Hello everyone,

I'm trying to fix a macbook pro intel i5 2011 emc2555 S/N: C17M6Z4DV13 which doesnt start i check everything and conclude that maybe efi bios was bad, i downloaded a dump from EFI REPOSITORY and now the macbook starts as soon i connect the charger (now it charges btw).

If just use the battery i can start it normally (no video or sound) i clear nvr ram and i dont think it restarts as it should.

I attach in a zip both BINs, my original dump and the one i downloaded here.

thanks and best regards

hello again, I tried without a hard drive and was free of password, I ignored that when changing hard disk is protected with password pin, should I re-program?

@Brunet. Take your dumped BIOS ROM and open it in HxD. Search for "override-version", type "text-string". the serial number is just after this.:-)
