Today my D3 rebooted unexpectedly. After the reboot, the phone didn't turn on, and I connected to energy to make sure that it wasn't a battery problem. When I connected it, it tried to boot, and I left it, but when I came back, the phone was fully dead. Doesn't turn on. The battery is OK, I put it on a Motorola Bravo, and it showed 60% charge. I have a Factory Programming Cable, and I connected it to the phone, but neither this way the phone did turn on.
I don't know what to do, it seems that is a hardware problem . When I put the battery, the phone heats a lot
