Hi all, I just recently got a Z2( first sony device in almost 10 years). It is on 23.5.A.0.575 build. I guess it is still locked bootloader.
I am wondering if anyone could give me a general idea of what to do to root, unlock bootloader( if it is necessary), Recovery and install rom.
I have been tinkering some other android devices and I know how to backup/install rom. But with so much info floating around the forum I kind of lost direction of what to do for the z2.
I appreciate anyone's input.
Thank you.
attachment is the phone infomation. I am in the U.S. and using AT&T as my wireless carrier.
Install all the required adb drivers first for Z2
I suggest u downgrade first to kitkat using flashtool then you need to root and install recovery.

Thank you so much, hariskh. I am reading all the threads you gave me now.
One quick question, someone else mention downgrade to LP 5.1.1. Is there any difference if I downgrade to KK or LP? I would for sure install a MM rom on top of that. Will the downgraded firmware matter?
Again, thank you for your help.

its your choice you want to do now or later but sometimes after unlocking your bootloader your phone factory resets including internal storage.I suggest do it now but first do a TA backup first. it will backup your TA partion and whenever u want to lock your bootloader without losing features u can do it with this tool and no one will ever know that your bootloader was ever unlocked. its very useful backup first

Hi there,
I'm new to this world, i've an z ultra with 14.1.B.1.510 with locked bootloader, i've no notification for new update...
I don't need to flash costum roms, just the stock kitkat one, but i'd love rooting to use titanium backup and a few more programs.
It's the better to root with my actual rom or should i update first and then root~?
It's mandatory that i unlock the bootloader?
What's the best/simple way to root this device?
Thks
You don't have to unlock your bootloader to update to stock 4.4.4, you either download official PC Companion software and it will tell you that there is an update for your phone, or download Flashtool install the drivers included in Drivers folder and download a 14.4.A.0.108.ftf flash it through Flashtool and you are done

And about rooting? What's the simple method?
if you root before updating, you will lose root, you should update and then root your device, use Towelroot, it works flawlessly on the aforementioned ROM "14.4.A.0.108" I used it my self; Good luck

Access to /system rw
Requirements
USB debugging enabled
Settings => About phone => Click 7 times on Android Build to unlock developer options
Unknown sources enabled
Settings => Security
adb drivers installed
How to use

Rooting Pre 4.4.4
Upgrade to one of the 4.4.4 FTFs listed above to save any hassle
Rooting The GPe
GPe Owners: Do not try and flash any FTFs to your device. You will BRICK it with no way to recover it.
Go to this thread and follow the steps.
Back up TA Partition:The TA partition is the "Trim Area". There are lots of things stored in here like root certs, revoked certs, DRM keys, current firmware version,... the list goes on. What we are concerned about here is with the DRM keys. Some service centres will not service a Sony device if these are missing. Unlocking the BL will erase these.
Once you lose these keys, you can't get them back, so backup the TA and upload it to your Dropbox etc
You will need Backup TA for Sony Xperia by @DevShaft Please read the thread.
Instructions:
Download the latest version of Backup TA.
Extract the ZIP file to a folder location of your choosing.
Navigate to the folder location of Backup TA.
Make sure no other script or application which is using ADB is running.
Make sure the device is booted in normal mode (the way you normally use it).
Run Backup-TA.bat
Read the last paragraph of the license before continuing.
Read the information and follow the instructions given by the tool.
Don't forget to make a donation or thank the OP in the original thread
Install Recovery:
Download the latest version of @[NUT]'s Dual Recovery
Instructions:
Make sure you have USB debugging turned ON.
download ZU-lockeddualrecovery[VERSION]-BETA.installer.zip from http://nut.xperia-files.com
Windows:
unpack at C: or somewhere you will remember!
navigate to the resulting directory and look for install.bat, double click it to run;
Linux:
unpack in your home folder with 'unzip ZU-lockeddualrecovery[VERSION]-BETA.installer.zip'
navigate to the resulting directory and 'chmod +x install.sh', then execute it, follow instructions.
Your phone WILL reboot when installation has completed and it will go into the default recovery for the first boot.
Reboot to system from recovery to allow the installer to clean up after installation (it is safe to skip this step).
Enjoy DUAL RECOVERY!

