How to Root Android 4.0 UVLE1 Firmware on T-Mobile Galaxy S2

  1. Make sure your phone is on the Android 4.0 UVLE1 firmware. You can follow the guide here to flash UVLE1.
  2. Make sure you have the phone drivers installed on the computer. If not, download and install them from the link below.
    Download Drivers
  3. Download the root file.
    Download Link  |  Filename: Root.zip
  4. Copy the Root.zip file to the internal SD card on the phone. Copy the file itself, do not extract its contents.
  5. Download the Clockworkmod touch recovery file.
    Download Link  |  Filename: recovery.tar.md5
  6. Download Odin which will be used to flash the recovery on your phone.
    Download Link  |  Filename: Odin3 v1.83.exe
  7. Open Odin by double-clicking the Odin3 v1.83.exe file downloaded in step 6.
  8. Switch off your phone. Then, boot into download mode. To do this, turn off your phone. Plug in your USB cable to the computer, but not to the phone. Then, holding the Volume Up and Volume Down buttons on the phone, plug in the USB cable to the phone while holding those buttons. Once the Download mode screen shows up, let go of the buttons.
  9. After you connect the phone in download mode, you’ll notice Added!! message in Odin’s message box in the bottom left. If you don’t get the message, check that the drivers are properly installed and start from step 7 again.
  10. Now, in Odin, click the PDA button and select the .md5 file you got in step 5 — recovery.tar.md5.
  11. Important! Do not touch any other button or make any other changes in Odin except selecting the required file as given in step 9.
  12. Click the Start button in Odin to flash the Clockworkmod Touch recovery on your phone.
  13. Now, hit the START button to start flashing the recovery on your phone. When the flashing is complete, your phone will automatically reboot — and when you see the Samsung logo, you can safely unplug the cable. Plus, you’ll get a PASS message (with green background) in the left-most box at the very top of Odin. What to do if Odin gets stuck: If ODIN gets stuck and doesn’t seem to be doing anything, or you get a FAIL message (with red background) in ODIN, disconnect the phone from the PC, close ODIN, remove battery, re-insert it, then repeat the procedure from step 7.
  14. After the phone boots up, turn it off. Then, press and hold Volume Down + Volume Up + Power keys together till the screen turns on, to enter ClockworkMod recovery.
  15. Select install zip from sdcard, then select choose zip from sdcard. Scroll to the Root.zip file on the SD card and select it. Confirm installation by selecting Yes – Install Root.zip on the next screen.
  16. After the installation is complete, select go back then select reboot system now to reboot the phone.

  • CatatonicBug

    I went through the steps and everything seems to have worked, but I still can’t write to the root directory on the phone! Apps like Titanium Backup install and run just fine, but I still cannot paste a file into the root directory on the phone.

  • Kyle

  • D

    My penis got bigger after upgarde this root works yesss!!!

  • Deborah

    OK. Just figured out I had to swipe down in CWM to choose “yes” to confirm the install of root.zip since it didn’t appear on the initial screen. Duh. Appears to work fine. Seems a tad slower. Will down load titanium backup to weed out some junk apps. Will post again if I note anything else. Thanks!

  • Deborah

    When I select root.zip, the confirm screen doesn’t offer a “yes option” only a column of “no’s”, so nothing gets done. Basically still have the stock 4.0 after flashing the recovery.tar.md5 – I had updated an out of the box phone to 4.0, with no customization or sim using Kies before trying the root.

  • nef

    Perfection! Thanks

    It’s touch recovery; use the touch screen instead of hard buttons. Worked for me that way.

  • JEFF

    Same thing here, boot loop! PLEASE HELP!

  • 4235435

    Same here, CMW goes into a boot loop.

  • sjs

    Same, CMW goes into a loop, shows all the “menu options” such as install from sdcard however, the on/off key which usually chooses the menu option does not work and the main menu here just flashes on and off.

  • randomuser1223
