Your Chuwi is dead.

What is your model? Chuwi HI12 Z8300 or Z8350?

I think that you flashed a bad BIOS.

For this reason you must flash your Chuwi by hardware. I made last weekend, it’s not difficult, but you must shop a programmer, adapter to 1.8V, Torx nº4 and clip chip.

Hi all.

After a bad flashing of the BIOS my chuwi hi12 was dead, but it was able to revive it through a hardware flashey. My problem, now, is to get the image of windows 10, but I can not download it from the link of the first post (forum.chuwi.com) “Chuwi Hi12 Dualboot Windows(TP) for Z8350CPU” from mediafire, as the download is cut continuously, every time i lose conecction….

Someone can put a mirror. Thank you very much.
