Hey guys, in order to flash the firmware of my Santa Rosa MacBook Pro's optical drive with one of Ben11's well-known firmwares, I had to modify SystemVersion.plist located in /System/Libary/CoreServices. This was due to the lack of 10.5 support of the updater-app. So I logged in as root via Terminal, replaced 10.5.7 with 10.4.9 in SystemVersion.plist via nano and the application updated the firmware fine. However, I forgot to revert the file before a necessery reboot. As a result of the reboot, I lost the superuser / root rights and am now unable to revert SystemVersion.plist. As it is still configured as 10.4.9, neither Terminal nor most other apps can be launched. The alert is "You cannot use this version of the application Terminal.app with this version of Mac OS X." Any hints?
