So I received a replacement X and i need to send the defective one back. Problem is, I updated to the OTA 2.2 on the defective phone and it was rooted, and remained rooted after I updated. I rooted with one click root on Windows. I tried to unroot it using the same program and Superuser Permission still stayed in my app drawer even after a factory reset. Basically it unrooted but left the Superuser Permission app on my phone. I decided to try to flash the SBF to go back to stock 2.1 and it bricked my phone. I'm stuck in the boatloader and it will not reboot, or boot into recovery mode. PLEASE SOMEONE HELP, I NEED TO UNBRICK THIS PHONE AND NOT VOID MY WARRANTY.
