<SOLVED>Kernel panic after changing to wrong system def

[mcoufi]

Hi Guys, looks like I messed up bad. I had stable 10.7.3 mac mini. Just put gtx 570HD into it. It was running fine but really slow So after reading about installing drivers, cuda, kext I changed my model to iMac 12.2 through multibeast, still graphic was running slow. I don't know what was I thinking but I run chameleon wizard and changed to mac pro 5.1 in order to install nvidia drivers, also through kext utility I installed kext for my gpu. restarted and panic!!! I don't know which one caused it but:

Is there any way to change model name ?

This worked
- boot in single user mode (parameter "-s")
- "mount -uw /" (enable write on root)
- "sudo nano /Extra/smbios.plist"
- find string 5,1 and replace by 3,1
- "ctrl-x" to save and exit
- "reboot"

Just tried 5,1 (not sure why) and ran into kernel panic. Thanks for the directions (above). Went in and changed def back to iMac 12,1. Back to a happy Mac
