I'm currently using a t-mobile stock HTC One. My phone randomly got stuck in the boot up screen so I went into boot loader and powered the phone down. Powered it back up and same thing. So I went into boot loader and tried to go into recovery mode. I saw the red ! but didn't know what to do so I hit the power button and the screen went black. Nothing is working now and when I plug the phone into a charger, nothing happens. Does anybody know what to do?
