Hi all, I have an HTC Desire bought in July 2010. I did not use it for the last six months. Tried using it yesterday after charging and the phone will not boot, when I press power, it vibrates once and then after a couple of seconds another 5 or 6 times, and then is stuck in the boot with a small circle indicator. I tried to reset to factory default by the volume down + power button method many times, with and without SIM and SD cards, no luck. The phone is not rooted. Does anyone have any advice? Thanks in advance.
