I apologize if there is a thread already covering my question, but I have been searching for hours and have not found a definitive answer.
It is said that making a nandroid backup is taking an "image" of your phone at that particular moment in time. My question is are there any possible modifications that are done that would not revert back to the way they were after restoring a backup.
Ex. build.prop files altered through droid overclock ap, or deodexing.
I have not gotten into custom ROMS yet for fear of getting in over my head. However, I would love to have just a black notification bar for now. I believe that I need to deodex for that mod. It was a nightmare for me to update to 2.3.340 because of changing some build.prop files and I don't want to go through that again. Especially if that next update is Gingerbread.
Thank you for any help
