Hi, I'm Russ and collect retro laptops and have a large collection of 100+ from 1991 to 2007, I love tinkering with all things electronic, and run a small homelab ...

So long story short, I was trying to modify the serial number because of an MDM issue on this machine (purchased 5 years ago, MDM was linked to BYOD form a now deprecated platform)
I have dumped the original ROM using the cable and a CH314 programmer, this pulled the dump fine, however when it came time to reprogram, the cable needed to be placed in the other direction to write back. Now I constantly get a fail on the verify of the EFI flash, has anyone else had this happen.

I have unlocked a large quantity of machines in the past for a friend without issue, this is the first...
