Root AT&T’s Samsung Galaxy S2/SGS2
AT&T’s version of the Samsung Galaxy S II has no major difference compared to its European sibling. The handset packs a 4.3-inch Super-AMOLED+ display, and is powered by the same Exynos 4210 chipset. The only difference is that the AT&T’s version lacks a physical home button, and instead uses four standard capacitive Android buttons.
Please read this before rooting your AT&T’s Samsung Galaxy S II -
After flashing a custom kernel on the Galaxy S II, a small exclamation mark will be shown every time the phone is rooted. This happens because the Galaxy S II has a custom counter, which keeps a track of how many times a user has flashed a custom kernel on his phone. The only way to remove this exclamation work is to use a USB JIG, which resets the custom counter to 0.
AT&T’s version of the Samsung Galaxy S II is same as the European version (I9100) of the Galaxy S II, except that it has four capacitive keys instead of the one physical home button, and two capacitive keys.
The guide below will work for AT&T Galaxy S2 running Android 2.3 Gingerbread as well as Android 4.0 Ice Cream Sandwich
Below are the steps to root the AT&T Samsung Galaxy S II -:
- First of all, users need to download ODIN to flash the pre-rooted kernel on their handset. ODIN can be downloaded from here (v1.85).
- The pre-rooted kernel along with the system package can be downloaded from here. If your AT&T Galaxy S2 is running Ice Cream Sandwich, download this (Mirror) pre-rooted LE5 firmware system package.
- If you have not already installed KIES, please do so. It will automatically install all the required USB drivers. KIES can be downloaded from here.
- Extract ODIN from inside the rar file, in a new folder on your Desktop.
- After this, start ODIN and click on the PDA button. Select the pre-rooted kernel which you downloaded on Step 2. Keep in mind that the pre-rooted kernel and/or the rooted system package which you select should always end with a .tar extension.
- Boot your Galaxy S II in Download mode. To do so, power off the device and remove its battery. Put the battery back in, and press the Volume Down + Power Key simultaneously. Press the Volume Up button when your phone gives you a warning about a custom OS.
- Once the phone boots into the Download mode, it will show an Android logo with “Downloading…” written below it. Connect it to your computer, and ODIN will automatically detect your phone, and the COM box will glow in yellow. Do NOT change any setting in ODIN.
- When the phone is detected, press the Start button and wait for the tool to flash the pre-rooted kernel on your handset.
- Your Galaxy S II will automatically restart, and you will have root access on your handset!
