After I reinstalled the older BIOS I get the eMMC missing error… So I guess there is no way to go backwards in BIOS. I can’t seem to get a break with this tablet… I had to reinstall BIOS 1.13 and my problems still continue. I left all night on the charger (after I saw the charging animation while it is turned off) and today when I tried to turn it on, the battery is empty. And now when I try to charge it, nothing happens… I tried to plug first to the tablet and then to power, first to power then to tablet etc…
If anyone has a dump of BIOS 1.62 that I could use to install, I might risk to brick the damn thing…
