On my Galaxy S3 on Sprint I noticed I wasn't able to update my PRL, profile, or Samsung files. Apparently something is wrong. I'm running PDA:MK3 / PHONE:MK3 / CSC:MK3 (SPR) rooted with Oden 3.04. I have titanium backup pro on the phone. I was going to wait to update to 4.4 I just haven't seen a stock or daily driver 4.4 rom yet.
