does not work anymore…

First: Download X80H fastboot firmware from repository here or from Teclast’s English website (Google),  Always have these handy.

Leave it charging powered off for a full day. (Sometimes battery.manager fails on these rom. It can  even take over 13 hours to charge back to 50%)

Hold Power + Volume Down for 15 seconds. (Hard Reset)

Power On. (If the device boots, wait until home screen. Even if your usb prompt warning is gone flash the official firmware you downloaded. There are tutorials here and in the archive itself.)

Go to settings > developer (if not there go to about>tap build version untils you activate developer options). Turn on Dev options and USB debugging. Proceed to flash rom.

It’s normal but not frequent behavior on these Chinese OEM roms. Blame Intel for the kernels they provide. You don’t have to worry too much about flashing, after charging to 100% it will re-calibrate. If it happens again just do the same thing.
