So I rooted my Thunderbolt and unlocked the bootloader. I had Das-Bamf 2.0-5 running and decided to go back to stock. I followed the instructions on XDA on how to revert back to stock OS but I decided to not flash back the bootloader incase I needed it to be open for something. Will I need to flash the bootloader to S-ON so that I can receive any future updates from Verizon and not brick my phone?
