Management engine presence failed

It's a very odd one, I can't boot into OSX either via the recovery or a fresh install, it gets as far as the Apple logo/ loading bar then freezes.

I managed to install Ubuntu (on the HD) and it runs an absolute dream. This lead me to try ASD where I get Management Engine Presence test - Error not found

From a bit of digging I found some one else who said the reloaded the EFI through terminal. I have no idea how I can get to a terminal that would allow me to do that however. Maybe single or verbose user and run it form there?

Any help would be massively appreciated.

Have you cleared the PRAM and SMC? Which OS X are you running? Have you tried updating the ME region of the bin file? Is the EMC the original or did you download it?

I would like to know where you read that at???

Also I have a mac with a similar issue and whenever i get a chance I will look into it.

I would recommend that you use an external drive with OS X installed to see if the Mac can boot via the external drive. If so, then you can just use the Terminal located on your external. Also if you have any Recovery Disk or an OS X Install media (cdrom, usb, etc.) then there is always an option to use the Terminal located at the top under Utilities. Other options include using Target Disk Mode on your afflicted Mac to see if you can boot it from another instance of OS X (either another Mac or Virtualbox). If you have a moment head over to the Blog section here at Ghostlyhaks and take a look at the article on setting a clean ME region, I believe there may be some useful info pertaining to your situation! ghostlyhaks.com/blog/apple-efi/25-clean-me-region

(I would also like to know where you read about the person being able to reset EFI through Terminal!)
