First you will have to root it and get a recovery, I suggest you read http://forum.xda-developers.com/show....php?t=2569904 and http://forum.xda-developers.com/show....php?t=2593918
then look into keeping root on a locked bootloader or unlock the bootloader.

The instructions have been written down more times than I care to remember, please read them.

I'd like to report that the flashable zip and stripped FTF for the C6806 work fantastically!

Such an easy process to upgrade.

Everything seems to be working great so far; Xposed is up and running and the phone seems to be a tad smoother, if that is at all possible.

Thanks so much again!

In terms of an instructional video - it really is not required.

This is why people are sooo confused: a post that says you can only install custom roms on UB..

WRONG!!!

You can only use custom kernel on UB, custom roms ok as long rooted and has recovery.. (see the many many posts on this - as @blueether said, written more times than I care to guess....) therefore, anything that can use stock kernel (eg nut' stripped ftf) can be flashed on LB (if rooted with recovery).

Back camera not working after upgrade. Front Camera is good. Any fixes or ideas?

Mine was C6802 Locked Bootloader with rooted 14.2.A.0.290.

First, I upgraded XZDualRecovery from 2.7.78 to latest 2.7.123.

Then, I backup in TWRP and flash 2 files.

All the data and settings are still there and only the back camera is not working.

Do I have to wipe Dalvik cache and data and retry flashing?

Or, is there any other FTF from another Region for retrying?

Thanks.

Clean flash it. I still don't understand why people still continue to run the risk of Dirty Flashing. Yes it works sometimes, but other times you will have issues. Clean Flash always guys.

Thumbs up Sucess upgrading from .136
Hi everyone:

I'd like to report success in upgrading my C6833 from a rooted .136 with locked bootloader. Preparation was the key point here:

A. Preparation:
  1. Activated USB debug and installation from unknown sources.
  2. Backup using TWRP and Sony Backup app.
  3. Updated TWRP from 2.6 to the lastest 2.7.123. Got it from NUT (ZU-lockeddualrecovery2.7.123-BETA.installer.zip) and used TWRP to install it. Then I reboot to the new TWRP.
  4. Updated flashtool to 0.9.16 (the latest I could find). Note that 0.9.14 does not work (I tried).

With all this in place, I was able to upgrade:

B Upgrade
  1. Boot into TWRP.
  2. Wiped Dalvik-Cache, System, Cache. This is important to avoid boot loops and the camera not working problem. Did not wipe Data nor Internal Storage.
  3. Installed Sony Xperia Z Ultra Europe LTE14.3.A.0.757__flashable.zip (original link on the OP).
    Do not press reboot. Go to the main menu, then Reboot -> Power Off.
  4. Flashed C6833_14.3.A.0.757_EUR LTE Stripped..ftf (original link on the OP).

During reboot, the system detected it was an upgrade and was restored from backup. As far as I can tell, I did not loose any apps nor settings.

Note that these instructions are just a repeat of what was posted by others, they are not created by me!

Note also that I started with a rooted phone, with TWRP installed. If you start with a stock, you'll have to go back to 532, root that, and upgrade to 757. This has been explained somewhere else and links have been presented. For example, here.

Big thanks to chemcup for the OP and files!
