How to do a clean reinstall of Windows 8.1 on X98 Air 3G?

[Bjorn Muller]

I need to do a clean reinstall of the original win 8.1 (with Bing, if I remember correctly) to my dual boot X98 Air 3G. According to a Microsoft support guy, there are only 2 ways to do it if I want to be able to activate with the stored Windows key. Either I need the Teclast original ISO or I can use the Microsoft tool to download a USB installation media in Chinese FROM WITHIN CHINA!

Has anyone succeeded to do this?

 

The background for any interested X98 Air 3G owner: A major update of Win 8.1 failed some time ago, and after that, Windows Update was unable to find or download any more updates. I eventually found out that Windows Update has an inbuilt repair utility,and it solved the issue by deleting all repair history and update then succeded. But when it was done, I had no touch control. It turned out to be not just Goodix Touch control missing, but a massive breakdown of Windows, with lots of devices “not connected to Windows” anymore. I could see them in the Device Manager only by enabling “View hidden devices”. I tried to do a Windows recovery, but it got stuck at 8 %. After reboot, I only get to Windows Repair (in Chinese, but fortunately with symbols to guide). All options there fail, except installing from external media remaining.

9. install 9gsensor the exe file first
10. then reg file
11. then update drivers in device manager for all that not work by choosing Windows 10 Drivers X98 Air 3G folder
12. restore the key.bin fileÂ

•   Install thebackup tool in C:\bios\
