lollipop 23.1.A.1.28 Bootloader, Root, Recovery help - Xperia Z2 Q&A, Help & Troubleshooting

Hi,
I recently recieved a z2 d6503 and was already on the said latest firmware.
Ive noticed i needto downgrade to kitkat and a rootable firmware
I downgraded to 17.1.A.2.55 and tried to flash recovery using this guide http://techglen.com/2014/04/05/inst...6543-17-1-a-2-55-17-1-a-2-36-firmware-how-to/
It seems to flash the boot image okay but i cannot enter recovery as if it didnt actually install.
And i cant unlock my bootloader as the http://developer.sonymobile.com/unlockbootloader/ website seems to be playing up
Really frustrated, every guide ive followed wont install root or recovery even on the right firmwares
My flashtool, adb and fastboot are all connecting fine
any help is much appreciated

Welcome to the club man, hope you'll enjoy the ride.
Now to business, to root your D6503 you have 2 options :
- downgrade and follow our own awesome XDA-TV guide : http://www.xda-developers.com/how-to-root-the-sony-xperia-z2-xda-developer-tv/ (I used this one when I got my phone on KK, worked like a charm)
- remain on LP and root using this thread : http://forum.xda-developers.com/xperia-z2/general/root-t3108230
unlocking the bootloader is needed if you want to use a cusom kernel, and if you decide to do so, make sure you backup your TA partition first, look here : http://forum.xda-developers.com/showthread.php?t=2449244 or http://forum.xda-developers.com/showthread.php?t=2292598
I suggest holding off on the bootloader unlocking, play around with the device a bit and see how it feels first, then you can decide.

Thanks so much for the very detailed reply. I will give it a go tomorrow

[Q] Installing CM-10.2 Android-4.3

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.
cheers LM

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)

Complete noob and new to Androids!

Hey peeps,
Am totally new to android as I have only just binned my iphone contact and got a Ultra, the issue am having, I am reading and reading and getting nowhere fast
I would like to root my phone but I seem to be getting stuck in an endless loop which I don't know how to break!
Phone is brand new, no contacts, nothing, I just want to do the following, which I would have thought would be in this order,
Backup the TA (As I have read and read that this will save the DRM keys, which once lost are gone)
Now, I read to backup the TA, I need to root, to root I need to unlock bootloader, to unlockboot loader you have to root all of which then I read is warnings that you can lose the DRM's
Arrrghhhh
I have the flashtool installed
Am on .757
My bootloader is locked but unless the .757 update changed it I was able to unlock it but everything I have tried and read doesn't work
I have my unlock key as well, and I have vague idea's what I want to do but there are so many threads and everything seems to loop back to to root, you need unlock, to unlock you need root to flash you need root lol am going crazy.
Am not sure why am struggling so much with following the guides but I guess it's cause I have zero experience with doing this.
any help would be greatly appreciated
Yeah, I'm not surprised by this at all; and welcome! You have to downgrade to 532 using Flashtool, then root, and then backup the TA partition. You're free to upgrade to 757 again after that, unlock your bootloader and root 757.
Sent from my Z Ultra
Thanks for that info mate, so far that's made more sense than searching all of these posts
Am thinking about two steps in this guide to downgrade
http://forum.xda-developers.com/showthread.php?t=2593918
First one seems very simple, but second one seems to flash them back to solid stock from the look of it.
Once downgraded,
I thought you require bootloader unlocked before you can root, and from what I read you need root to unlock/backup, or have I missed something?
(hopefully will be back to 532 shortly after files finish downloading.

Hey mate, yesterday i had successfully root my XZU with locked bootloader and no backup TA or else, because I'm not yet decided to unlock.
Currently your device is locked or unlocked bootloader?.
Perhaps i could help you.
Currently mines locked.

Just do as has been said a thousand times...
Downgrade to .532 - see my downgrade thread
Root using either [NUT]'s dual recovery or bin4ries tool - see thread in step above or LordManhattans guide
Backup the TA - see LordManhattons guide
Upgrade to latest FTF
Unlock bootloader
Root using jackies099's kernel
...
After hours of reading and searching around and trying to follow what LordManhattan said.
I have the phone down to 523.
I now have the bootloader unlocked
Just not sure on the rooting of the phone..
With Flashtool can I simple press the Lock key and root it that way? I don't know the difference between Superuser or SuperSU
Or do I have to do it another way?
I have looked at a number of rooting options and am unsure what to do, one way the links on the guide didn't work others are little confusing!

The order you have done it in is just wrong, so wrong... But what's done is done
Now that the bootloader is unlocked just flash a 757 FTF and install jackie099's kernel http://forum.xda-developers.com/showthread.php?t=2714511 and then flash SuperSu from recovery
Did you just skip backing up TA partition? Because if you did, that just defeats the purpose of downgrading

Morning peeps,
No atm I stopped at unlocking the bootloader after the downgrade, I have tried to run the Backup-TA-9.10 app but it fails on detecting Root cause obviously mines not rooted.
So regarding backup am not sure what am supposed to do, as all threads seem to point to that you require root to backup o.0
blueether I have read so many threads my eyes feel like they are going to bleed, like my original post stated, it seems to be a loop I was getting stuck in.
I cant backup without root from all the threads comments
I cant root without backup for safety and bootloader unlocked, and to unlock bootloader it seemed I had to be a specific version namely 532 to unlock.
So I have got somewhere, instead of pulling my hair out going no where
I hope the way I have moved forward doesn't or hasn't caused any possible lose of keys etc, so the question is, how do I backup before trying the next step of root?

