Bios Minisforum UM780 XTX

[garretofriviaaaaa]

Hello, Basically a customer tried updating his mini PC using a USB stick but it bricked the computer. I've tried flashing a new chip with a CH318A programmer using neoprogrammer and a ROM file from minisforum's website. From what I have read on the forum here, there isn't a readily available guide on how to serialize an existing bios to the motherboard. I have a dump from the original BIOS chip, I did an additional one and did the fc /b command to make sure no discrepancies were found. The machine model number is Minisforum UM780 XTX, machine serial is MC495UU78XQQMQA0089, Board Serial is F78SD784048A1050804. I have also attatched pictures of the serial number and the board serial. Please let me know if I can provide any additional pictures or information. Thank you.

I just had my UM780 XTX brick itself while updating to the 1.06 bios from 1.05 version via Win 11 24H2 (Preview). It got about 31% through flashing and BSOD with the infamous "0xc000021a" error code. To be fair I was having problems with this unit running windows 11 23H2 prior and I should of probably updated it via the uefi shell. But now I have a fairly expensive paperweight, so if anyone knows of a way to flash a recovery bios to this then let me know. I've recovered older mobos before, so I don't mind fully disassembling it to do so, as I have no idea where or what kind the bios chip even is on this mobo.

Edit: Well after looking online a bit longer, it seems this bios chip will be too far out of my league to repair as I lack the tools and equipment to repair it properly. If anyone in the DFW,TX area knows how or a place I can get it repaired then let me know as I don't mind paying for it as it's my main system atm but I have plenty of spare PCs to use in the meantime, this was just the most convenient. If not I'll just replace it whenever a similar unit that has a similar Ryzen based cpu, dual nvme slots, bult-in 10GBE networking and Oculink comes out or replace it with a handheld unit with occulink when I can afford that.
