Sorry I know you guys get common stuff like this a lot, and as such I searched for my issue but everything I found lead me to a dead end.
I'm currently using VZW Galaxy S4 (SCH-i545) with build VRUDMI1 and android 4.2.2
I had disabled OTA updates by using a guide about a year ago. I'm needing to unroot my phone and put it back to stock so I can get OTA and move on to 4.4 (I don't know enough about custom roms and flashing to do it without OTA).
From what I read, I need to use odin to flash a tar file while in download mode. Problem is, I don't know which file to get. I've looked at some guides but I can't find a working link for an SCH-545 VRUDMI1 with 4.2.2
Any help would be appreciated and thanks for your time.
