Hello, i upgraded my Teclast X98 Air 3G from WIN8 ti WIN10 without problems. But now last working version is 1709. After upgrade to version 1803 or 1809 many drivers are missing and i cant manually install it because many devices are not visible in device manager. Drivers backup is not working….i cant return working drivers 1709 to newer version…( Windows upgrade assistant tell me : Device is prepare for upgrade )
Can somebody help me?
