I have heard some complications about upgrading to 4.3 and then rooting and not being able to unroot and go back to stock samsung. Any help would be great. Odin has been failing and I just feel stuck. How can i unroot and go back to 4.3 on my galaxy s 3? Thanks in advance and sorry if this has already been answered. I am just having a hard time getting everything in order.
Welcome to the forum! This should really be in the Q&A section. Also, if you'd searched the forum, you would have seen, at least, a couple of threads that can help you ...
Guide to returning to stock 4.3 via custom recovery
Guide to returning to stock 4.3 via Odin. Please go to the last pages for the single Odin flash-able file
Either option would return your phone to factory stock ROM, unroot and install stock recovery