Hey dude, what's going on? .. have you successfully root yet?
Which step is you dont understand to ROOT? .
Done the downgrade!
2.Root using either [NUT]'s dual recovery or bin4ries tool - see thread in step above or LordManhattans guide
Its the above, gone to Bin4ries post, the links don't seem to download for me? so cant get the tool to do the root
3.Backup the TA - see LordManhattons guide - should be able to do that, its working to the point of seeing it's not rooted, so not worried about that part!
4.Upgrade to latest FTF
5.Unlock bootloader - Already done by mistake thinking it was done easiler :S
6.Root using jackies099's kernel
7....
The thing I have noticed as well atm which am slightly worried about, is my sim card says invalid atm, hoping that changes when it's all finished

Lol, you shouldn't unlock bootloader =.=" if you only required ROOT =.=".
if you worried, flash stock rom and redo to root?
Well am confused and lost atm.
Point 2 and Point 6 to me, are they not the same thing?
Trying to carry out Point 2, I cant get any of the software it seems as I cant get the links to work
So atm I have a phone working but telling me my sim is "invalid card - no service" currently
Any help for links to the Nuts, or Binary software would be grateful

the sim/imei problem shouldn't have happened if you followed my guide, but dont worry, it will come back after step 4

Step 2 is only so we can get a backup of the TA so that it is safe to unlock the bootloader
Step 4 when you update to the latest FTF you will lose root
Step 5 will allow you to get root any time you want without having to do the downgrade dance
Step 6 is needed because the stock kernel wont keep write access to the system. This step also re-installs recovery so that you can flash the superSU update binary
Hi Blue,
Feel like am getting my self further and further into the **** with this
I was able to find bin4ries tool after searching on the net for awhile, and used that as advised, which has worked and didn't seem to be a problem, the SU appeared etc.
I then did the Backup which again has gone fine.
I updated what I thought was the latest TFT C6833_14.1.b.2.257_euro-lte.ftf from one of the links but looking at the phones version am still showing 532
That's the stage am at with still the sim/imei issue
I have downloaded the link you have provided for the lockeddualrecovery looking at it, I get options to
1. installation on ROM rooted with SuperSU
2. "" "" " with SUperUser
3. installation on unrooted ROM
4. exit
at this stage am not sure what to do, as I thought getting all the other steps completed now would have solved this.
Think am starting to regretting trying this and feeling like a total tool!

[Q] How the **** do you root this thing?

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

[Q] Lost for root my Z2

Hello, I had my Z2 there some day and I want to :
Root
Unlock Bootloader and do a Backup "TA"
But unfortunately I understand anything about procedure and what to follow.
I had a HTC one X who was also root (Fairly easy to do). And afraid to make a false manipulation, I prefer to ask you directly.
Even with the tutorial XDA I understand nothing
Here is all the info:
Build Number: 17.1.2.A.0.314
Android version: 4.4.2
Model Number: D6503
Color: Black
What program should I use?
I had heard of "Towelroot" but apparently it would be outdated.
There are also "rootkitXperia" but when I open it strikes me as' Ads is not recognized as an intern command"
"FlashBoot" Is it still relevant or is overcome?
I activate the developper Mode and the USB Debugging
Thank you for your help :good:
Edit: The phone is root, but when I try to follow the 3 steps of the backup TA that does not seem to work because I find no backup.

Hello, I had my Z2 there some day and I want to :
Root
Unlock Bootloader and do a Backup "TA"
But unfortunately I understand anything about procedure and what to follow.
I had a HTC one X who was also root (Fairly easy to do). And afraid to make a false manipulation, I prefer to ask you directly.
Even with the tutorial XDA I understand nothing
Here is all the info:
Build Number: 17.1.2.A.0.314
Android version: 4.4.2
Model Number: D6503
Color: Black
What program should I use?
I had heard of "Towelroot" but apparently it would be outdated.
There are also "rootkitXperia" but when I open it strikes me as' Ads is not recognized as an intern command"
"FlashBoot" Is it still relevant or is overcome?
I activate the developper Mode and the USB Debugging
Thank you for your help :good:

Are you using the toolkit to back up your TA partition? The toolkit should be found on the cross development section. If you can use a previous version such as v9 or something, all you need to do is go to towelroot website and download the apk, put that new apk into the 'files' folder of the toolkit and then run the install.bat file and follow the instructions.

Hello,
Thank your for your replay.
I just want to save the TA partition, Bootloader and then have a Custom Rom (Is the fact of changing rom allows to have a phone to unlock operator?)
toolkit is used to be the only root ?
@Steinshy Ok m8, for TA use this (assuming you have windows).
For root use this (I used v11 to root .314 firmware with a locked bootloader). Also read this It has lots of info and usefull links. If you want to flash a custom rom you'll need to flash this (assuming you have a locked bootloader). If your operator has locked your phone i.e. Bootloader unlock allowed: No it doesn't matter cause you can still root. You just can't flash custom kernels or roms that require a custom kernel. I hope this helps you a bit m8. If you have any more questions don't hesitate to ask. Good luck m8:highfive:

Rooting Xperia Z2 (Sirius) and flashing Custom Rom

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:

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.
