Same thing happend to me, Its just vibrates, show me the Nokia logo and reboots over and over and over again untill i remove the battery.
I was thinking about flashing the phone, thing is: When i plug it to a chager (PC and/or wall charger), it turns on, and keep rebooting like someone is paying it to do so. And my battery aint fully charged.(dont have a spare one), and the phone wont charge.

So if i try to flash it with the rest of my battery life, it migth go very bad if i run out of juice. and my guess would be that since the phone just wont stop rebooting while connected to Chager/PC, it migth scew up the flasing?

EDIT: Not same as the OP's problem, cause his phone seems to boot up to the desktop, while mine never gets passed the Nokia boot logo.
