I just received my Sony z2 phone. (model d6503 17.1.2.a.0.314) I have tried every tool and rooting method on here to no avail.
I simply want to root phone, add SU and add recovery options.
Can you recommend a simple method that will work?
Is it possible to backup my original sony image before su and root?
Thanks a bunch.

Rooting vs Bootloader Unlock
Hello, believe it or not, many searches trying to figure this out has let me down a rabbit hole. I have a Sony Xperia Z2 (17.1.A.2.55) (v4.4.2) (Ker 3.4.0-perf-g46a79a0) with the bootloader Locked (and not unlockable). I am able to Root the device, after many attempts, (with TWRP) but have been having some difficulty installing custom ROMS.
My question is, do I need to unlock bootloader in order to install Custom ROMS or is Rooting enough?
When I try to flash CM 11 from TWRP Manager I get an error message saying that "Cannot install over previous version, device wipe needed".
Realising that this is very clear, I do not want to go ahead and wipe my device again only to have the install be impossible.
Any advice?
Cheers,
Philip,
I understand your frustration...seems like it should be much easier to root and backup the stock version of Android. Hopefully we can discover a technique to do same.

If you can't unlock your bootloader then that means that you cannot change the kernel to a non official kernel.
CM is not an option for you, but you will be able to use stock based roms
Is it possible to get SU access and still be able to get the Sony updates?
Is it wiser to go with another rom?
Do you loose any native functionality when going to a custom rom?
Thanks
If you have root you will still be able to update although when you do you will lose root privileges

Hey guys, I've rooted, installed CWM Recovery, Unlocked Bootloader, and installed CyanogenMod on another phone before.
The thing is, I've had this phone for about 6 months and wanted to do the same. However, after browsing through the forums, man are there a lot of scary sh*t going down. I would like the request the procedure to install CyanogenMod safely, without losing any Keys/IMEI/XReality/DRMkeys/Etcetera.
I dont know if the method given by FXP is supposed to be this straight forward, but I too like others, do not want to risk losing important stuff if it can be avoided (Keys/IMEI/XReality/DRMkeys/Etcetera).
HOWTO
Install instructions:
first time
- power off the phone:
- hold vol+ and plug usb to boot into fastboot (blu led)
- fastboot flash boot boot.img (from cm10 zip)
- fastboot reboot
- enter recovery, on boot led will be violet for 3'', during this period press vol+
- flash rom zip
- flash gapps zip
- wipe
- reboot
for update just flash rom zip from recovery
Google Apps are not included in this ROM. You'll need to find those yourself if you want them.

Frankly speaking, the forums is pretty much jumbled up, and the existing [Guide] Threads are either incomplete (Lacking important steps), or Unclear (Non-Specific steps).
Perhaps someone could do me a favour by using the template that I have below to help me, and possibly others, to install CM 10.2 on our beast of a phone.
Template:
1. Backup TA and DRMkeys and stuff: http://forum-xda-developers-com/backup
2. Root: http://forum-xda-developers-com/root
3. Recovery : http://forum-xda-developers-com/recovery
4: Unlock Bootloader: http://forum-xda-developers-com/ulbl
5: Install FXP's CM 10.2 :http://forum.xda-developers.com/showthread.php?t=2461286
Something like that would suffice I think, as long as no important steps are missing that would cause me to lose stuff unique to my phone, that cannot be recovered if I didn't back it up.
P.S. My version is 14.1.B.2.257
P.P.S. Thank you in advance.
1. Root
2. Backup TA (VERY IMPORTANT)
3. Install Recovery and unlock the bootloader, or the other way around. Both ways work.
4. Install ROM by following the "guide" that you quoted above.

