New to Sony Devices - Xperia Z2 Q&A, Help & Troubleshooting

Ok so im by no means new to rooting and roms and the like since ive rooted every phone ive had over the last 5 years but for the life of me i can not seems to figure out these sony devices. So i downloaded and flashed the new 5.1.1 ftf thru flashtool last night and everything is working fine. I have google and searched thru xda about ways to root and i thought the first step would be to install XZdual recovery but i downloaded nuts installer and ran it which seems to have worked but it still does nothing whether trying to manually enter recovery or doing it thru adb. Ok guys what am i doing wrong? Any help would be great!

Must downgrade to 4.4.2, the XZDR will root and install a recovery, then you install a pre rooted package or modified but stock-based 5.1.1 ROM, you won't loose root or recovery; but you wont be able to update via "official" methods like OTA or PC Companion because you have modified the phone's software.
Step # 1 is downgrade to 4.4.2 (314 build number works like a charm)

Damn what a pain but thank you for the reply at least thats a start since there are lots of guides for rooting 4.4.2 lol. Thanks

You don't have to downgrade to kitkat, You can downgrade to lollipop 5.0.2 (by flashing a new ftf via flashtool) and root via king root and install recovery via xzrecovery app (after getting root access) and then follow these steps:
1.Download a pre-rooted firmware 5.1.1 (flashable zip)
2.Boot into Recovery (TWRP Recommend)
3.Install - Choose ROM direction - flash the ROM zip and wipe cache\dalvik cache
(don't worry this won't wipe your data)
# I highly recommend you to do a factory reset after flashing because if you didn't the phone will be laggy and battery will drain extremely fast
*And If you have xposed installed don't forget to remove it because it may causes problems
If I Helped, Leave A Thanks ?

If your going to downgrade to an older version of Android, why not go to a version of Android that can be rooted by an app that that doesn't require internet access or all the permissions of kingroot?
Kingroot requires a lot of permissions on your phone to complete something fairly basic.

flash older kernel in order to root latest firmware (23.0.1.A.0.167)?

Hi!
Somebody in a different forum suggested that it might be possible to root the latest firmware (23.0.1.A.0.167) by downgrading the kernel (http://forum.xda-developers.com/showpost.php?p=56590546&postcount=1224).
Can anybody confirm this method to work?
I purchased my Z2 tablet yesterday and was foolish enough to believe that I can upgrade to the latest firmware and still root my device (with a locked bootloader).

It doesn't work. You end up to bootloop. However you can flash prerooted firmware in custom recovery and have fully rooted device.

In order to do so I have to unlock my bootloader and with that I'm going to lose my drm keys, right?

No. If you easy root and install the dual recovery beforehand you flash from that.
But easy root doesn't seem to work with the latest firmware, they closed the vulnerability that easy root is using

Easy Root Tool works just fine with .314 firmware. So if you are now on latest .167 firmware, downgrade to .314, root it, install custom recovery and flash prerooted flashable.zip in custom recovery. Done.

Ah, I didn't know it's possible to downgrade the firmware
So I need the firmware flash tool and a ftf file of the 167 firmware, right?
And it can be done without root and a locked bootloader?
Sorry for all the newbie questions, I'm coming from HTC devices and it's a little different there

You need:
- latest Flashtool with drivers installed correctly for your device
- some working custom recovery
- Easy root tool
- ftf file you need is 314 firmware of you device where you have to downgrade to easily root it
- prerooted zip file included you device 167 firmware, SuperSu install files and latest dualrecovery install files.
You don´t need unlocked bootloader for this. Point of downgrading is to achieve root easily that you can have root with 167 firmware? Or do you mean that can you achieve root on 314 firmware without having it before? If so, yes you can with Easy root tool.

thanks for your efforts!
in the meantime I managed to downgrade the firmware to 314, successfully root and backup TA
I installed superSU from the play store and it is telling me that I need to update the binaries and I can choose between "normal" (which doesn't work) or through "twrp/cwm"
I didn't install any custom recovery yet, so I'm not sure how to move on from now
should I install dual recovery (from here: http://forum.xda-developers.com/showthread.php?t=2785598), after flash the latest supersu from recovery and finally flash prerooted zip file?
do I need custom recovery to flash the prerooted 167 firmware?
or should I just run the OTA to get 167 firmware (will the device still be rooted after the update)?
please advice

Good to here you achievment. If you can´t update SuperSu binaries by "normal" way easiest might be to flash SuperSu latest update from custom recovery. I recommend dual recovery from your link and when installed use TWRP.
So install dualrecovery, flash latest SuperSu and then prerooted zip. If you end up without write permissions to system here might be solution for that.

ota un-rooted y Z2!?!

