It is completely stock ROM with xposed and gravitybox installed. Apart from that, its pure stock. Even at that the only things I have activated with gravitybox is the notification shade and circle battery mod. Nothing has been touched in way of kernels, radios, WiFi, telephony tweaks etc. Really don't fancy having to reset my device entirely, thanks for the suggestion but I'm not planning on restoring it back and setting it up all over again. As for the WiFi suggestion, it worked for 3min 27sec (yes I timed it) but then, low and behold, the orange bars were back. I've been reading on some Google forums that its an issue in 4.4.2 but it was working fine prior to me rooting. I even put it in to safe mode to see if it was an installed app that was affecting it but that turned up nothing.