I'm on 14.1.B.2.257, I believe reverting to the previous version causes data to be lost unless you back it up right. *Sighs* How troublesome.

you will have to back up the data anyways. I think unlocking the bootloader does a factory reset, as well one is needed going from stock to CM if i unforget correctly
I am also wondering about this. I'm currently running firmware .257.
I understand that I need to back up the TA partition first (though I'm not exactly sure on what I will loose if I don't). I also understand that to do this I need to root the stock rom. I understand that in order to root, I'll need to first downgrade to an earlier firmware using flashtool. However, after that I'm not so sure what I need to do. As far as I can see, the only method of gaining root currently is to use vRoot, which is currently under investigation for IMEI mining.
How else can I root the device? I was thinking of maybe using the recovery for locked bootloaders here: http://forum.xda-developers.com/showthread.php?t=2426739
Following by flashing SuperSU from recovery as per usual.
Will this work, keeping the TA partition intact so that I can back it up before flashing CM? Assuming so, would I even need to downgrade from the .257 firmware at all?
Thanks,
i have CWM now so can flash custom roms like i did on other phones right?
what does unlocking the bootloader give me? unless i'm wrong and i have to unlock to flash?
all i've done so far is do a backup is all. (did a TA backup a while back though)

OK, so looking into this further, you already need to have root to be able to flash the "CWM for locked bootloader" rocovery. So as far as I can see, the only way to get root in order to back up the TA partition is to give your IMEI to the Chinese via vRoot?
Thank god the stock rom is so good.

You have to unlock the bootloader to flash custom ROMs. You can flash stock ROMs without unlocking it, but you have to unlock it if you want CM, PAC, PA etc.

really, so what would happen if i tried to flash an aosp rom now? would the system partition essentially be read only?
sorry for the Qs but haven't had a locked bootloader since the htc desire (although the s-off for that one was to remap the partitions to allow more room for data) and the reasons for unlocking don't seem to be the same.

Nothing will happen if you try it now. You can easily unlock the bootloader by going to Sony's Dev site, request your key and use Flashtool to unlock it. It takes a couple of minutes once you have Flashtool and the drivers installed. It's also perfectly safe to unlock it and you will lose your warranty. BUT you can easily relock it again if something happens to your ZU and the warrenty will be back.
Remember to backup your TA before you unlock your bootloader. It contains a lot if device info and your unique DRM keys. Unlocking the bootloader will wipe the system partition, but you will still have root, photos, music etc. (But do a backup of those just in case).

i think that's where i got confused with drivers - unlocking.
i have already done a backup of my TA part so that side of it is ok. i'll leave unlocking until there's a rom i want to try. possibly a complete 4.4 or something.

If you've already backed up your TA, it means that you have the drivers installed, so job done All you have to do is to install Flashtool and get your key from Sony (which you will get on your email straight away). Either way, just ask here if/when you want to unlock it so we can guide you through it (it's very easy though).
ran flashtool but gave me driver errors - missing. unable to install the drivers included (i guess due to windows 8 driver signing)
I have a Sony Xperia Tablet Z, 64GB WiFi (SPG312) running stock 4.3, and I can not root this thing. I've tried several different methods to no avail. Does anyone on here know how to root this thing? I'm ultimately trying to install CM11.
Either go back to 4.2, root with Doom's Rootkit, then install a recovery, and install 4.3 already rooted, or unlock your bootloader, install CM kernel, use the recovery built in to install the SuperUser zip, then flash stock kernel again.

So unlock the bootloader? How do I go about that? And after that I can install CM right from there? That sounds like the one thing I haven't tried.
How do I go about doing that?
http://unlockbootloader.sonymobile.com
Follow that link. It's pretty easy. Just make sure you have all the tools in hand. Shouldn't take more than a hour to read everything and do the procedure, if you have everything ready.
It's mentioned there, but remember that it will void your warranty and, with Android 4.3 or lower, on stock ROMs, you will not have Bravia Engine working. Also, in any version, Music and Video Unlimited will not work anymore.
Another big tip: Go to the Xperia Z section (the phone one), and on the sub categories, can enter one called Cross Device Development, or something along those lines, and look for a thread with the name TA backup. If you do the long process, of going back and such, backup your keys. Should come in handy in the future.

