Hello everyone,


i have installed a wrong version firmware (efi/smc) upgrade on my Macbook 5.1 (late 2008 unibody) 13.


Unfortunately, this pkg is for MBA 13, but the installion didn't stoped by system, after reboot by a gray screen, the fan run in high speed and the system (screen and hard drive) go to sleep himself, it can be weak up by press any key, but it will return to sleep in 2 seconds.

During about 4 months, i have already tried all of these below:

i tried also almost efi and smc version firmware upgrade, and sudo bless, sudo perl ./  ...etc


so now my Macbook:

Boot ROM version: MB51.007D.B03

SMC version: 1.66f57


please tell me that it dead or i can bring it back myself by some other way (apple store could change the main bord but cost too much)

thanks a lot !

MacBook, Mac OS X (10.7)
