It's been a while since VZW showed any love to Thunderbolt owners, but that doesn't mean that it has forgotten about them completely. In fact, we just received a leak of a new build that brings some fixes and enhancements to Big Red's first LTE device.

Download and Flash

Disclaimer: Android Police isn't responsible for any harm to your device - proceed at your own risk.
If you unlocked your phone with the official HTC unlock tool, you will need to re-lock in order to flash this!

First things first, you're going to need the download.

Once that's finished, here's how to flash it:

Update: The RUU also includes a new radio.

CAP201204171511

This is a full RUU, so it will completely wipe your phone.
  • After downloading it, rename it to "PG05IMG.zip"  Note: If you're doing this from a Windows machine, make sure you don't rename the file "PG05IMG.zip.zip," as Windows hides known file extensions by default.
  • Drop the file on the root of the 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

...and you're done. Let us know how it goes in the comments. Enjoy!

Thanks, Jack the Rapper!
