Macbook A1706 EFI removal

[keats11]

I have a macbook A7106 model with an EFI lock on it. I am resonably good at micro soldering, so I removed the BIOS chip and removed the "password section" which is the block of code following the "$SVS" token. There are two such instances in the BIOS. More specifically between addresses
:a) 15B050 -> 15B850 b) 15D050 -> 168FF0. After putting the updated BIOS back, I get a folder with "?". Tried doing MacOS recovery when it says "Recovery Server Could not be Contacted". I did this like 25 times so I know it doesn't work. I have Wifi and also have a wired ethernet adapter. It doesnt work with either. Does anyone know the complete process for removing the EFI lock? I am worried all the connectors will break before I try out a hundred different things.

Re: Macbook A1706 EFI removal

I tried flashing this just now. Same result. It comes with the recovery screen, when I say install macOs Sierra, it thinks for a minute and says "recovery server could not be contacted". Wish there was way to debug this rather than guess. I also had a USB boot that my wife says she had created onetime. Not sure if that would work.

So efi password is gone, now you have trouble with installing new OS.
If new install doesnt work with wifi then try with a usb stick

Hello good friends of this wonderful community, I have an A1706, and I want to remove the EFI password, since when I try to reinstall the system, the little padlock appears. I intend to do what our friend did in the first post about the $SVS token. However, I see that in the different instances of the BIOS backup I make, it always changes and is not identical as in other cases. Even if I change it, it will continue to work the same. That's my question. ?
Best regards to everyone.