Unlock the Bootloader:This will wipe your phone, so backup your stuff
You only need to unlock the bootloader if you want to run either a custom kernel or a custom ROM. Most ROMs based on the Sony releases will run on a locked bootloader.
Instructions:
Go to Sony's Developer site
Request the unlock key and check your mail straight away. Email is quick these days.
Open the latest Flashtool on your computer
Click the "BLU" icon
Follow the steps and enter your unlock key
Install Custom ROM:To install a custom ROM you will have to complete the steps above (ROOT, Back up the TA Partition, and Unlock the Bootloader) you dont need to have installed recovery but it will help you make a backup of the current state of your device.
After the above are done:
Backup current software with custom recovery (TWRP or cwm - use the same recovery the the new ROM uses*)
Downlod ROM
Extract boot.img from within the .zip
Flash the boot.img (not absolutely necessary but will mean you are on a recovery that is tested to work with the ROM)
In fastboot mode use either flashtool or the fastboot commands
- If you want to use the boot.img's recovery to make a back up of the current software/state of the device use:
Code:
fastboot boot boot.img
- or if you just want to flash the kernel and recovery to flash the ROM use:
Code:
fastboot flash boot boot.img
fastboot reboot
Wipe Data
Wipe Cache
Wipe Delvik Cache
Flash ROM
Reboot
*CM based ROMs normally use CWM. Slim and Omni based normally use TWRP
Using flashtool:Please use this very good guide: Flashtool XZU
Back to Stock:
To get back to pure stock Sony there are several things that need to be done:
Make sure you have root
Backup any data/photos/etc on the phone
Restore your TA backup with the TA backup tool above
If you are on a custom kernel or ROM you ZU will not boot at this stage
Start flashtool and load a FTF
Start the flash and wait for the onscreen instructions to connect the ZU
Connect your ZU in flashmode
With the ZU powered off
Connect to PC while holding the volume down key
Flash will start
Wait for flash to complete

As always, very informative blueether.
Questions:
(1) Does this mean we no longer need to downgrade/upgrade/restore imei etc?
(2) Unlocking the bootloader is a requirement for installing any rom? No way around this?
(3) I understand the need for the disclaimers but rooting/unlocking BL doesn't automatically void your warranty does it?

1/ was only needed on 4.2
2/ added a line
3/ ring Sony and say this: "I rooted my ZU, and now it won't boot. Can you fix it for me?" what do you think their response will be?
With the warranty question: I asked because I'm more concerned about the cracked glass issues than bricking the device because I couldn't follow instructions. Thanks again for the instructions.
I may sound dumb but if I am only interested in root just for link2sd feature & foldermount to overcome internal storage limitation by transfering to SD card then do I have to follow all steps ? or only first 2 step will do i.e. Root & install SU.
I will just root it & don't want to touch TA or Bootloader as not planning to update with custom rom. please suggest that even for rooting do I need to backup TA / unlock bootloader.
also will new update of Android Lollipop will wipe my root or will I be able to upgrade to lollipop in later on stage with Root.
please reply on this.
Nice with an updated version. Do speak up if you need some help with anything.

My XZU hasn't arrived but my experience with other phones is that root alone should allow you to use link2sd and fouldermount.

Yes if you just need root the only go that far
OTA will probably fail with root, and flashing a FTF will wipe root when L arrives
rooting is not working. stops as there is no tr.apk included. In the guide there is nothing about tr.apk needed to be downloaded as well as that you need to donate before you can download. I dont mind to donate but I need to know it will work.

I am pretty certain that you have to go back to stock to receive the OTA, but I think that would apply also if you only rooted. Flashing an ftf file with flashtool without checking the boxes to wipe data is what I have seen recommended to get back to stock. I hate giving an answer I am not one hundred percent sure is correct so I will call on some experts, @blueether or @HEPennypacker can you confirm this is correct please.

unless the OTA is only very minor it will normally fail even if the ZU just rooted

Hi guys.
I really took my time and I have searched the whole forum, all the threads involving rooting and also googled the heck of it, but still I am not pretty 100% sure how should I root mine Z2 23.0.1.A.0.167 after update as in many threads I found different answers.
Could please someone point me how to root my Z2?
Specifications below:
- first time root
- no custom recovery
- bought as 4.4.2, now updated to 4.4.4 @23.0.1.A.0.167
- UK, unbranded
I would like to get root, have custom recovery, could flash custom roms/kernels, etc.
I will really appreciate any help.
Thanks.
1. Use flashtool to downgrade to 314 firmware (exclude data)
2. Root and install recovery
3. Flash 167 rom
4. Useflashtool to flash pre-rooted 167 firmware (excluding data and system)
This method would alow you to keep your bootloader locked
I recomend using the TA Backup tool to backup ur TA just incase you want to unlock your bootloader
(when you root your device on 314)

I thought you can easily unlock bootloader via Sony code, as I checked mine in software info I would be able to do it, or am I wrong?
In case I have unlocked bootloader, I will just flash via flash tool for example the dual recovery, then flash prerooted rom and I am good to go right?