u need to download flashtool and find a 4.1.2 rom for your device...
then you can either use framaroot 1.91(gandalf exploit) or use doomlords root setup...
after that you can install phill'z recovery...
http://forum.xda-developers.com/showthread.php?t=928343 this link was very help full for my device sgp311 and i think its almost the same for your device only the rom and the stripped .ftf will be different...
unlocking your boatloader is not really applied to you,you only need it if you want to install custom roms...but before you do search a bit around to find hou you can backup your drm keys aka .ta partition.
Make sure you downgrade to 4.2 and root using http://nut.xperia-files.com/?dlid=V...jb3ZlcnkyLjcuMTIzLUJFVEEuaW5zdGFsbGVyLnppcA== option 3 then backup your TA partition before unlocking your bootloader, or theoretically you'll lose warranty
ok ok ok
So what steps do I take to install CM11?
Which method posted would get me there? You guys are saying a lot of different things here, have me a little confused

Hi all, i have been trying to root and install a custom rom for my Sony Xperia Z2, running stock firmware version 314. Previously i tried using the Dual Recovery that i found on this forum and using that to flash the rom, but it did not boot, so i had to use flashtool to restore my phone to a stock firmware, found on this forum as well. It is also the reason i am running firmware version 314, which i believe is not the latest version available, but i am unable to access OTA sony updates anymore.
I am still able to gain proper root access for my phone (verified using root checker from the play store), but for some reason am unable to flash in a working custom recovery that will help me install CM11 on my phone. I understand now that CM11 requires a custom kernel to operate, but am unable to flash one using Dual Recovery either. I am at a loss as to what to do. Any advice or help is greatly appreciated!
@Taeyeonist9 What did you use to root m8? I think you should read this first m8. You install dual recovery after rooting. If you have any more Q's I'll try and help you. Hope this helps a bit m8:good:
---------- Post added at 04:54 PM ---------- Previous post was at 04:51 PM ----------
Oh, forgot to say that .314 is the latest firmware. May I ask if you have unlocked your bootloader, if you don't have OTA updates You wont get OTA updates if you are on the latest firmware.
Rooting Xperia Z2 Sirius
Hi its the same person here, i've no idea why i have two xda accounts and my desktop's browsers registers taeyeonist9 in chrome, while my laptop's registers taeyeonist, when both chromes are synced to the same google account. Anyhow, thanks for taking the time to look at my issue!
So yea, i realised that 314 is actually the latest version. And ive rooted using the easy root tool in that very link you posted above, i believe. So root access is not the issue. After rooting, I flashed XZ's Dual Recovery ,which includes TWRP, CWM and another third recovery i believe was included in the package. The Dual Recovery as i understand is only meant for devices which run stock kernels, with locked bootloaders. however from my understanding, legal regulations in Singapore, my country of residence, forces telcos to sell their devices without locking their bootloaders. Hence my bootloader is already unlocked and I BELIEVE this is not the issue ( pls correct me if im mistaken).
So the issue comes after i've successfully flashed XZ's Dual Recovery. At first i went on to straightaway flash the corresponding CM11 package for my phone and a copy of Gapps for Kitkat, and my phone soft bricked. Had to use flashtool to restore it with a stock kernel that was obtained from this forum, which resulted in my current condition of the phone - running stock firmware 314, and i was unaware that 314 is actually the latest firmware release, my apologies for that. I've tried flashing a custom kernel package using XZ's Dual Recovery too, DoomKernel v10, DoomLord's Advanced Stock Kernel package that includes CWM in it, neither worked, i ended up in the same softbrick situation. I've tried using fastboot to manually flash the kernels as well, perhaps due to my incompetence, i was unable to get the flash to be successful, it fails no matter what i try. So I'm at a loss now.... my Question is, is there any way i can get CWM onto my Xperia Z2 easily without it softbricking, so that i can then go on to flash CM11 using custom recovery method successfully? It's really frustrating because i know it can be done, i've seen the videos on youtube with ppl using CM11 on their Xperia Z2 devices, and I've tried it out on my spare phone, a SGS3, on which CM11 works wonders, and i really want to experience the magic that is CM11 on my Xperia Z2.
Sorry for my lack of technical knowledge, please go slow on the explanations. And once again, i extend my sincere gratitude to you or any other kind developer here who is willing to shed some light on my problem. i apologise for the wall of text
Thank you!
To clarify, when i say softbrick, i was only able to get the device in fastboot mode, and through flashtool, flash a copy of stock kernel obtained from another xda thread to restore it to factory condition. Other than this restoration method, my phone was essentially a brick. Nevrvewrecking:/ Appreciate the advice!

