    Bios Minisforum UM780 XTX

    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.

                      Lenovo Thinkbook 15 G2 ITL i5 (serial number: MP2BFZEF) bios request
                      by Wahaz
                      Hello,

                      I have a Lenovo Thinkbook 15 G2 ITL i5 Laptop (serial number: MP2BFZEF) that when I turn it on, the led on the power button lights up for 5 seconds, then goes out. There's no display and nothing happens.
                      So I thought it was a Bios problem.
                      I found 3 bios chips on the board, which I read with a bios programmer: two XMC model bios chips and a Winbond model bios chip. Each XMC model bios chip has two partitions named XM25QH128A [3.3V] and XT25F128A [3.3V]. And the Winbond model bios chip has three partitions named W25Q80BL 3.3V, W25Q80xV 3.3V and W25Q80DV 3.3V....

                      ASUS TP500LA BIOS request/repair/merge?
                      by jbonavita
                      Hi, my laptop wont boot at all
                      With original bios no POST, only LED lights
                      With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
                      Some issues
                      A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
                      B- If updated from 500LN version 203 to 300, the battery stops being recognized

                      Things I tried

                      1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...

                      [REQUEST] Dell G3 3579 BIOS Password & AMI Protected Range/BIOS Guard Unlock
                      by zenius
                      Hello, I have an old Dell G3 3579 (ST: 2WQ7LP2-8FC8) with a newer 8FC8 BIOS password. I have successfully attached to the flash chip (W25Q128JVSQ) on the motherboard with a CH341A programmer and made several modifications using Intel FIT (e.g., allow software SPI write) without bricking. I was also able to boot to a modified GRUB shell where I attempted to edit many BIOS security related options like BIOS Guard/Lock, Flash Signature Override, ME FW Image Re-Flash, etc.

                      Unfortunately, some of these modifications like to Intel BIOS Guard failed because it is fused into the PCH. Also,...

                      Changing BIOS Serial Number After Motherboard Replacement on EliteBook x360 G3
                      by Friend33
                      Hello,

                      I have an EliteBook x360 G3 where I had to replace the motherboard. Everything is working fine and there are no errors during boot. However, I have the issue that the serial number in the BIOS is incorrect. When I run the DMI tool under Windows, I get an error stating that I am not in Unlocked Mode and therefore cannot make any changes. I was able to change the Asset Tag directly in the BIOS. Now I am wondering, can I simply read the BIOS chip, change the serial number with a hex editor, and write it back, or what other options do I have? The old motherboard did not work at...

                      [HELP] G712LWS BIOS capsule
                      by TraJikar Mac
                      I need someone that can capsulate one of the bios files below, and i prefer the older bios version so i can flash it using CH341A tool into the bios chip.
                      The manufacturer BIOS files are bigger than the BIOSbackup1.bin files by 256KB and I don't know how to fix or recompile it.

                      You can see in this link a conversation between me and other people (Starting at page 10) who tried to help me (thanks to their efforts), but i still couldn't fix it and the laptop is considered as dead until now.

                      Also, I uploaded a backup file for the bios that I extracted by using CH341A...