One more question, any way to get root before flashing whole rom so I can run titanium backup before I wipe the whole thing?
Get your backup before the process.

This post shows you how to upgrade your system to lollipop 5.1.1 and optionally have root privileges. This is tested on C6833 model. For other models see the troubleshooting section near the end of the post.
Requirements:
Flashtool 0.9.18.6. or 0.9.19.6 or higher Important: Do not use Flashtool 0.9.19.0.
If you want to root the phone: Rooted XZU on Android version 5.0.2 or Kitkat with custom recovery installed.
This works on locked or unlocked bootloaders and any customization.
Download link for upgrade only:
C6833_14.6.A.0.368_1275-8026_R2D.ftf (unmodified Customized DE):
https://mega.nz/#!khF1nILD!C5D70e-BjCKVBCuOurjFOLcIMZDcldYVeIDnFiR-PGM
Download link for upgrade and root:
5.1.1-system.zip:
https://mega.nz/#!YoFgCSjA!Zh8t_4jeXcAEWhOYePA40uQLI7vw4-CnxohjBdMbpz0
C6833_14.6.A.0.368_No_System.ftf
https://mega.nz/#!l4dllSTT!R393EG4W3CwOZp1OLOzfUzpHF0IlvsmfW04BrGOggXc
Instructions for upgrading without root:
1- Back up your internal SDCARD and your apps.
2- Download C6833_14.6.A.0.368_1275-8026_R2D.ftf
3- Open Flashtool and click on the flash icon. Choose flash mode.
4- Navigate to where you saved C6833_14.6.A.0.368_1275-8026_R2D.ftf and flash this ftf with your phone in flash mode. I recommend wiping apps and cache and data (Note that wiping data will erase your internal SDcard too). To put your phone in flash mode, hold the volume down button when it is off and connect with the USB cable to the PC.
5- Reboot.
Instructions for upgrading with root:
0- If your existing system is rooted using Kingroot read the troubleshooting section below before continuing.
1- Back up your internal SDCARD and your apps.
2- Download C6833_14.6.A.0.368_No_System.ftf and 5.1.1_system.zip.
3- Copy 5.1.1-system.zip to your phone's internal SDcard.
4- Reboot to recovery and install 5.1.1-system.zip.
5- If you are coming from Kitkat just Turn the phone off. If you are coming from 5.0.2, reboot the phone and let it work through the boot animation which will take a while. Then it will show force closing messages and possibly reboots itself. At this point turn it off by holding down the power and volume-up keys for a few seconds. The phone will vibrate 3 times and turns off.
6- Open Flashtool and click on the flash icon. Choose flash mode.
7- Navigate to where you saved C6833_14.6.A.0.368_No_System.ftf and flash this ftf with your phone in flash mode. I recommend wiping apps and cache and data (Note that wiping data will erase your internal SDcard too). To put your phone in flash mode, hold the volume down button when it is off and connect with the USB cable to the PC.
8- Reboot.
Troubleshooting, etc.
This procedure works only if you follow every step carefully. When you are done you can easily test your root status in a terminal emulator or via adb. Please see the attached image.
If you have used Kingroot to root your existing system flashing this ROM may not work and it may leave your system with a partially updated file system that may be broken. The reason is that Kingroot (which in my opinion is malware) makes some of your system files immutable which means they cannot be removed during a software upgrade. To proceed, you should either find a way to replace this horrendous piece of code with SuperSU or downgrade to Kitkat and root with XZDualRecovery before trying this guide. Read the second part of http://forum.xda-developers.com/showpost.php?p=62936808&postcount=22.
If during the procedure for root the flashing of the ftf in step 7 fails, repeat step 7 with C6833_14.6.A.0.368_1275-8026_R2D.ftf or any other 14.6.A.0.368 ftf but exclude the system partition in the flashtool dialog window. If you don't exclude the system partition you will not get root.
If you have root after the procedure but something else doesn't work, try a factory reset.
Note that flashtool 0.9.19.0 was specifically released to support the new sin format on new devices and some of its features don't work with older devices. So to avoid taking any chances I used version 18.
I don't know if this works for C6802 or C6806. Some users reported success on 6806, like this one and this. For that model you follow this guide and use the zip file posted here. The only difference is that instead of flashing the ftf posted here in the next step, use the stock 14.6.A.0.368 ftf for your phone and exclude system.
Will this C6833 FTF work on a C6806 USA phone?, because I can't find a C6806 FTF anywhere...
Can this system zip be used with other customized versions of c6833 ftf.

