Okay, I did some looking around, and found this site:
How to create a full backup (Nandroid) of your HTC EVO
I tried following the directions, but I didnt see the word nandroid on the screen this guy speaks of.... so heres what I did so far, and I wonder if this was the right choice: I downloaded quick boot from the android market, I brought it up, and chose recovery, which then rebooted my evo, and I looked over the choices: reboot system now, usb-ms toggle (not sure what this is), backup/restore, flash zip from sd card (dont know this one either...is it a rom thing?), wipe (I have a pretty good idea what this is: formatting?), partition sd card (I understand this), other, power off... I chose backup/restore, then I was presented with more choices: return, nand backup, nand + ext backup (no idea, unless ext means exit?), nand restore (this must be if your evo pukes), backup google proprietary files (dont know this), restore google proprietary files (restore the thing I dont know, lol)... I chose nand backup.... did I choose the correct one?
