I am switching to Sprint in a few weeks and getting an S3. I believe they have 4.1.2 on them now? Anyway, I would really like to be able to update/flash STOCK 4.3 onto it. I am not new to rooting and flashing other devices (like motorolas), but have had a lot of trouble with a galaxy 7.7 tablet (I bricked it).
Could someone please tell me what I need to do?
Do I need to root first, then use odin to install stock 4.3?
Thank you so very much!
