Hi, @all
the Chuwi Hi12 bios for Z8350 will erease windows key, so i will not publish it in the forum. If you want to risk, please send me PM.
In generally, we don't suggest that you flash the bios. It is risky and maybe brick your tablet if you use a incorrect bios or have a unsuccessful operation.
Thanks for your support!

Ofcourse you are right - if it is not needed - it is better not to flash.
But this is the warning fo ...

What advice are you needing ?

There are curently no bios upgrade for the z8350 Hi12 model

If you already have upgraded with the wrong bios, there is only one solution, wait for the right bios file and then flash it with a hardware flasher
I do NOT work for Chuwi. Please DO NOT pm or email me with problems you may have!

I read the post too fast and the warning was on the last page :/ I recommend also to add the Z8300 chipset info on each download link.

I never had problem to upgrade bios on devices before, so I ran into it.. and my 2 months old tablet is dead...
