Hello I'm working on Dell E7440 (LA-9591P) with a blank Mec5075 and I want to disable boot block so I can program the entire chip. I read elsewhere that grounding FWP# pin will disable boot block protection, but programmer indicates that boot block is still protected. I am using SVOD1 programmer. Any help will be appreciated.

for what ? Is this like not to fix?
The laptop powers on but no S3 voltages, so I made a backup of the MEC 5075 and realised that it was blank and programmed it , but it is still not booting, so it is likely that the boot block has been affected so I want to program a full factory image into the chip.

I think you are going in the wrong direction
