And the blue Teclast icon restore,etc screen doesn’t respond.
Connect usb keyboard over OTG cable or over usb hub and point recovery (windows update from sourse) button to start update.
Or go to the BIOS by pressing DEL on attached keyboard (you should attach keyboard and flash usb drives before TAB will power-on) and in the bott override option click the boot from UEFI flash device and automatic update will start.
Please note, you should prepare 2 usb flash drives in special formats (FAT32 & NTFS), copy windows image. It will able to update windows by this way. About usb drives prepare – you could find article in the tablets topic of this site – Teclast X98 articles about windows 10 multilang update.
Hope, this helps.
