Hallo,
sure i bricked my x80 pro after changing some values in the bios. I hadn’t thought about that there is no reset button.
So after saving the tablet doesn’t start anymore. After some search i found the thread that somebody has some similar Problems with an x98pro and solved them by flashing an unmodified verison of the bios directly to the SPI Flashrom of the tablet. And this was what i did, i bought some CH341A Programmer soldered the 8 Connections to the spi chip and flashed the bios file from above (Thx again machetekills). And now its alive again.
this was my experiance, i would say doing this is definitly nothing for beginners.
I hope this was helpful.
