Hello Friends! Trying to dump bios bin for Microsoft Surface 3 to recover UEFI password but running into error when running FPTW64 in CMD in Administrator mode:

fptw64.exe -bios -d dump.bin
Intel (R) Flash Programming Tool Version: 13.0.37.1556

Failed to Initialize driver for accessing PCI device.

FPT -i
FPT -bios -d bios_reg.bin

If it can’t be read then usually it cannot be written… get an IC SPI programmer.

EDIT:
Maybe the fastest one…
You may look in the forum for other Surface issues (Pass or corrupt bios recover) and draw your own conclusions from those user’s actions.
Good luck.

Thanks. So it sounds like I’m doing everything right? And the only way around this is to use a SPI?
