Hi all
this is referring to the following article but adding closure and possible solution: Power Mac G5 and Frustrating Open Firmwar… - Apple Community
While repairing my iMac G5, I faced the below error, a screen with this error flashing on the screen:
/usr/lib/libiconv.2.dylib - incompatible library version
sh requires version 7.0.0 or later, but libiconv.2.dylib provides version 5.0.0
I restarted the iMac, boot from OpenFirmware with CMD+OPT+F+O immediately after turning it on (don't wait for the chime) or grey screen).
After panicking I found: Mac Classic | Open Firmware Basics and Commands where I found the command:
multi-boot - Takes you to the boot selector which is otherwise accessible by holding the option/alt key while booting.
This opened the boot menu, that I wasn't able to open with any cd or DIR command in BootROM and helped me resetting the iMac.
Hope this helps someone else like me unable to find anything else online.
