[Request] ASUS PRIME Z690-P D4 BIOS unlock

[badger2k]

Hi,

this request is linked to another thread i created

I need help trying to insert my UUID, Serial Number and mac into a stock ASUS BIOS file

Well, i tryed multiple hours yesterday to find anything like setup_var, bios lock etc. using different versions of uefi tool and ifr extractor, without any success. I just cant figure it out. Another concern is that the bios is split across two Chips. What would that possibly mean for flashing with a programmer? [Screenshot 2023-05-16 104926] [2023-05-16-11-08-08-001]

I am currently on the latest BIOS 2404 and i want to roll back to 1xxx BIOS versions. I already successfully unlocked the flash descriptor, dumped a backup and extracted and iserted the UUID into a stock bios file.

Can someone help me to remove bios locks? Because i get “error 167: protected range registers” when i try to flash a File via FTK/FPT. I already tryed to find the corresponding setup_vars myself, but with no success so far.

Here a link to the Support Page for my Board
https://www.asus.com/de/motherboards-components/motherboards/prime/prime-z690-p-d4/helpdesk_bios/?model2Name=PRIME-Z690-P-D4

I am able to roll back to 2014

Thanks,
Badger

I gather, you have modded the BIOS but are having issues getting the modded BIOS flashed onto the board, is this correct?

Have you tried SCEWIN to disable the BIOS lock (BLE BIOS Lock Enable) bit/setting? See my guide under point 9.

Alternatively, have you tried using ASUS CrashFree BIOS 3? See page 56 of the board’s user manual. It involves putting the BIOS as “ASUS.CAP” or PZ690P.CAP" onto a flash drive.
