The best part is the process to get there, it was as easy as
- Install the correct ADB drivers on your laptop (available within the same zip file from dalepl)
- Connect the Thrive to the laptop via USB mini and ensure it is connected to the charger at the same time.
- Run the batch file Universal_Easy_Flash_Tool.bat
Confirm the fact that you want to root the device...
And pick the correct ROM that you are currently on...
And after about 4 reboots of the device - you are done!
