I did watch the video. If you are not rooted, I doubt it has anything to do with /persist.
My suggestion is to flash the entire stock SBF file for your carrier. This is possible, even with a locked bootloader because it is signed with release keys.
Follow the instructions in the "Return to Stock" thread (I suggest using the manual method), and let us know if that solves your problem.
SBFing back to stock can actually repair a corrupted filesystem - a factory reset can not.
This is your best bet to fix the issue. If you try and it does not work, likely you have a hardware issue.
