Listen buddy. Your BIOS dump is damaged - this is for sure. As I understand it, you have already rewritten the EFI flash and, accordingly, you no longer have the original dump. I found a dump from the exact same macbook and changed the serial number in it. Try to record this dump and write here. If you do not succeed at all - no image, it means the matter is in your programmer or in the flash drive itself. You use HD Box as far as I can see. But despite the fact that your dump is damaged, your serial number is still readable. So I changed 1 digit in it. So it will look like the one on the back side of the MacBook.

I perfectly understood everything you wrote. But the fact is that your BIOS dump is different from all other dumps. Perhaps your programmer reads and writes the dump somehow in its own way. I did not work with hdbox but the dump is exactly different from what it should be. Look at the screenshots and make sure. (The first and third picture is your dump. The second picture is how the dump should look.)  Do you have any other programmer?

Perfectly. Yes, a dump without defects. I changed the serial number in the dump to 1 digit and checked for existence. Do not forget to write the dump with the same programmer that you read. If you need a specific serial number, write me a personal message with the serial number that you need.

i have wrote your given dump by the new programmer but result is black screen and only fan spinning. i have detected that dump size is 7.99 MB (8,388,607 bytes)  after you edited and as we know it must be 7.99 MB (8,388,608 bytes)

Well, why not. You must read the dump from your device. Even if the serial number field is empty. It is important. Or is the dump already overwritten and not native - not from this macbook?
