    If anyone happens to face the lines in TWRP (white blurry screen), reboot, when in TWRP goto Settings, Display and turn off screen timeout.

    Fixed it for me.

    Yes, Sorry, been busy…

    Charge your tablet.

    Unzip this file into your SD card, preserving the directory structure. I.e. you should have a bios directory in the root of your SD card that contains a number of files including “flash”. PLace the SD card into your tablet and boot this image file.
    In TWRP start a terminal command in “/sbin/bios” enter the command “./unk” (to set up ready for flashing the BIOS you provided, 806 and 207 are the BIOS versions available from Chuwi’s forum).
    If everything works you should see the message unzipped.
    Hook up your tablet to a charger then restart your tablet and let it flash.
    There is a potential issue in that secure boot will stop the flash tool from running, there might be a workaround if you hit this issue.
    Please note that you will see some errors when your tablet restarts, this is expected do not panic and cut power!

    Damn, the tools in the Hi8 TWRP are different to the the Vi10 TWRP…

    Here’s a package that should work, unzip click boot(.bat) and try the “./unk” command again.
    You’ll probably get an error about not finding startup.nsh and some paths will allready exist, this doesn’t matter.

    BTW I’ve found that I can boot the Hi8 TWRP recovery on my Vi10 Pro (without display) and use ADB to test stuff so I’ve actually been able to test the package this time. Whether flashing the BIOS will fix the USB issue is another matter…

    this one works…the bios version in the file is the same as in the device (flashing is done after some seconds – did it flash?)

    but you are right…the bios flashing doesnt fix the USB issue (if the flash was done and not skiped)

    I think it should take longer than that to flash, did you get the progress bar? The Insyde utility does skip areas on the Vi10, I think it only changes sectors that need changing and some are locked down against change.

    You could try the 806 and 207 BIOS, one of those would give a different BIOS version.

    Did Android start up again afterwards?

    Instead of “./unk” it’s “./207” or “./806”.
