Thanks from my MBP

Just wanted to say thanks for all the nfo here. Managed to clear my EFI lock on a MBP mid 2012, using a TL866 programmer. I found with a chip attached to the board I just go an error message. So removed the chip and soldered it to the adapter. The schematic I was using for my board listed the chip wrong but was able to use the search feature on the MiniPro software to ID the chip correctly. After a successful Read/backup I used the Dump from this site, put in my serial and programmed the chip. Soldered it back on and the machine seems fine!

I guess some of the newer machines would be more of a challenge but for this model the process worked without a hitch.
