Special features:

In the following guide I suggest you use an external SDCard but that's just good practice, you can use your internal storage or even an USB OTG storage device in TWRP if you like to install, that's no problem!... If you are modding and the likes, best is to have an external sdcard, just for safeties sake.

If you are unable to download torrent files directly, have http://zbigz.com/ do it for you!

C69XX_14.3.A.0.681.patch.zip (9.15MB)

Download, unpack, run the install.bat and follow instructions.

For anyone who runs in to issues using the patch installer, take the zip file from the files directory and try to flash that manually.
How to update to 14.3.A.0.681:
  1. Files:Save them somewhere you remember;
  2. Put 'C69XX_14.3.A.0.681.flashable.zip' on (the external) SDcard1;
  3. Put 'C69XX_14.3.A.0.681_Stripped.ftf' inside the Flashtool/firmwares folder;
  4. Create a backup of your phone in TWRP and don't forget to backup the contents of 'SDCard' (the internal storage!);
  5. Flash 'C69XX_14.3.A.0.681.flashable.zip' in TWRP;
    NOTE: do not reboot but go back to the main menu, then go to reboot->power off;
  6. Flash everything in 'C69XX_14.3.A.0.681_Stripped.ftf' using flashtool;
  7. Reboot to system.

The first boot will be slow and after some time at the boot animation you will see Android start optimizing the apps on your phone.

Enjoy! :laugh:

Known XZDualRecovery Issues:
Busybox Updater/Installer: If you have XZDualRecovery installed, un-install any Busybox updating app/tool as most if not all of them will install a version of busybox which does not support the lzma compression applets XZDualRecovery depends on. The version installed together with XZDualRecovery is very stable and I have yet to hear anyone complain about it's stability.

How to report errors:
Please, before shouting out "It doesn't work!!1!" or "I lost root!" or even "My phone reboots when remounting /system RW!!" try the following:
  • Restore any JB 4.2.2 FTF using any means you are familiar with so you can try again.
  • Root it using any means you are familiar with.
  • Install XZDualRecovery;
  • Update to 14.2.A.1.136;
  • Then try to update again using TWRP.
  • If it still fails something from there on: LOGS!!.
    NOTE: The important ones can be found in /cache/recovery and in /sdcard1/XZDualRecovery, pack them up and send them to me or attach them to your bug report.

Thank you :)

FAQ & Tips and Tricks

Camera problems?
You have 3 things to try to fix it, try them one at a time:
  1. Clear dalvik-cache only;
  2. Clear the camera app settings;
    • Do a factory reset in TWRP or PhilZ (this should keep your internal storage safe);
    • flash the ROM package again;
    • boot until you can test the camera;
    • If it works go back to recovery to restore a backup of data.

Easy switching between locked and unlocked bootloader states!
NOTE: USE TWRP ONLY for this guide.
NOTE 2: You NEED to have XZDualRecovery 2.7.43 or higher to make this work.
  • Create a backup, including the Trim Area (TA!)
  • Unlock your bootloader
  • Restore backup without TA
  • Create a new backup of your UNLOCKED TA
  • Restore the previous TA backup to relock your phone.

Done :good:

Now you can switch between locked and unlocked bootloaders quick and painless: no more system wipes and you can basically do whatever you want :D

How to enable init.d support:
Open a filemanager app and navigate to the location where the XZDualRecovery folder is located and go in to it. Open XZDR.prop as a text file and set dr.initd.active to true.

NOTE: For this guide ROM it means the init.d script called 99SuperSUDaemon will kick in to action, so it's best to disable (by setting chmod 644) /system/etc/install-recovery.sh for the time being or to clear it's contents.

Done :)

Downgrading to a 4.2 ROM:
Download C6903_14.1.G.1.534_[NUT].ftf (Bittorrent: 770MB) and flash it using FlashTool. I've also added the FTF to the downloads page on this DevDB tab, this will allow straight downloads as well.

This FTF will allow you to downgrade to .534 without loss of your IMEI :good:

Thanks to @mharckk and @MohammadAG for the workaround which contributed to the creation of this FTF.
