The metal shielding was causing issue with starting the device. Probably it shorted some capacitors on the edge of the board.
USB still doesn't work. It has power (checked with multimeter), but the lights on keyboard don't turn on.
Last time I've made a silly troubleshooting move. Because I couldn't get into safe mode,I've defaulted safe mode startup while being connected via remote control. Of course wifi doesn't work in safe mode, so now I cannot use the device whatsoever. Is there any trick I can get wifi to work or to make default boot back to normal (without mouse/keyboard)?
