Hi people, how are you doing? I heard that it's possible to flash the MBP5.5 firmware about the MB61... why I am thinking about it? I lost my 2010 motherboard due to some issues and the newer 2009 motherboard has a firmware with the numbers 2009.0.0, but I saw others have MB61.00C8... not 209.0.0 and it shows USB 1.12 not USB 2.0; so I am trying to flash the MBP5.5 firmware since people said works nicely with bless -mount / -firmware <... scap> --recovery --verbose but it is only with black screen for hours, I only can regret the idea by rebooting it wrongly 4x, so it comes back again to the older one.. why it's not working?