Hi!
May I include my understanding of the issue.
I will get in the same situation in a view days when my Z2 will arrive.
At first, you have already root rights (rooted device) this doeasnt meen that you can flash what ever you want. It only means that you have more access right to your system than normal.
Bootloaders are locked by default but in some special cases it is not allowed to unlock it. (check service menu to get the info if unlockable or not)
If you want to flash roms with locked bootloader be shore to use roms with are able to be flashed with locked bootloader (LB), because the didn't change your kernel.
If you want to flash roms with a different kernel than stock you have to unlock you bootloader first, than you can flash almost every rom also the one statet (UB).
BTW: I thougt CyanogenMod uses there own kernel so its necessarry to unlock your bootloader if you want to flash CM.
However if you need to unlock the bootloader at first get root rights and backup your DRM keys because if they are lost you are unable to restore them any more, and they are necessarry if you will recover your phone to stock.
Hi all,
Firstly sorry, you must get this all the time and be really bored of helping but i would be so grateful if anyone out there can point me in the right direction.
Firstly my phone details;
Model - Xperia Z2 D6503
Firmware - 1278-4770_23.0.1.a.3.9
Network - EE
Rooting status;
Bootloader unlock allowed: No
I want to root my phone but after reading what seems like thousands of web pages im more than a little confused. Does anyone out there have a step by step guide for beginners?
I want to use cwm recovery but don't understand how to get that on the phone as most guides say use it to back up before doing anything else but it isn't there to start with!
Also will installing cwm wipe my phone and sd card?
Any help would be much appreciated and many thanks in advance.
You can only install nuts dual recovery on a locked bootloader, proper recovery is included in the kernel and the kernel can only be changed on an unlocked bootloader, there was a a guide to rooting in one of the forums and I assume towel root will work, just search the z2 forum you'll find it

Is nuts recovery better or worse than cwm? Also i thought that towel root would not work with 4.4.4 at present?
Does the locked bootloader mean i cannot do certain things even after rooting my phone like install custom roms and kernals?
Many thanks

1) You cannot root the firmware you are on with a one click tool (like towelroot) at present. You have to downgrade to a lower firmware like 17.1.2.A.0.314 first and then root that, install a custom recovery and install a pre-rooted firmware package.
2) Your bootloader is hard locked by EE, this means that you will never be able to unlock it and install custom kernels nor custom ROM's what require custom kernels.
3) It is more than recommended to install [NUT]'s dual recovery, this installs PhilZ recovery (a more advanced CWM in my opinion), TWRP and CWM (to use CWM you have to install dual recovery manager from google play AFTER installing the dual recovery).
4) Now to downgrading, you will need to download a program called flashtool (this can be found in the Sony Cross Device development section) and the .314 ftf file (not .tft, ,ttf, .fft or any other variation people mis-spell it as). You will then need to install the drivers for your phone (these can be found in the flashtool drivers folder in the location you installed it, also if you have Windows 8 or 8.1 check my signature on how to disable driver enforcement before attempting to install the drivers.) There are plenty of guides on how to downgrade, there is even one in the firmware collection thread what can be found in the Z2 general section. Side note, when downgrading you will HAVE to wipe data and the cache (this can be selected when you are selecting the firmware to flash) or else you will end up with a phone what is in a bootloop.
5) After downgrading you will need to root, the easiest and simplest way to root would to be use the easy root toolkit (this can be found in the Sony Cross Device development section).
6) After rooting you will have to install [NUT]'s dual recovery (Sony Cross Device development section, you will need the installer file and not the flashable file).
7) After installing dual recovery you will need to flash a pre-rooted zip file of the latest update (Z2 Android Development section, I think the one by @niaboc79 is the best one to use). Alternatively you could install a custom ROM what is based on stock, it will tell you if it is.
If you need any more help, just tag me in the post (by using the @ symbol and then my user name) or PM me. Also, @Envious_Data is a great help in this device forum, helped me when I had a few queries about the phone before I got it and I have seen them help a load of people in the Q&A section.
@gamer649 Thank you for taking the time to help me, that has explained everything perfectly. I do however have a couple more questions i think you'll know about....
1 - Is there a back up app available that will do a similar back up to that of "apple". I mean reinstall all the apps i currently have and keep the home screen layouts and all data etc?
2 - In the link to the firmware downloads you gave me there is only 2 UK .314 ones and none of them are EE, shiuld i just use the unbranded one and what are the differences?
3 - The main reason i started looking into rooting was that i heard about a tweak to increase the volume of the z2 notifications by forcing it to use both speakers. Have you had any expierience with it and what other tweaks would you recomend?
Thanks again and i look forward to hearing from you again

