help with T8 BIOS (I have checked all the posts and my problem is unique)

[mini_fans]

I have two Wintel Pro W8/T8 but they are slightly different. The first one (I call it Model A) has 2xUSB 3.0 with WIFI 5Gh support, while the other (I call it Model B) only has 1xUSB 3.0, 1xUSB 2.0 and no 5Gh WIFI.

I have teared both down and found their motherboards are different too.
Model A:
T8U_V1.1
2018.12.07

Model B:
T8_V1.5
2017.xx.xx (I forgot to take picture)

I broken the Model A's BIOS when I tried to implement a BIOS update using the newest BIOS shared on this forum ("T8U007_ACEPC_LOG_20190831.7z"). I then tried the "T8_V1.5_LPDDR3_S1N12B4A0_X64_20170817.bin" and failed two.

I believe the above two BIOS are for my Model B because its motherboard is tagged with 2017.xx.xx.

Could you please provide me the BIOS for my Model A? i.e the model that supports 2xUSB 3.0 and WIFI 5Ghz?

Thanks for your help!!!

Hello, please turn on and press the DEL key to enter the BIOS, and take pictures of us under the BIOS interface. We need to observe whether your WIFI module is universal.

Hi, thanks for your reply. The BIOS has been broken and therefore can't POST. The WIFI module is AP6255 and I do have took a picture of the motherboard with AP6255 on it.

I have some experience with CH340 programmer by the way. And I know the SPI ROM chip, Winbond 25Q64FWSIG, is 1.8v which need voltage transformation. I have the tool.

Hi. The BIOS you provided is "T8U007_8821cu_acepc_log_0428". But my WIFI module is AP6255 not 8821CU. Can you re-send me the BIOS for AP6255?
