I made an ftf for 14.4.A.0.108 Android 4.4.4 for the 6833 (cda# 1275.9426). I think this makes it an unbranded generic rom from Malaysia, anyways, I have confirmed it all works well.
Update: Deodexed Patch (Post 2) also working well.
Update 2: Dark Themed Deodex Patch (Post 3) working even better!
To make the ftf I grabbed a pc companion update and converted it with flashtool.
Titanium backup first as there will be a full wipe. Nandroid probably a good idea too
Flash attached ftf in the latest flashtool (remember, this will wipe everything). Enough guides on how to do this already exist so we don't need another..

Boot and set up. Don't forget to enable usb debugging in developer options after tapping Settings ~ About Phone ~ Build number x6 times.
Root will Easyroot v9 (fixed version) ("customised for Xperia" version of Towelroot - includes ric kill ftw)

Load supersu (chainfire version) from play store and update binary when prompted.
Install @[NUT] dual recovery. Note: This download seems to annoy chrome and throw up a virus alert ~ use the zip anyway it's safe.
Updated version: http://nut.xperia-files.com/download...RhbGxlci56aXA=
You can now flash the deodex patch in Post 2 or Post 3 if you would like
Titanium backup you did earlier should be good for you to restore from.
Remember to refix your sd card via the sdfix app from play store. The rooting tool you used earlier already performs ric kill so root r/w access is ok
a bonus for you:...
(note on screenshots that custom stuff thru xposed is working)
Confirmed as working xposed installer : https://docs.google.com/file/d/0B0uD...p=docslist_api
Confirmed TWRP backup after installing dual recovery.
Ndr Utils for rebooting (thx @[NUT]) [installed with dual recovery]
