I just rooted and backed up my nv I also created a nandroid backup. I'm on the stock rom still but i'm about to try out some new roms my question is since I have a nandroid of my stock rom should I create a nandroid everytime I switch roms or will my nandroid of the stock rom be fine if i ever run into any problems. I see some people lose 4g and other issues with roms so I don't want to start flashing roms until I know this.
