mobile

Stock DNA, never rooted, never s-off. Fell asleep and woke back up with phone in quietly brilliant bootloop. Went into boot loader, cannot access recovery(just bootloops), can't do factory reset(just freezes and have to reboot) . Downloaded and followed all necessary steps to use adb and reboot recovery, when typing adb devices it shows up blank, but when I do fast boot devices my serial number comes up. When in fast boot on the phone it says fast boot USB how it should. As of lately the bottom 3 buttons are starting to flash when holding down power button, before they didn't. Also when I plug it into the wall it never showed the battery icon actually charging, but now it does, when it gets to a certain % it turns itself on and bootloops. What to do what to do??
