JUst curious if there is a way to go back to 4.2 from 4.3? I ask because I just got my replacement phone from Asurion & it already had 4.3 installed. As we all know 4.3 MJ9 has the bootloader locked & we have to use SafeStrap to flash roms. It's working great but I would prefer an unlocked bootloader (wouldn't me all!!)...is going back possible? Odin maybe?
