Hi guys,

This original bios dump is not working, macbook turns on but no image.
Tried with a bios chip from same model and it works,but takes long to POST.

Same thing, board does not boot with this dump.

Can someone CLEAR ME region of this working dump?
This is the other 820-3435-A bios chip from another board

Works but takes 20 secs to boot.

Also if possible to keep the original SN:C02L31VJF5N7

Thank you!

Why the hell you are posting a dump that doesn't work and asking to clean ME region then?! You think it's a easy two minutes job to clean the ME region? And when the ME is fixed it will work in a magical way? I don't intend to play with it again just because you think so.

Sorry for that, but the first posted dump was the original that was not posting.
I dont know if it has been screwed it beforehand.

Since it did not worked, and to avoid loosing more time, I posted a second one that IS WORKING 100% for sure, only needs the ME region clean.

Sorry for the waste of time, but I had no way to check the first one.
But this second dump is working as stated before

3.2.2. 2012 to 2017
For 2012 to 2017 machines, BIOS must be edited and reflashed to clear the password. There are 2 methods for this:

Clear out the whole SVS store. There are other stuff in this store, no idea what they are for so better avoid doing this.
Invalidate the CBF2CC32 NVRAM variable in that SVS store which contains the encrypted password. You just have to change one bit in its name, so like replace the C with an A or whatever. Note that strings are UCS-2 encoded, so in the hex editor it'll show up as 0x43 0x00 0x42 0x00 0x46 0x00 etc.

If there is an iCloud pin, you need to perform 3x PRAM reset after removing password. If FindMyMac is still enabled, you have to reinstall macOS while being disconnected from the Internet, then reconnect after logging in and bind to a new Apple account.
