try to reinstall 8.1 upgrade
this is what happened to me when i upgraded to 8.1
hi , 1st attempted the update with the new (2nd ver. correcting the erasing error) see <https://twitter.com/BoyueTechnology/status/1298807003393847296>
my first time it loaded the firmware 100% rebooted 1 black screen erased then jumped to reboot then got stuck in a rebooting loop.I almost had a heart attack
2nd attempt I could not turn off so i plugged in usb cable held the power button in until window's prog could not detect device then quickly inserted paper clip to reset hole held it 3 sec then removed it .loader program detected.attempted upgrade. red fail a 5%.
3rd same steps as 2nd attempt. got to 17% red fail.
4th attempt same steps as 2nd attempt got to 100% it reset it self,black screen,jumped to reboot jumped to language selection and then wifi network selection for connection the jumped to home screen.you have to go to google-play.redoing you google account login.and reinstall any apps that you previously had installed.its very stressful
but if it fails just redo it .don't give up.
