Title: TL866II+ - cant read or write any efi bios -macbook pro or air
Post by: naitek on July 09, 2021, 09:52:05 pm

Hey Everyone;

i was so happy to get this programmer thinking all my issues would be resolved, but alas no luck;

--before starting;
all of these bios' are working in the pro/air and they are taken out of;
when trying to dump the file - i get all 0's or all ff's when dumping any of the bios chips
these chips are :
winbond 25q64fv  &
'macronix' mxic-mx25l64

maybe i just am unable to read these files or the Tl866II+ is unable to ?

any ideas?

thanks

nai