Z2 with Bell Canada, locked bootloader.
Seems one of the forced ota updates has un-rooted my phone...
What is the best way to root it again?
Android 5.1.1
Build # 23.4.A.0.546
Cheers.
Same way you did it the first time I guess
Hi there,
With a locked boot-loader , you will have to flash an older root-able firmware ( think .134 ) in Flash tool . Root the phone, sure Towel root works, then flash a prerooted flash-able zip.
Or create a prerooted with PRFCreator.
downgrade to lollipop 5.0.2 (by flashing a new ftf via flashtool)and root via king root and install recovery via xzrecovery app (after getting root access) and then follow these steps:
1.Download a pre-rooted firmware 5.1.1 (flashable zip)
2.Boot into Recovery (TWRP Recommend)
3.Install - Choose ROM direction - flash the ROM zip and wipe cache\dalvik cache
(don't worry this won't wipe your data)
# I highly recommend you to do a factory reset after flashing because if you didn't the phone will be laggy and battery will drain extremely fast
*And If you have xposed installed don't forget to remove it because it may causes problems
If I Helped, Leave A Thanks ?

Had to roll back to D6503_17.1.A.2.55 to get it to root, now I'm just looking for pre-rooted firmware, any that you recommend?
Just download the latest bell ftf file (it will be what your ota version would be), and create a pre-rooted flashable zip using prf creator. Tutorials are here on XDA. They're very easy to follow.
I ended up creating a ROOTED update package from stock FTF
Seems to be all good now

Rooting Orange Z2 with locked bootloader

Hello, I recently bought an xperia Z2 from someone that had it from the french operator Orange.
Running on a heavily bloated lollipop 5.0.2 with a build number of 23.1.A.1.28 D6503 with a locked unlockable bootloader
Being a samsung user all my life, this seems a new territory to me, I first wanted to clean everything up and have it running on CM12, that seems impossible because of the bootloader lock.
Then I failed rooting it and got really confused. the device also doesnt boot into recovery AT ALL
Can you please help me root the hell out of it and clean all the crap that Orange put in it? and also would you please suggest a debloated clean stock rom(kitkat is preferred)
Thank you so much for your time, I'm looking forward for you replies
Use KingRoot for rooting,install BusyBox, then install custom dual recovery with XZRecovery finally flash SuperSU zip with recovery , here's a link for all the files needed http://www.mediafire.com/download/894tuibsb2a75bm/wts.zip
Well, my dear friend, I failed twice doing that, now im running a clean factory reset and going to try again, will let you know
Flash android version 4.4.2, root this version and then flash the firmware of your choice via recovery (make sure it is a prerooted one, that comes in a Flashable Zip form)
As I know, Sony devices doesn't have accessible stock recovery
You can boot into recovery only after installing custom recovery like :
TWRP - CWM - Philiz Touch

Having problems establishing root

A bit of background here:
I am trying to get setup for a fresh install of [ROM][LOLLIPOP][LB/UB][5.1.1] eXistenZ Premium | 7.0.0 | FINAL | 16/02.
As per that threads directions:
Fresh installation:
LOCKED & UNLOCKED Bootloaders
Flash latest rootable Sony's rom with flashtool (http://forum.xda-developers.com/show....php?t=2162907)
Root
Install NUT dual recovery (http://forum.xda-developers.com/show....php?t=2261606) or the recovery of your choice.
Reboot in recovery, Wipe Data, Cache and Dalvik/ART Cache.
Flash the rom.
Flash update if available.

So I am struggling getting a "lastest rootable sony" stock ROM working with root. All my tools are working just fine (ADB/Fastboot/Flashtools/PRFCreator) and bootloader is unlocked, I've just been out of this way too long. I can get a stock FTF file flashed but I just can't get root. I think I really just need to know which FTF to grab and which root technique I should be using for that FTF version. I've tried grabbing some older FTF's (KK) but I still haven't had much luck with root. The flashtools root techiques all give me the same "ERROR - Illegal key size or default parameters". With my understanding and past experience this really should be an easy task but it is definitely not being so right now.
Any specific advise I would really appreciate right now.
To be clear right now:
Boot loader is unlocked
Tools are working ADB/fastboot/Flashtools
No custom recovery
No Root
I can flash any FTF no problem
i get root with this method, downgrade to KK, root and recovery (root in KK is easy) then flash via recovery any custom rom, in your case eXistenZ
What version the firmware are you using and what root technique?
I tried a KK version and towelroot app. App reported root was achieved but it wasn't.
Going to try 23.0.1.A.0.167 which should be KK 4.4.4 from http://forum.xda-developers.com/showthread.php?t=2759934
Best root Method for kk 4.4.4?
Shouldn't be too confusing if you done it before. Basically you are going to flash a custom kernel with built in recovery and flash a SuperSU zip to get root before flashing your rom.
1. Download and flash stock Lollipop 5.1.1 FTF (either 232 or 264) with flashtool.
2. Download AndroPlus Kernel for Z2 here.
3. Flash with fastboot.
4. Download SuperSu zip and place onto SD card.
5. Boot into recovery and flash the zip. Reboot without wiping anything.
6. Download your ROM, in your case eXistenZ and place on SD card.
7. Reboot in recovery, Wipe Data, Cache and Dalvik/ART Cache.
8. Flash ROM and update.
9. Reboot and you're done.