1) You could try using the stock back up and restore app for that. Also, if you have your data backed up with your Google account it will start to reinstall all your apps along with their data once you sign in once you downgrade. @Envious_Data any other suggestions for a non-rooted device?
2) I always go for unbranded software, the reason being that there are no carrier apps nor carrier boot logos installed into the ROM and it is how Sony intended it to be. Apart from that I don't think there are any differences.
3) I don't usually have my phone on sound mode, it is either silent or vibrate so I can't help you with that one. You could take a look in the Z2 android development section to see what mods are available, some ROM's may also include this feature.

1. You can use root to copy all of your apps from /data/app and you can use flashtool to bulk install all of them
2. Branded firmwares occasionaly have some small changes for better reception on the selcted network but with 314 this doesnt actualy matter
3. Have a look around for some mods, and see if they are compatible with your current firmware version

I've trird installing the drivers via the \FlashTool\Drivers directory.......but always get the following message "DPInst.exe doe not execute on your current operating system" - I'm running Windows 7 Ultimate 64bit
Any and all help would be greatly appreciated as I'm desperate to install CM KK 4.4.4 and get rid of the Sony stuff.
Thanks in advance

don't use flashtool for unblocking BL (cause you can use instruction from Sony's site), or install drivers properly: look for dpinst.exe in your temp folder and set compability mode with WinVista in it's properties and it will install properly.

Thanks for your reply/suggestion. Unfortunately I do not have the "set compatibility" option in DPInst.exe properties. I have found 2 x dpinst.exe and 2 x dpinst64.exe files on my system.
I've tried using the Sony site instructions but
1. When i attch the tablet to my laptop in Fastboot mode (Vol up), and type "fastboot devices" at the cmd prompt, i dont get any indication that my tablet has been/is recognised (see scrrenshot 1)
2. When I run the unlock command using the unlock code obtained from Sony, command line sticks at "waiting for device" (screenshot 2)
i'm at a loss as to whats wrong \ what Im doing wrong
All / any suggestions welcomed as am desperate to install CM11/12.
Thanks in advance

Check that your tablet's fastboot drivers are installed correctly in device manager on windows. I haven't done this on the tablet z (yet), but if you do not have the drivers installed on a nexus you wont see any device in the fastboot devices option.
So i would suggest you download the correct drivers (preferably from sony, but google drivers might also work), and check that the device manager dont have any unknown devices (tablet z) and if you do not try reinstalling the driver by uninstalling the current one and getting the correct one from sony or the google drivers.

Thanks - you were right, it was drivers. Finally managed (I think) to unlock bootloader.........but am now stuck in a bootloop .
Any suggestions welcomesed
Use flashtool and simply flash any stock version on top.
Alternatively, you can use some non stock ROM, but for that your first need to install the custom recovery via fastboot.

If your stuck in a bootloop i would suggest trying and flash recovery through flashtools and see if you can clear dalvik cache in the custom recovery.
it might help.
but otherwise do as the others say and flash a custom rom (CM preferably).

hanks for you help.
I have rooted and unlocked the boot loader of my SGP321 (WiFi/LTE).
But every time I install CM12 (flashed zip via TWRP), I lose Root......and as far as I can see, there's no way back from that, bar a complete re-install of stock (KK444)
Really frustrated as have wanted to flash CM and get rid of the Sonly bloatware (example: of 2gb internal memory, the stock firmware leaves only c.500mb free....thats just plain ridiculous. Compared to CM12 which leaves 1.7 GIGS free.
any suggestions.......?

