Hello! I have a Desire HD that is stuck at the Hboot, no recovery or anything.
I managed to flash some ROMs, either through Hboot or RUU but even then, the phone stays stuck at Hboot.
I tried many official ROMs and RUUs. The ones that can be flashed succesfully are the main zip from this thread (WWE Stock Rom) and the two Sense 3.0 WWE RUUs.
The update process seems to proceed fine, but at the end, when I reboot the device, it gives me 7 vibrations at the white HTC screen, then the screen goes black and stays stuck for ever (or at least for 2 hours).
I do not know much about the device, only that it had a custom rom and one day this happened.
If you have any suggestions or ideas, I'd be glad to hear. Even some generic (short) answers will do if you have any idea at all.
HTC service says that because of the custom software, the phone isn't anymore under warranty and they need to replace the motherboard.
