Changed my SMBIOS to iMac 14,2, now I can't boot

[maximusprimus]

I should actually say I did two things that which have caused this issue. In preparation for the Sierra update (I still haven't installed it yet, I'm on El Capitan), I changed my system definition to iMac 14,2 and also updated Clover. When I updated Clover, I also moved FakeSMC.kext into the /EFI/CLOVER/kexts/Other folder on my EFI partition of the boot drive. Now, when I boot, after the Apple logo I get a black screen followed by a reboot. If I boot in safe mode, I'll get as far as the blurred background image shown on the login screen, then a black screen and reboot. I backed up my boot drive before making this change, but I cannot boot into the backup either.

My specs in my profile are accurate.

These are the things I have tried:

• Booting in safe/verbose mode
• Booting from a backup partition in safe/verbose mode
• Ignoring kernel cache
• Changing my system definition manually in Clover to MacPro3,1 (which it was originally)
• Changing my system definition and board definition to MacPro 3,1
• Booting from a vanilla Clover install on a USB stick and trying all of the above
• Booting the OSX Recovery partition (gets stuck on a grey screen)

Does anyone have any ideas as to what I can do to rectify this situation? I thought I had my bases covered when I backed up but I guess not. I've attached some screenshots of what verbose mode is displaying at the end.

Thanks!

UPDATE:
I changed my graphics injector to Duckweed (and disabled the ATI injector) in Clover, and now I'm able to boot, and login with no problems.

Hi,

I have the exact same issue; tried sierra update from yosemite steps & changing my profile from mac pro6,1 to imac14,2 caused me black screen.

Can you teach me how you did following when you cannot boot into mac os x?

• Changing my system definition manually in Clover to MacPro3,1 (which it was originally)
• Changing my system definition and board definition to MacPro 3,1
