Re: A1708 820-00840-a efi lock
Hi,
A1708
EMC 3164
Main 820-00840-A
I had problem with running.
I have checked SPI and found out this problem:
Detected CSE Extension 0x03 with wrong Partition Hash at FTPR > FTPR.man!
Then I took ME Cleared DUMP here, replaced Serial number.
Everything is running but I get EFI password request.
So, EFI is blocked.
Would you like help me to cut the password request please!
Here is my original DUMP and good dump.
Thank you.

Re: A1708 820-00840-a efi lock
Hi,
Thank you.
But something goes wrong.
Doesn't want to run the screen.
Consumptions is jumping from 0.01 until 0.430A
In ME Analyzer i have got the same problem:
Detected CSE Extension 0x03 with wrong Partition Hash at FTPR > FTPR.man!
Below is my previous dump that I read after turning on.
It works but asks password.Last edited by AlexVG; 05-30-2023, 04:31 PM.

Re: A1708 820-00840-a efi lock
I can suggest what was before:
Somebody had tried remove the EFI lock before me. But had got the same results.
Probably he put wrong number, or would rather didn't change it.
Number in the SPI was C02TK51HHF1P
But on the bottom cover is FVFXQEK7HV29.
What do you thing may be different number cause of problem?Last edited by AlexVG; 05-30-2023, 05:10 PM.

3.2. Apple
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.
