Black screen after failed restore - G5 I tried to restore a G5, something went wrong and now I have this at startup:

dyld: library not loaded: /usr/liblibconv.2.dylib
Referenced from /bin/sh
Reason: Incompatible library version: sh requires version 7.0.0 or later, but      libiconv.2.dylibprovides version 5.0.0


Can anyone help please?

I don't have a Tiger cd as I was restoring using Disk Utility.  I;ve tried various methods for booting from USB but the G5 doesn't seem to give them any power at boot.
The resolution to my problem was somewhat messy. 

The black screen I mentioned was a result of a failed osx restore. It failed because of a bad dmg. The machine then suffered a kernel panic and I guess it was unable to roll back te changes it had made. 

I removed some ugly looking ram and cleaned te others, reinstalled osx from disk using a new drive and have so far not experienced any problems. 

Problem caused by dodgy dmg installation and dodgier ram
