Hello, I attached these files again.

Download my mod for Crystal Well, unpack and run:
fptw64 -a 0xE90048 -l 0xD8 -f fit_m.bin
fptw64 -a 0xF77D28 -l 0x5C18 -f ucode_m.bin

It works. Thanks for your help

Nice news!

Thanks DeathBringer for the instructions to disable BIOS write protection for HP Elitedesk 800 G1! It worked for me and the following command can finish without error:
fptw64 -a 0xF77D28 -l 0x5C18 -f ucode.bin

I'd like to downgrade the BIOS on my HP Elitedesk 800 G1 from V2.78 to version V2.71 (official BIN attached) as the new BIOS makes the computer slow. Can I do it via fptw64 and how? Looking forward to your advices.

I'm not a tutor.

Hi I also have the same model (HP Elitedesk 800 G1 USDT) and I am also trying to get a Crystal Well CPU to work. Will this mod work for my PC or do you need the specific fit.bin and ucode.bin of my PC?
