My brother's Droid1 has died after applying the 2.2 update OTA. He bought the phone off of a friend so there is no support from Verizon on this. The phone has never been rooted or messed with at all. The phone was fine running stock 2.1 for months (the 2.1 update came OTA too). He was prompted to update the phone to 2.2, which he accepted. Since the update was applied, the phone was freezing up randomly and would require a battery pull to get it back. One day it froze and after a battery pull, the phone sat at the M logo and wouldn't boot.
I took a look at it and the phone can still get to the bootloader by holding d-pad up. Using the information on this and other forums, I downloaded the stock 2.0.1 .sbf and used RSD lite to flash the phone "back to stock" successfully. When the phone is to reboot though, it goes right back to the M logo and stays there. I can get into the bootloader as many times as I want, and I've flashed the stock .sbf's of 2.0.1, 2.1 and even 2.2 to no avail. Any suggestions? Thanks in advance.
