Default Stuck power switcher

I left my AT&T HOX+ charging overnight and, when I woke up, it was infinitely rebooting. I thought I should just try to boot into recovery and flash the ROM again (I'm using MagioROM R1.1).

When I tried to enter on recovery mode, I wasn't able to select the options and it selected the first ones by itself.

"Tada, it's the power button!" I thought. Opened the housing and it keeps restarting. Problem: power switcher.

Has anyone had this problem? How am I supposed to fix it?

No, I can't send it to the support, once I live in Brazil and there's no HTC support here