CM12 should have root built in, check developer options for it on your device.
If not then just flash SuperSU.zip from chainfire (i prefer chainfire's version of super user).
Chainfire's SuperSU is here: http://forum.xda-developers.com/showthread.php?t=1538053
please note that i have not tested this on a Tab Z but it should work.

Thanks for the speedy reply. Really appreciated. I've gone intp developer options.....but what am i looking for?
[EDIT] In Developer Options, and under "Root Access" it says "Disabled"
[EDIT 2] Downloaded a RootChecker and it tells me I'm not rooted
I'm totally frustrated.....have been trying to install CM12 for the last 6 hours!!!!
NUT (duallockedrecovery) has done a fantastic job developing the xzdr.........but i have to say that, in common with a lot of devs.... not very good at writing nstructions.
I'm an IT manager and often train staff in systems etc, including writing user guides. When writing guides/instructions, I ALWAYS assume that the end user KNOWS NOTHING......and so the guides/etc are very detailed. Yes, it takes a while to write them, but feedback shows its the right track to take.
Almost all the articles on flashing CM12/using Fastboot etc lack small, but important, details......!!! I'm still not really sure if i should be using TabZ-lockeddualrecovery or XZ-lockeddualrecovery..........!!!!!!
i've got as far as I have by pulling together numerous XDA posts in order to get a (full'ish) picture of what to do. Devs, pls make your instructions clearer for people who aren't devs. Rant over
My current position is that my Xperia Tablet Z is
1. On KitKat 444 (Firmware ver. 283)
2. Rooted
3. Bootloader unlocked
4. SuperSU & SuperSu Pro installed
How do i get from this position to a successful CM12 install?
I have CM12 Nightly (7th May), GApps 5.0x Minimal ready and waiting....
I'm not a stupid person, but trying to do this has made me feel like a complete idiot.....help!!!

Yea i know what you mean by guides not being written to include alot of details and missing out on small stuff that might be important, but anyway.
In the Developer Options there should be a box called Root Access, and it should be defaulted to Disabled ones you have installed CM12 for the first time, its just a matter of enabling this.
Im guessing you already know how to enable Developer Options, but if you dont here is how:
Go to About Device (or Phone/Tablet) and click on Build number a bunch of times (i think its 5-6 times), and the developer options should be visible in the settings.
If that dosent work you might want to try and flash the SuperSU binary through recovery, the zip to use is the one found in chainfires xda-thread here: http://forum.xda-developers.com/showthread.php?t=1538053
But here is the direct link for the zip https://download.chainfire.eu/696/SuperSU/UPDATE-SuperSU-v2.46.zip
Just put that on your device internal memory (or SD-Card) and flash it in your recovery of choice, it should work in CWM, TWRP and Odin (but you dont have a samsung so the last one dosent matter).
This should install the SuperSU app, and its basic su binary onto your CM12 rom.
In both cases i would recommend you install root checker (https://play.google.com/store/apps/details?id=com.joeykrim.rootcheck) and see if root is available to you.
Also to note is that the Root Access option built into CM12 isnt that customizable and i would still recomend you install SuperSU, but if the Root Access option is working you can just download the SuperSU application from the play store and let it install SU binary and then you can disable CM12's built in root option ones you make sure the SuperSU was installed correctly.
Thanks so much for your help/patience......but i'm afraid im giving up (for now).
Will try again in a few days......so its back to rooted stock 444
By the way, why have CM decided to go with their own (as good as useless) recovery????
I forgot to say that you've helped fill in a few more gaps for me in respect of this i.e. flashing SU; changing Root Access in Dev. Options etc.
These are the things that all the articles ive read FAILED to mention.
Thanks so much

No problem, if you have any other questions just tell me and i might be able to help you
I have also been in the dark about this stuff before, and im still not used to other manufacturers style of rooting and unlocking the bootloader (sony is the next best after Nexus) since samsung and the others usually you have a harder time unlocking and rooting.
But good luck if you try it again :victory:
