I have tried googling it but no luck.


Only way for me to root is to unlock bootloader it seems.


EDIT; I got root access!!

I unlocked the bootloader via flashtool. I still have bravia engine/camera/etc.

Details! :):beer:

Sent from my Nexus 5
here are the steps I did..I will do my best to provide anything I can.

First thing; unlock the bootloader. I unlocked it via flashtool. i still have bravia engine/clear audio, so that's intact. Put the SUPERSU 2.40 on your SD Card along with the dual recovery flash file from http://forum.xda-developers.com/t2-ultra/development/t2-ultra-xzdualrecovery-qa-t2823793

After that I used fastboot to install the CWM recovery( fastboot.exe flash recovery boot.img), and rebooted.

I rebooted into CWM and flashed the dual recovery. follow the instructions to boot into TWRP(I like this recovery.)and flash SUPERSU 2.40. Wipe cache/dalvik/system. If you get a bootloop, reboot into recovery and flash the pre rooted stock firmware from here; http://forum.xda-developers.com/t2-ultra/development/t2-ultra-d5303-4-4-3-pre-rooted-stock-t2962677. then reboot.


another fun fact? I also successfully backed up the TA Partition. woo!

What file did you flash at first? Is it T2U-SS_DooMLoRD_AdvStkKernel_FW-207_v01.img ?
It didn't work for me, I could not reboot into CWM or whatever custom recovery it contains.
Thank you!

Sure.


BEFORE ANYTHING; Put supersu 2.40 and http://forum.xda-developers.com/t2-ultra/development/t2-ultra-xzdualrecovery-qa-t2823793 on your SD Card!!


I used flashtool(http://www.flashtool.net/downloads.php)to unlock the bootloader first. I still had my TA Keys so it should be fine.

after unlocking the bootloader, reboot into fastboot mode(I think it's while the phone boots up, you hold power+up vol). and use this; http://forum.xda-developers.com/showthread.php?t=2685932 to boot into CWM recovery.

Once you're in CWM, Install the dual recovery and reboot phone. Hold down vol when the green LED turns on, you will reboot into TWRP. Touch controls won't work but if you press the power button and press it again, touch works.

Install SuperSU 2.40 and you should be okay..

That kernel works on 4.4.2? in the CWM thread right in the first post it says requirements 4.3. Need more details before I move forward with this.
I am on a US D5316 running 4.4.2 , build 19.1.A.0.486.
