so i decided to download a game on my vita through the vita itself and i thought the vita would download while in sleep mode. then good while later i tried to turn it on but it wouldnt odd since it had a good amount of battery left but either way i plugged into a charger and restarted it thinking the download being only around 3 gigs was already done. then to my surprise the download was paused. i tried resuming but the console crashed when i did that. then i tried to cancel and restart the download. it still crashed. now it seems to crash inevitably no matter what i do. after a few restarts it also started to display an error that it wasnt turned off properly then crashing very shortly afterwards. what do i do to fix this?
