Sorry title is wrong its a 820-00138-A ( 2015 15" retina)
Boots to question mark folder then grey padlock when I boot to ALT

From what I've gathered this is an EFI lock and I have looked at other peoples bin's before and after someone unlocked them and seem to be getting different results
Some change the 3 7F to 7C in the $SVS area and some just FF the entire area after the first $SVS until the second.

Are both ways acceptable? I'm still waiting for my soic8 to dip8 adaptors to arrive, so just want to get everything ready.
just to double check this uses the same ssd's as the 2013 & 2014 air and retinas right?

Both can work but I have had issues. If you have issue just upload the dump here.
Since when does a 3330 use a retina SSD? Just a normal 2.5"

Edit:
Oh title wrong....
I believe 2015 SSD has some different temp sensors so using a 2013 SSD in there wil give errors.
