Bios out??? Mac did not start was created by gaets35
Hi everybody!
I tried to bypass an EFI Password but i didn't succeded in making any change (didn't get access to it).
so when i try to restart the mac.... Nothing....it didn't start.... only a very little green led flashing.
The mother board is down?
thanks for any help

no the MB isnt down
but if you attempted to the dump the firmware via hardware im sure something went wrong
if its not booting up anymore
what exactly did you do
and you are gonna have to find a way to read and write to the chip if not you will have a fancy paper weight

did you connect everything right?

worse case scenario you fried the chip just a matter of reflashing a new chip

so yesterday i was able to read and write the chip. But as i mentioned before, the mac didn't start. I try to start it with another battery and charger but nothing.
I think that the motherboard is dead.
Thanks for your help!

You have to zip it before you can attach it.
