That would certainly be an option but unnecessary. Why not just flash an updated ROM? What you just said would be a very tedious way of going about it....almost as tedious as throwing your phone in the trashcan and buying a new one....I am being facetious but trying to make the point...


.
Many times, just accepting the update will cause you to loose root so no need to go thru the hassle of unrooting....just flat out accept the update....and then wait WEEKS for the devs to catch up to the low priority of people that did it that way. Their first priority is for people that retained root and to get a new new ROM out to them to flash. This is why rooting is so confusing to the newbie. Because so many people are on different base versions. The idea is to stay rooted so you can keep up to date with the devs and work with the "top priority" group...for lack of a better phrase. Anyway, I am EXTREMELY new to this so take what I have to say with a grain of salt.
