Re: BBS MOD MxP APPLE BLACK BOARD SERIALIZER

Hi,

Too many variables here, so not sure if this sw has fried the efi rom or maybe a wrong sequence missed by me (thinking maybe I should have done a PRAM reset at first reboot).

Just soldered a new rom correctly programmed and with sn written on it from ebay (my first solder so won't embarrass myself by posting pictures here ).

And it's alive. just needs an os re-install.

But long story short it all started with me not blocking that "apple security update"...

Re: BBS MOD MxP APPLE BLACK BOARD SERIALIZER

Is this compatible with 820-3787-A boards?

Hi,

First off, I'm not a specialist, at best an amateur, and just hoping for some sanity check with you guys.

A quick summary after 5 days of checking power rails and forums and board schematics (*I don't give up and can't afford a new mac):
- found that macos security update has flashed wrong fw on the rom just before I installed a fresh ifixit battery
- the fw installed was for macos 7.1 - 2006 ( have this in installation logs and pictures...
