Well, I've been tinkering a little more and so far have not had any success with backing up my radio. I was able to run the OS, ExtROM, and ROM back ups - but I received checksum fails after each completed. The SD card has been working great, I have been using it constantly in my phone since I got it. When I try to explore it (in a card reader under Vista SP2), I get the 'Card must be Formatted First' dialogue box. What gives? Bad card, maybe? I doubt it, but I don't know why I keep getting the checksum failures in MTTY.
I attached the log if someone could please look at it. Thanks for any help, in advance!
