Good evening, would anyone have the macbook pro bios dump file a1398, model of the emc2910 820-4652A card? I went to try to read the bios chip and ended up burning it and it doesn't work anymore. The initial problem was firmware password, but I ended up damaging the chip. I got another chip just like that, but it was on a different model board. Would there be a way to re-record the bios on this new chip? I have the bios recorder and the adapter. Once you've done that, would you have how to write the card serial again? I thank you all right now
