Does it turn off - or just get black - sure you applied the correct string.?

Anyway you can boot up using -s and use the following:
Quote:
mount -uw /
vi /Library/Preferences/SystemConfiguration/com.apple.Boot.plist
go to the lines <key>device-properities</key> and press dd then go to the <string> line with the Hex string and press dd again - save the the file using :wq + enter and reboot - this will remove the EFI String again.
