Thanks

I guess I am a lot stupider than that... that doesn't really answer my question... 1. How do I back up the data.zip and sys.txt files? Just drag those two files to my spare SD card? 2. How do I back up the entire flash disk? 3. If I do copy the data.zip and sys.txt, (or the entire flash disk for that matter) and I eventually have problems, do I just replace the "bad" data.zip and sys.txt files stem with the two I copied for back up or what? 4. If I had "copied the entire flash disk" onto an SD card, can I just replace the bad files with the entire copied disk?

I have an F90bt and would like to attempt mods... I see that it is emphasized heavily to "backup files" before doing any mods but I can't find a post that explains exactly what to back up and how to do it and how to return unit to original settings... Exactly which files should be backed up in order to return all to factory settings? What is the best way to copy the necessary files... do I just drag those files to the SD card once in Test Mode then set this SD card aside? Then, in the event I want to return my unit to factory settings, do I just put this SD card back in the unit
