HTC One X stuck on "quietly brilliant screen", stock phone, can't factory reset

Hi everyone,

Tried to restart my phone today. Then it got stuck on the quietly brilliant screen, so I tried to clear cache and go into recover mode through the hardware keys, but the screen with the exclamation mark showed up. So I tried to factory reset the phone. The exclamation mark showed up again, and now it's stuck on the quietly brilliant screen again. Any ideas? My phone is stock, never rooted it or anything.
