requiring no orignal SGS II to develop/test with.
Samsung’s Galaxy S II is, no doubt, the most elegant and superb phone that is getting extreme popularity day by day due to its very startling hardware specs with a cute 4.3inch Super AMOLED display.
If you are also willing to root your Samsung Galaxy S II on Android 2.3.3,here is a how to guide for your kind pleasure;
It is rather easy if you know the drill from other Galaxy devices, but if you are a complete beginner with Samsung phones or Android in general, please read very closely! Try to remember what you do, as likely in the future you’ll be using ODIN more often, to flash custom kernels, custom/leaked firmwares, etc.
Quick guide (for experienced users)
- Reboot into download mode
- Using the attached Odin version, flash the attached XWKDD kernel as PDA. Do not use the PIT, do not have any options checked except for “Auto reboot” and “F. Reset Time”
- Wait for the device to reboot
- Use the “adb root” command to restart ADB in root mode, followed by “adb shell” to get a rooted shell; then you can manually push Superuser.apk / su, busybox, OR use SuperOneClick to finish the job for you.Long guide (for beginners)
- Download the attached ODIN file and extract the .zip file
- Download the attached XWKDD, but do NOT extract the .tar file
