it has now been said about the bootloader and checking etc, so lets now leave it and move on or this thread will just go further off track than it kinda just has.
I find it amazing that sony would have the bootloader unlockable on their site with the camera issue personally. They can put disclaimers up left right and centre but that doesn't really help the fact that they, by offering, are endorsing potentially breaking your camera with no chance of a fix currently.
rumours from 4.3 to 4.4 automatically curing that are to be read in places, and some people with "sources" in sony stating ademantly that it WILL be fixed, and others saying it wont.
when stock and modded stock is beating seven shades of shizzle out of the rest of the competition, then for now, why bother?
mod the phone and a lot of what you want to do will be possible
