i have to have the worst luck in the world.. got my nexus one today. condition is MINT. seller also included the receipt from HTC proving that it got replaced. popped in my sim, everything worked fine. turned it off to swap batteries and thats when the hell started. im not able to get past the nexus logo. NOTHING. it would turn on, than go to the screen, vibrate, than repeat multiple times. phone has never been rooted. i did EVERYTHING. i did the volume down plus power and than i cleared wiped the memory, same result. than i tried downloading 2.2.1, renaming it to update.zip, put it on my zip, but that doesnt work. the phone can't tell theres a update. like **** man. i than went here Nexus One/Guides & Tutorials - XDA-Developers read that i needed FRG33 and rename it to PASSIMG.ZIP. when the phone turns on, it gives me the message if i want to update, i get excited. i click yes, everything says ok, than i reboot and bam, still endless reboot. tried to do the passimg again but this time i get a fail on radio V2 or something like that. WTF is going on. i didnt do anything. ANYBODY HELP?
