UPDATE: The Gingerbread radio is apparently being linked to hard bricks. We have removed the link for the time being, until this issue is resolved, or a new radio version is leaked.
This morning 911Sniper dropped a leaked Gingerbread test build for the HTC Thunderbolt, but there was one issue: it wasn't flashable. Our buddy Justin Case from TeamAndIRC immediately took it to the lab and started dissecting its parts to see what needed to be done. When he returned, blood soaked and sweating, he delivered an amazing thing to us - a working Gingerbread ROM. Flashable, functional, and near-official, we offer this to you as download.

HTC tried to stop us. They made signed images, a signed kernel, and a signed recovery. They locked the memory. In short, the ThunderBolt is their most locked-down phone to date.
We fixed it for you. Unlike the root method we described yesterday, following the instructions below will provide S-OFF, remove signature checks, and unlock eMMC. Enjoy!
Rooting The ThunderBolt - Version 2.5
Update: This guide was updated to include some steps into the upgrade RUU, making it faster and safer
- Root with read/write access to /system
- Ability to downgrade and flash any RUU (i.e. signed firmware)
- Fully unlocked bootloader
- All ThunderBolts survived testing
The method of rooting your Android device as described in the article herein is solely for enthusiasts and not for the faint of heart.
