Here is a backup of the bios I had (I made the backup with the aptio v efi bios tool) https://mega.nz/#!49FiFQII!Jv-FjkCdVSO9pcZqvOCQ3SqMqAoGSULIWTutLKx4AIg . It the one dated 12/31. It works fine. You will have to flash it through the efi shell. Here is intel’s 32 bit efi bios update tool fpt.efi https://mega.nz/#!JoURWSZJ!S3-PsC7PljwIsb-v9jxSV6kkLqrOkG7IFPwqfMcMYWw . Or you can use amibios’ aptio V version of the efi flashing tool available here: https://ami.com/download-license-agreement/?DownloadFile=AMIBIOS_and_Aptio_AMI_Firmware_Update_Utility.zip I don’t recommend the dos or windows aptio v bios flashing tools, they’re prone to crash. I also don’t recommend the alpha bios released by chuwi, as its 64 bit (and the 12/31 version is 32 bit) and its very likely your tablet will become a paperweight after an attempt at flashing it. Put the files (unzipped, of course) on a flash drive (in the root of the flash drive, preferably), plug in your usb c otg or micro otg with usb c adapter (in my case) and enter the bios by hitting “del” at bootup. I turn quiet boot off, in the boot options and set the boot up to 3 second delay, for future use. Then go to the very right menu and select load efi shell from a usb drive (or something like that), it will load the efi shell, hit “esc” after a few seconds (when it says to hit “esc”), or it will reboot. Mount the usb drive by typing “fs3:”. Then type “fpt.efi -f backup.rom” (to flash via the intel method, provided the files are on the root of the usb, if not, just type ls and it will give you a directory list) or “afuefi.efi backup.rom” (to flash with amibios’ tool). After it completes (with both amibios and intel methods) it should reset, but if not, type “reset”, it will go into the bios and do the actual flashing at that point. I would recommend you backup your current bios with the amibios tool, by typing “afuefi.efi /O”, that’s an oh, not a zero, as I don’t want to be responsible if things do go well. It will backup the current rom to the root of the usb, or whatever folder you are currently in. In fact, I am not responsible, and this is done at your own risk and I would also highly recommend the battery be completely charged. I would also recommend the intel method of flashing the bios through the efi shell, as that is what the folks at chuwi do. Please backup the current bios and charge the battery first though. Hope this helps somebody. Also, if your tablet is already borked, you can try, just putting the backup of the bios on a thumb drive, in the root of the drive and name it amiboot.rom . might work, might not, sometimes the naming of the rom differs, you will have to run Andy P’s SLIC tool from My Digital Life to be certain the name is correct. Most bios manufacturers have a secure boot portion of the bios that is protected and in instances of “total annihilation” of your bios, you can still recover because this secure boot portion of the bios will be “looking” for the rom on the primary usb port upon powering on.

 

Hello Robert, thanks for this information I will try, I have the bios 109 and your one seem to be more recent. Is it better and will solve the battery/screen issue ? Do you know if it’s for a specific model of HI8PRO ? Thanks.
