I got another Evo for someone else and it was already rooted. But on the downside it had Clockwork Recovery. So I downloaded the appropriate Amon Ra zip file and put it on the root of their SD card. I renamed it PC36IMG.zip and also put another copy on the root of the same file renamed PC36IMG (no .zip). Rebooted into bootloader and it says there's no file to update. Is this because of how the previous owner of the phone rooted it? Or is there maybe another way to install Amon Ra?
