Apple Macbook A1989 820-00850-A Bios Password

[Dan20701]

Hello all, I have been trying to remove the password on a Apple Macbook
A1989 820-00850-A with no luck, I still have a lot to learn yet.

I got this file from ******************** pay site and its locked, it boots but
still has a password on the system.

Could someone remove the password please, The chip I have been replacing
is U2890 USON8 2X3mm the bios file is 4.00mb, I have another file but its
only 1.00mb, Have I been programming the right file the 4.00mb W25Q80DV?

The original chip got destroyed.

Thank you very much for any help.

3.2.3. 2018 to 2020 (T2)
For 2018 to 2020 machines with T2, T2 DFU restore with Apple Configurator 2 can clear the EFI password, however it will not remove the iCloud account. iCloud account is bound to the T2 of the machine on Apple servers and cannot be permanently unbound except by Apple. Methods to bypass activation screen thanks to checkm8 exploit exist.