could you share flashtool 0.9.18.0 cos I can't find that version only higher.
will this work on c6802 just wondering?
I did as you said but. I see no super-su

You probably didn't exclude the system partition in this step:
7- Navigate to where you saved C6833_Customized+DE_14.6.A.0.368.ftf.*Exclude system partition*and flash this ftf.
Out of curiosity, what is wrong with the latest flashtool?

Customized DE just means it is the German version of the ROM. I used that because I bought the phone in Germany. But the menus and keyboard and everything is in English so you would not even notice the difference.
This method will not touch your bootloader status so if you are locked you remain locked.
If you are already on 5.1.1 through OTA this will not work for you. You need to start from rooted 5.0.2 with recovery installed.

I think you can still do it straight from kitkat but if you are following the instructions with root in step 5 instead of rebooting just turn the phone off.
Let me know if that works.
so my ZU used to be rooted with Lollipop 5.0.2, but i removed Kinguser/chinese root app and no longer have root access. I've also previously installed recovery but don't know if it will still work ? i forgot how to boot into recovery to see if it even works.. any helpers?
Power on the phone and when u see the led notification start pressing either the Volume UP or Volume Down key a couple of times to make your phone boot into recovery mode

Hello dear friends.
I'd like to root my Xperia-Z2 locked bootloader stock rom untouched without downgrade
Is there any preroot ftf file can flashing via flash tool directly?. If not what is the easiest way to do it without unlock bootloader?
Thanks

Excuse me, he would say it, but this is another topic with a question, how to root Android Marshmallow with locked bootloader.
With Flashtool, no way to flash prerooted FTF, because prerooted firmware in ZIP format is only for flash from recovery (TWRP).
As already understood, at this stage it is not possible to root with locked BL.
Do not you want to unlock, but you don't want to do downgrade.
You are interested in the easiest way without unlocking, but in this situation (without unlocked bootloader) for now is only possible to return to a previous version of Android, which you do not want.
Consider and choose possible and reasonable option for you.

My phone still in warranty I don't want lose it.
How can I do downgrade and upgrade again to root MM . 575?
Sent from my D6503 using XDA-Developers mobile app
Step.
1. Download right FTF firmware for your model device, that software have way to root, like 5.1.1.
2. Install drivers for device and flashmod, after that Flash firmware from Flashtool.
3. After that, root Android version and install recovery - Nuts Dual Recovery.
4. When you have root and recovery, just follow step for install in recovery / clear data, cache, dalvik cache ..../ from first post in topic with prerooted Marshmallow .575 and you will be with rooted last version on Android, Marshmallow 6.0.1, build 23.5.A.0.575
@Monipeev Many thanks
Can I rollback to stock rom anytime ?
To cover warranty

Yes of course.
You just have to know the number by region (Customization version) of your stock software.

Sorry for the late reply, too much work today.
Probably everything is OK for now, if you repeated the necessary steps for this again.
I think you missed a step or your flash incorrect file.

I think, you forgot to flash TWRP Recovery after flash the rom.
TWRP app, will not help in this situation.
Think it's best and clear to move back to return to the previous version of Android which allows Root, then install recovery again and again steps to flash pre rooted Marshmallow.
Sorry for this, but at least I would do.
P.s. I see too late, that you forgot to flash recovery on the moment when you flash the rom.
I didn't find flashable recovery zip to flash via recovey before lose the old recovey on old firmware
That's mean I have to redo all these steps again?
Ok if I did return the steps how to install this recovery after flash the rom?

@Balage3000, Why you try dual recovery?
If you Install Android Marshmallow, dual recovery don't work on it for now.
I have not read yet, someone managed it installed on this version of Android.

Unlock Bootloader? Sorry for the bad english.
@Balage3000, The Rom's that you mention are installed precisely device with unlocked BL. In their description is given this information. If you try it on locked bootloader, they will not working.
