Hardware Error code 4ROM 2 40000008 downgrade Firmware
Hi iFixit community
I am in need of your help since I am looking to downgrade the Firmware of my MacBook Pro. Unfortunately the hold the power button down does not work, can you let me know how can this be done?
The version I'm installing is 2.7, from the looks of it, my PC has a newer one than the one mentioned.
Note: I have the needed version from apple.
