I tried your file and the situation is exactly the same as shiyab's file, in addition, when entering the bios to change the bios admin password, it still asks for the old password.

Hello everyone. Help me remove the password. I read about similar models and did not find a solution. I tried the same with 845. Nothing happens. It does not even enter the MPM. A full BIOS recovery occurs.

try this and feedback me

Good day. Thank you for answering. The password is still there. I tried to flash the BIOS separately. It does not give a result. Then I put everything back in place. and flashed both the BIOS and the EC at once. There is definitely a result. It gives me this message. When I try to cancel the recovery and reboot, it still asks and does not let me into the BIOS. After another reboot, it still asks for the password.

Hello everyone. I've tried a bunch of different options. Up to filling the FF with the entire EC flash, removing it. Replacing regions. Flashing other people's dumps without a password. And so on. But every time the laptop restores everything as if from the factory. I read that this platform has so-called protection against changing the BIOS. Does anyone know where it gets the information from? It's unlikely that the Multicontroller has enough memory to restore everything. And another question. There is a TPM SLB 9672 chip. What if I remove it and start the laptop? I understand that the processor uses it for encryption. Will it be able to work without it?
