The system is clean installed succesfull. After reboot the system is asking for a login password, but because of the screen driver the screen is reversed. I tried to load the driver, but none of the interfaces are working. The OTG port is not working. The USB Hub attached to the OTG port is not working. The external USB port is not working. The SDCARD is recognized, but only when I tried to reset the password. Then is system is checking the SDCARD and tells me that the Password file is not valid on the SDCARD.
Please advise how to fix this tablet.
Cannot add a keyboard so I did not get into the BIOS yet.
