The rootability of the HTC Thunderbolt continues to reveal more gems as as XDA Moderator CaptainKrtek, with support from NetForce-TX, has created a one click method which, after testing, is pretty easy to apply. The method is a Windows batch file which runs the user through the complete process and ends with a rooted Thunderbolt ready to play with. CaptainKrtek suggests users still give the thread a good solid read just in case anything goes wrong, but he's confident that, thanks to NetForce-TX's testing, that the batch file is sound and works as advertised.
This is a simple batch file that will guide you in rooting your device. It is pretty easy to follow along but please take your time and read everything.
The root batch program requires that the Thunderbolt be running 605.6 or 605.9 firmware and needs to have drivers, SDK, exploits and a few other things installed. All files are available in from links in the main thread and it's important to remember that users are on their own and it will void your warranty. CaptainKrtek will answer questions on the thread itself, but will not offer to help root personally. So properly warned ye be.
So far, the reaction is success across the board, with hopes of a Linux version forthcoming. There's also a few manual steps that users found like setting the phone into debug mode to mount the ROMS. Should anything go awry, however, CaptainKrtrek suggests unrooting and starting over per this thread.
