My Nexus One die after update to 2.2 via OTA

I was expecting to receive update notice for whole week...but it just the beginning of my nightmare.

I just followed the instructions and Android Robot appear on the screen.

Then, it restart and show four colors "X"


And always "X" for 1.5 hours

I tried to remove the battery and restart again but it just shown "X"

I've searched suggestions on internet and entered to HBoot for factory reset

it's still die there...

It has been announced for over 7 weeks but still be sold in 4 countries only! In the meantime, HTC, the ODM manufacturer of Nexus One, announced HTC Desire in MWC 2010 and it has similar Spec. with Nexus One. Moreover, HTC Desire has Sense UI and trackpad and it'll be "broadly available" throughout Europe and Asia in the early part of the second quarter...

Yes we have heard some problems about 3G connection but it can not be solved for such long time?????
