Root Methods:

1.) The adb method works and helps you understand the process.


2.) The Easy Rooter Works great as well and requires less steps and knowledge of what you are doing.


3.)One Click Method For PC, which also works quite well.


4.)Easy Root Mac/Linux Version If you are on a Mac or use Linux

I have tried each of the PC versions and rooted and unrooted my Thunderbolt quite a few times now, to help test different methods.
Once you use the Easy Rooter method, yes it downgrades the firmware during the process.
This firmware(rom) is not what you are supposed to stick with using.
Although yes, it does function just fine.

After the downgrade and rooting, there is a simple step to:
use Rom Manager and CWM(ClockworkMod Recovery) to flash a recovery image,
which then upgrades the firmware to the same revision that the device shipped with.
Or you can then flash any of the custom roms available.

Also, yes there is a way to unroot as well.

[WARNING] Do not downgrade to 1.0xxxxx after root
