For my 04.5 LLY, I wrote up a tune for my truck, modifying the OS file I have loaded on it now. When I went to flash the new tune it gave me error $0595 about firmware compatibility on the handheld during the flash. Any idea about why I can’t flash it anymore?

Sounds like you need to update your device.
What version of EFILive are you currently using to modify files?
