The version 2.2 firmware is freeze my Mac before I install this last update (MBP81.0047.B1E). How can I install the last version (MBP81.0047.B0E) on terminal via ROM file: MBP81_0047_0EB_LOCKED.scap (extracted from .pkg of this http://support.apple.com/kb/DL1381) ? via bless utility? How?
MacBook Pro, Mac OS X (10.7.1)
But don't have any FirmwareRestorationCD download for 2.1 version..
then you can't downgrade until they update it.
Oh no! wait a lot months to make my MacBook Pro working fine again? Big Fail Apple.. =/
You do know you're entitled to warranty support, right? Call Apple and tell them what's going on.

For guys who upgrade the EFI of MBP8 to v.2.2 and after that gets a crazy problem. I created a solution http://goo.gl/CXbf1 #mac #firmware

Just take it to an Apple Store!
I did this.. They told me that it would take 25 days to fix. So I decided to create my own solution to the problem.
I solved in 5 minutes.
And now make available to friends of the forum here.

Apple has put us in a very bad situation.. 😟
Where was the 25 day Apple Store located?
How can I downgrade EFI firmware to 2.1 on MacBook Pro13" Early 2011?
