Hello, I just bought a second-hand yet "good quality" HTC Desire and it's boot-looping at the HTC logo screen but starting up with no problems sometimes. It was also randomly shutting off when I first started using it, although this hasn't happened in a while. I have very little technical knowledge of mobiles, but it seems people are posting the information on the hboot screen here, so if this helps: BRAVO PVT4 SHIP S-ON HBOOT-0.093.0001 MICROP-051d TOUCH PANEL-SYTN0101 RADIO-5.10.05.30 Aug 10 2010, 17:52:18 The seller is suggesting this may be a battery problem, but is also offering a replacement. Advice/fix would really be helpful. Thanks!
