sorry but i didn't understand ... I said i erased bis chip by mistake

So now you don`t have a backup, thats why you must use another bios.As i said,you must edit the serial number thats already in the bios and add yours.After that the fsys checksum has to be changed.

@iori1881

Firstly, this is a telling off, stop erasing chips 'by accident', this is the second time. Please learn to do it properly, take the time to learn what you're doing wrong. There is some excellent information here by piernov:

Second, the firmware you last uploaded is corrupted.

Your new bios is attached; I used the file from post#14 and inserted your serial into the Fsys Store and cleared the NVRAM, please try it and write back.

In that case, I've built a factory image from the repo, placed a donor Fsys store in the NVRAM at 0x20000h, and inserted your serial number. I have personally tested this firmware and it works. Please try it and write back. You must write it with your programmer, and then verify that data was written correctly.

The previous file was not unlocked properly, and the EFI lock is still present anyway.

Try this and write back.

Hello, I need an unlocked bios for MacBook Pro A1708, EMC 3164, Serial number: C02VQNXAHV22, unfortunately the current memory is damaged and it is not possible to read the old firmware, the previous memory had an EFI lock.

Thank you in advance
