A yeah it was from a Catalina beta, dated from the 11 august 2019 on my end, so it may not be the latest version, however it has APFS support at least. But it's from a working system.
You can at least flash it and try again the upgrade to Catalina, it's not supposed to fail every time.

If your issue is not related to EFI/BIOS then yes please open another thread (outside the BIOS section).

Hello friend, I didn't know what you did on the CRC32 (Cyclic Redundancy Check), could you help me with my original file I already changed the serial but the other one didn't could, Can the equipment work if we do not modify this parameter???

Thank you but I don't have the necessary dexterity to remove chips. As soon as I get the new caliper I'll try again to see if it recognizes the chip automatically.

Thank you for your trust but it's the first time I've done a job like this and pliers seemed like the simplest solution also because I wouldn't know how to remove chips. However, I discovered by taking a photo of the motherboard that the chip is the one in the photo I attach, therefore not a Windbond but by searching online it looks like a Micron. Does the bin file change in this case?

here is a video as a model.. this chip is removed, put in an adapter and then in the programmer.. you can find an adapter for this chip on the internet..

Thank you. I'll try as soon as possible because my ch341a programmer clamp no longer works and I've ordered another one.

don't use the clamp... remove the bios chip from the board before writing or reading, or stick wires between the chip and the programmer..

I apologize if I repeat the post but I'm not very expert in the forum rules
Good morning.
I need help. My old mac book air model A1466 EMC 2632 820-3437 serial C02M6TLEF5V7 is password locked on the firmware. I tried to make some attempts with the ch341a programmer but, not being an expert, I can't solve it. The programmer tells me that the chip is a 25 spi flash winbond w25q64fv. I didn't understand how to remove psw. I worked on the disassembled board. How do I know if it's ok?
Thanks for your help. I managed to save a copy of the bin file,but I'm not sure what I did.
In any case, would it be possible to have a new firmware with serial insertion?

try..
