I agrre with these considerations as when I was experimenting Recovery Mode on Acer series I found that many Eeprom were Write Unprotect when laptops had original (from manufacturers) Bioses and after update Eeprom begun Protected.
Same thing for .efi module modify ! all mods will work after flashing not before !
When InsydeFlash write Bios and in UEFI is worse, The actual Bios check the new bypassing InsydeFlash control !
I exprimented many things with Descriptors and ME Region so I agree completely with Xsmile !
I think that Donovan is much forward us as He has done many experiments and disassembled many modules (He knows better CodeRush and his discoveries), but
He don't want to share yet it.
I know that so far the better way to unlock all was mod original, do the Recovery and get full control on Eeprom (excluded Descriptors Region only way is SPIPGM),
but I am experimenting now for Acer that in new series V5 Recovery is not present and all Eeprom are write protect like the Insyde know where was the hole and They have patched !
So It's very difficult as We have to Patch InsydeFlash with dll and then the Bios to flash, but We have to get a SPI Programmer too !
