I've brought my device back stock, sitting on 4.2.2.
However it doesn't want to take an OTA for whatever reason. Seems to be a device issue based on a search on google, but I was curious, since I have the OTA files for the 4.3 update and 4.4 update, why not just push them manually? Doesn't seem the stock recovery allows for an option to install from internal storage. I mean, there is an option to select, but all it seems to do is retart the phone.
You help is appreciated, even if this is a noob question.
