Hi i upgraded Intel ME FW but then on downgrade got cought by VCN.
I did this thing [Guide] Unlock Intel Flash Descriptor Read/Write Access Permissions for SPI Servicing
It has succesfully created spi.bin dump means my FD is unlocked?
Then i went back to guide and tried to flash my ME with Intel Flash Programming Tool and got the error “Error 167: Protected Range Registers are currently set by BIOS, preventing flash access.”
What i do wrong?
my bios if neededbios
It depends on what actions were taken from the guide and made before to the system.
You took actions to gain access, granting you the possibility of reading only, if not edited and flashed/programmed as so, after reboot the system is back to original state (FD locked again).
You do not provide detailed info on the actions taken and what method used, so we can’t guess what’s wrong with your attempts.
I suggest reading back the guide with a bit more attention.
No changes were made before, i just updated firmware than wanted to go back.
1.First what i did is checked my locked/unlocked FD by the guide.
2.After tried to flash Intel Me with FPT got 167 error
3.Went to this guide did what it says and still this error, although even in this guide i had only “variable” locks in my bios they are not locked to me as i understand, but i disabled them anyway via “grub” from flashdrive.
For now i don’t understand what to do, maybe modify bios and flash it but i don’t know what to change and where.
