The folks at Android Police have leaked a Gingerbread build for the HTC Thunderbolt It’s version 2.11.605.2, but as always we’re unsure as to what’s different between this and any previous leaks. We do know that it keeps users on HTC Sense 2.1, but that was to be expected. This is an unrooted RUU file, meaning rooted users may want to wait until developers of their favorite ROMs incorporate the update. For those who aren’t rooted and want to give it a shot, be sure to download the file here and follow the instructions below.
- Rename the file to “PG05IMG.zip” (without quotes)
- Drop it on the root of your SD Card
- Turn off your device
- Hold Volume Down + Power to reboot into the bootloader — the file should automatically be detected and the flashing process will begin.
- Wait for your device to complete the process and reboot
