Phone won't charge or reboot

My phone overheated and tried to reboot itself and froze on a reboot loop so I factory reset it. Then the next day it overheated again and started flashing on the reboot screen again. I left the battery out and let it cool off and tried to turn it on again with the same issue of the screen flashing. Now it won't turn on or charge and I've already tried the volume up+ power+ home button combo to try to factory reset it again. Is there away to fix it or is getting a new phone the only option?
