Request: Beelink Gemini M BIOS dump (SN 4125HOLH70514 – Winbond 25Q128FW)

[Max74747]

Hello everyone,

I’m looking for a verified BIOS dump for a Beelink Gemini M mini-PC.
The device is now bricked after flashing the official BIOS file from Beelink’s website (M41N100_1018_GeminiM8G36.bin).

Details:

Model: Gemini M-H-8128QD0W64PRO

CPU: Intel Celeron J4125 (Gemini Lake Refresh)

Serial number: 4125HOLH70514

BIOS chip: Winbond 25Q128FW (8-pin SPI, 3.3 V)

Symptom: Power LED and fan run, but no HDMI output after flash.


If anyone has a working dump (.bin) for this revision, or can share a known good image, I’d really appreciate it.

Thanks in advance

Hope is right

Hi hoaca388,
Thanks a lot for sharing the M41N106.bin file — I really appreciate your help.

I’ve just flashed it successfully (erase → program → verify all OK), but unfortunately the system still shows the same symptoms:

power LED and fan turn on,

but no HDMI signal, no POST, no keyboard response.


It seems this BIOS might not match my exact board revision (AZW Gemini M Ver:4.1, Winbond W25Q128FWSQ).
If you or anyone else has a dump from the same revision, I’d be happy to test it.

Thanks again for your time and support!

Beelink support have three different bios versions for the Gemini M series https://dr.bee-link.cn/?dir=uploads%...ies%2FGEMINI-M ,did you try the other two ?

[Max74747]

Yes, I’ve just tried the other two BIOS files from the Beelink repository — unfortunately, none of them worked.
I’m currently in contact with Beelink support and waiting for their R&D team to provide the correct BIOS for my Gemini M Ver 4.1 (Winbond W25Q128FWSQ).
In the meantime, I’ve managed to find another working Gemini M unit with the same specs, and I’ll dump its BIOS to compare and possibly restore the bricked one.

Post the backup of the other working unit, it will need the TXE/ME firmware cleaning.

Here is the full dump from the working Gemini M unit (same Ver 4.1 board, Winbond 25Q128FWSQ).
