I'm hoping to flash the stock rom back onto my device so I can update the PRL. I downloaded the file on samsung-updates.com. The file that I download was found "Firmware archive" for Sprint's SPH-L720 (Galaxy S4).
A comment said the SPR was for regular users and the XAS one was for engineers. Not exactly sure what that means, but I downlaoded the SPR file changelist 1927016
Now when I look inside I have two files,
What does these files do? Why do I do with the .dll? How do I flash my device with it? Do I simply load the .zip into Clockworkmod and boot up? Should I, or should I not wipe cache and Dalvik after I do that? I've already backed up my current version of CM and data using CWM.
