[Q] Need root to delete wrong APN?
I recently bought a used AT&T Galaxy S4 i337 that came with 4.4.2 and NC1. I have a Net10 SIM in it and everything works save for MMS messaging. I created a new APN with the correct Net10 settings and selected it but the AT&T APN is greyed-out cannot be removed and appears to still be in use in regards to MMS (there's a little box that says "Turn APN on/off" that can't be unchecked).
I've been scouring this site for the past few days an cannot find a solution for just deleting a "locked" APN from this phone. I was hoping to find an easy solution but everything points to downgrading to get root and then manually deleting of editing the offending APN? Need to get this working regardless so it doesn't matter how difficult this will be.
Any help or thoughts would be greatly appreciated.
