[Leak] Android 4.1.1 Jelly Bean build for T-Mobile’s Galaxy S III out in the wild

Great news for T-Mobile Galaxy S III owners! The Jelly Bean update you all have been waiting for is finally here. While it didn’t officially come from Samsung, you will still be able to load it onto your handset. In order to successfully achieve that, you have run stock or simply go back to it before flashing the new ROM. The good people at XDA have posted the following step-by-step instructions:

  1. Download and install stock (if you are not already on stock rom) This is needed as a base. The update will otherwise fail
  2. Download OTA
  3. Apply zip in recovery menu
  4. Enjoy Jelly Bean 4.1.1

Folks who flashed the ROM are reporting bugs and reboots meaning that this isn’t the final build. If you do encounter any issues, make sure you do a factory reset along with some cache clearing and then try it again. Let us know how it works out for you.
