Friend could help me with this problem, I have no jellyfish yet, only ch341a.
I can extract this BIOS file even without the s/n ? if not, please send BIOS file with this serial C02N4E1PG085.

Model: 820-3437-a a1466 macbook air 13' 2013.

In the diagnosis by pressing the "D" when it switches on, it indicated this defect without serial number. That worked out, buddy, thanks!
