HD7 vibrates 7 times, gold card fails
I bought an HD7 from UK with a broken screen. Just installed the screen, and tried to switch on the phone for the first time. It was stuck on the HTC logo. So I pulled the battery out, and tried to reboot, but now it vibrates 7 times and does nothing more.
BTW. I made it to boot into bootloader, and it shows the attached screen.
I tried to flash a stock NoDo rom with GoldCard, but it fails at the first step, saying:
"Radio.nbh - FAILED"
I've used the GoldCard on two other HD7s in the past, so I guess the problem lies elsewhere. Now I try to download an other original O2 UK rom, and see it it makes any differen or not.
Any clue about what could cause this? And how to resolve the problem?
