I was able to solve it. It turns out you have to simultaneously press vol up, vol down and power ( all 3 buttons )

Hello

I also had same problem with my Teclas x80. I followed the russian guide and it solved the issue of SD card which suddenly went a-wall

As no everyone speaks russian ( neither do I …did some google translate)

Here is what you have to do.

1. Open Windows Setting
2. Open “Updates and Security”
3. choose recovery
4. choose advanced restart
5. On Next screen , go for Solve Problems ( Icon with wrench and screwdriver )
6. Advanced, Startup settings
7. At this point make sure you have your USB OTG plugged in with keyboard, and Restart tablet with pressing the “Restart now”
8. Tablet will reboot and On first screen you see different options to boot,  choose 7 or F7 to run Windows in mode which will allow to install unsigned drivers
9. After reboot , go to Driver Manager and look for  Intel SD controller, not SD Storage Class controller which is with exclamation mark
10. So in most cases updating one should do the trick but it can happen you need to update all 3. So tap and hold on one and Choose “Update Driver”
11. Choose browse my computer
12. This is important part…instead just choosing the driver ( which won’t do anything as windows will claim latest driver is installed ) You have to choose ” Pick other driver from list”
13. On next screen choose “Have disk” and there you can pick your driver (downloaded and extracted from attachment)
14. Windows will say that driver is not signed, with red cirle etc. ..just ignore it and install .
15. If needed repeat procedure for other 2 .
16. Restart and enjoy your SD card.
17. In case SD card will disappear again , you can repeat steps 8-13 to have it back. You don’t have to launch Windows in Special startup mode as driver is already there . You just have to ensure that the correct one is installed to SD card controller

Hope it helps 🙂
