Re: Asus strix b660-i itx, bios unlock, FPT Error 167: Protected Range Registers
Thank you for your help!
I have done that! Descriptor is already unlocked!
I get this error with descriptor (and all other regions) unlocked!
I am not home right now. I can provide more photos if needed.
When I go home, I will make a full dump (not just bios region) with FPT, and I will open it with uefitool so you can see that all regions are unlocked....Last edited by greg.chalk; 10-06-2022, 04:48 AM.Leave a comment:

Re: Asus strix b660-i itx, bios unlock, FPT Error 167: Protected Range Registers
partial success! (I am almost there!)
After much appreciated SMDFleas observation, the correct bios chip is GigaDevice 25B128ESIG (motherboard layout in manual is wrorg!
)
So I used the ch341a programmer, I made a whole bios dump, I modded it, and I flashed back to motherboard. Succes! All regions in bios are unlocked!

Thank you for your response
I tried, but I think this works if bios get corrupted. You cannot force it (except if you corrupt bios on purpose
, not a good idea I think).
This guide (and others in that forum) is my bible. I tried it but the pins are so small that is almost impossible shorting the pins.

I think I have to change some vars so I can flash with FPT, but I don't know which one to change. I have already disabled bios lock but that's not enough obviously.
Maybe there are locks in other places other than setup?
Maybe @SMDFlea can help.

Re: Asus strix b660-i itx, bios unlock, FPT Error 167: Protected Range Registers
Thank you for your fast response.
I am not at the pc right now, I will flash it when I will go home.
I don't have access to the whole bios (it's locked from Fd descriptor).
I only have access to the bios region ( and even then, bios has separate locks).
Also my motherboard [B]doesn't have bios flashback[/B], so I can only flash through [B]FPT program[/B].Re: Asus strix b660-i itx, bios unlock, FPT Error 167: Protected Range Registers

Asus strix b660-i itx, bios unlock, FPT Error 167: Protected Range Registers
Hello,
I updated my pc, from Evga z270 itx to Asus b660-i itx motherboard. In my old z270 motherboard everything whas easy because everything in bios was unlocked (fd, me etc), and could do everything I want.
Now in my Asus b660 everything is locked (except main bios region). I dont mind so much but I want to unlock bios so I can flash a new splash screen (I have done it with my old motherboard).
I made a bios dump with FPT ([B]fptw64 -d mod.rom[/B] -bios), I modded it and I tried to flash back
([B]fptw64 -f mod.rom -bios[/B]). I got [B][I]Error 167: Protected Range...Last edited by greg.chalk; 10-02-2022, 10:57 PM. -
