so weird... your bios (d4d6) ID and guid and mine are the same.. i have d2d3.

until my OTG hub arrives, then I can enter BIOS screen to verify.  As of now, that BIOS is extracted via AFUWIN.EXE through windows 10.  BTW, My tablet was ordered and arrived in November of this year and it's barely 1 month old.

as what system info showed then your bios is really d4d6.. im really wondering how they manage to pull out bios.bin. it seemed afuwin.exe cannot read the bios emily gave. and to think of its size, bios.bin and the bios that afuwin.exe create is different. that means chuwi or whoever pulled out the bios used an unknown program aside from ami tool.
i looked at the bios emily gave, and this fpt.efi is a flasher, which they renamed it so no one will know what this tool is..luckily i found this out but unfortunately yesterday i had a fresh install of windows on my laptop and all the data i collected about the tool they used has gone. data recovery is impossible coz i always do overwrite erase before i install windows. i forgot i didnt transfer it to another drive..so now im figuring out again, so i can find the right tool for backup on chuwi bios.. i really thought this ami afu for aptio v is the right tool..damn!..

I am pondering the same as how AFUWIN managed to pull the BIOS ROM and save it.  All I can see is the BIOS file posted in the forum for Vi8+ versus the D4D6 I extracted by AFUWIN is pretty close in size.  D4D6 seems to be a bit larger in size approximately 6MB in size.  We will never be able to confirm the D4D6 bios extract from AFUWIN on the tablet until Chuwi actually releasing the official D4D6 in the forum.  By then we can compare the saved BIOS vs official BIOS.

Question that I am really trying to figure out is "Why chuwi not releasing D4D6 bios in the forum when their product actually shipped with such BIOS on the tablet.
What are they up to?

Hm....I just did a quick compare between the BIOS backup I extracted using AFUWIN on my Vi8+ and the bios.bin from the link above (google drive) and here are the differences.

Extracted ROM using afuwin = 6144KB
bios.bin = 8192KB (date July 6, 2016)

That's quite a bit difference in size.
Quick comparison using UltraCompare also show significant differences too.

Does this mean the extracted ROM using afuwin.exe is not reliable?
