Hi all,
i wanted to change my running system with Ryzen first gen CPU into a gen 3 this cristmas.

The Bios before the upgrade was only fit to run with the gen1 (Summit ridge) so to get it to run a biosflash was needet.


I flashed via EFI Shell but did not do a backup of the running Bios beforehand.
BIG mistake

before flashing i did the compability check and i got no errors.
example:
fs0:\EFI\BOOT> AfuEfix64.efi existingbios.rom /d


the flashing i did with this command.
fs0:\EFI\BOOT> AfuEfix64.efi existingbios.rom /P /B /N /K /X /L

the flash failed on "Erasing/Uptating NBC Block around 40-50%

I tried multiple times to get it to flash properly but it always faild at the same point.

After N.tries i gave up and powercycled.
Now i have Fanspin, no postcode, ofc no post and power button + reset do not interrupt
It´s a BRICK

-------------------------

I did research on how to fix this,

so i bought a CH341A programmer(black pcb) with adapter and Probe-Clip

Software i use with the CH341A atm is: NeoProgrammer V2.2.0.10


Board EEPROM:
Winbond 25Q128FWSQ
Supplyvoltage is 1.8V (datasheet of series says so)

Desoldered the Chip, because CH341A couldnt find/read Data from it.
I guess the lenght of the Datalane-traces on the Board is producing to much wave impedance to use the signals.

;Desoldering worked and the Bios images i saved for comparrison with HxD all match.

I tried/still try to unterstand how to translate the Bricked-Bios.bin with UEFITool NE 59a so i could backup Mac adress, UUID, SN... to put it into a Bios from asrocks supportpage but the HEX values i see in there, are gibberish to me.


Can someone pls help me i´m stuck here
