[Q] Xperia Z2 urgent flash help needed - Xperia Z2 Q&A, Help & Troubleshooting

Hello Fellows!
So after having my Xperia for 1 year I got kinda bored of it's design and wanted to flash and customize it.
I like customizing a lot and I never had problems ever since I flashed my first PlayStation Device.
But now I am hardly irritated about my smartphone. There is a great tutorial here, which would be amazingly helpful to me, if I knew more about the recent Android versions and the customization tool I want to use (since that's all I really want).
To state my problems accurately, I was looking for complete customization of the Android UI and came across here. Now, an app called Themer has been recommended for such a thing, but it requires flashing my phone in a way.
The first thing that irritated me, is the fact it's engine is taken from T-Mobile software (My Xperia is one, at least google states it downloading something from the Play Store Website ("Telekom Sony D6503"). I don't know if there is a connection, but my main problem is the flashing now. Recently the Lollipop Update came out, but I updated my phone just 2 days ago getting the 4.4.4 rev. (23.0.1.A.0.167). Also I don't really understand the CM10/11 thing or which I should apply in order to not mess up my phone. EDIT: Just reminded myself of the "Bootloader", I need to figure out if it's locked or unlocked...
Specifically I want to apply this theme:
http://forum.xda-developers.com/showthread.php?t=2631573
Don't judge it please, I kinda like the minimalistic style.
What can I do to apply this theme correctly and which ROM would be useful?
Can I apply this theme whatsoever?
Thank you for your answers!
EDIT: I've been trying to ROOT my phone with phone with the instructions. I tried to to do it without unlocking the bootloader (since this is a valid option) and something happened, but at the same time didn't.
I tried to install the recovery and root it to gain superuser, but it didn't really work out, except my phone having a new Bootscreen ("powered by Android" after the Sony Xperia start up).
Where did I go wrong? My PC loads drivers for S1 /SOMC Flash when starting up my phone with VOL-/PowerButton, but I can't get into the phone's recovery mode... (I think it was TWRP)
I just don't understand the world anymore .__.

OK, hi m8, Xperias with Locked Bootloader (LB) don't use Theme Chooser. You can get it in Cyanogen Mod (CM) and for CM you need to unlock your Bootloader. As for rooting 4.4.4, you need to read this. Basically, you need to downgrade, root then flash a pre- rooted zip. Hope this helps m8. Good luck :good:

[Q] First time Sony user needs help

Hello guys,
Firstly I would like to inform you that my device is coming in 2 days from now and I would like to take it out of the box and root ASAP, since i cannot live without root since my first galaxy S.
Not knowing Sony's devices I have been reeding quite alot, but all I got was confused.
I've read all sorts of rooting without and with locked bootloader. The bootloader concept is not new to me, since i've had a HTC One m7 5 months ago, so that part I got.
What I do not realize is how come you lose certain rights or apps, or whatever when you unlock the bootloader, but i know you can backup the "TA partition", for whatever that is worth. But, that if i onlyroot i do not need flashing it and if i unlock the bootloader i cannot flash it or it will brick it, meaning i can only really use it on bootloader re-lock, which, again, is a familiar concept to me.
Now, for what matters, and i am sorry for probably repeating the subject, I would like to know the following thigs, if you are ever so kind:
- what is the difference between the FW .55/.69 to the 402 and is it worth not rooting (since i will not be unlocking my BL)?
- how do I get the drivers and what do i need to root it (i prefer the easiest, safest and fastest methodthat is motly or all automatic)?
- can I install any kind of recovery (preferably TWRP, since i used it i've deemed cwm dead) whilst BL locked?
- can i install custom roms on a locked bootloader if the rom does NOT come with kernel changes?
I thank you again for your kindness and patience for my questions, since I know well how boring it can get repeating yourself on Q&A
Hi.
I just got my Xperia Z2 the day before yesterday, and it hasn't been even 15 hours since I rooted my device. And it is my first sony too. I came from Galaxy note ( original) and the rooting process was very different. So I don't know many of your questions and the ones I do now, I'm not sure about.
First I think you can root without unlocking your bootloader and then backup your TA and then unlock and upgrade too a custom build of 402. If your device is on 55/69 you can use Z2 exploit ( I think it was by doomlord.) which root and make a backup of TA. I gained root by this method. then if you ever wanted your bootloader too be like day 1, you can with your TA backup.
as for the drivers, I found a package containing every driver I needed. I don't remember the domain I download it from, but the file name is Flashtool-drivers-1.5-20140318 . I think you can search and find it.

[Q] Verizon Sony Xperia Z2 Tablet (SGP561)

Recently picked it up, an SGP561. I have some questions and I'd love all of the help I can get.
1. How to install a custom ROM on it (just in case). If I can't get the updated Sony firmware, I might as well jump to an Android 5 ROM once they're stable.
2. How to update the stock firmware. Everytime I go to the System Update thing it says there was an "Error during DM Session"? I'd really like to update to 4.4.4 stock to get some of those nifty Sony features.
3. Anyway to get the damn thing to shut up when I turn it on? I'm not using it on a data network, just WiFi, but I like having the option, but everytime I start the damn thing up (from being completely off) it makes a calling new and does through this automated annoying thing asking me about purchasing a calling pin, and it does that for about 7 minutes and makes me about go insane.
Anyway, thanks guys. Boxes of donuts to all of those who answer.
(Already rooted the thing)
Hi Grayson,
1. Currently, there is no way to unlock the SGP561's bootloader. So basicly, you can't install any custom rom that is not based on stock rom (or use custom kernel).
2. Mine gets the same error. But you can download the latest ftf file for SGP561 and flash it manually using flashtool (sadly, the latest version is still at 4.4.2).
3. I face the similar situation, the tablet automatically dial some number to activate it when it boots up. All I did was just simply removing the Verizon SIM card (I don't use data anyway).
1. Well ****. That's actually very concerning... This tablet probably won't ever see Android 5.0 then... unless some genius out there cracks this bootloader deal. I know how Verizon is with things.. or I'll see an outdated version of Android a year after all other variants get it. Are there any ROM options?
2. How do you go about doing that? Pardon the noobishness.
3. Thanks! I didn't even know that there was a SIM card in there in the first place. That was a great help. Same here though.

1. Yeah, I know how that feels. You bought one of the top high-end tablet and then figured out that it has the outdated software and there is no way to update. I've been looking for other solutions for months but still found nothing.
2. The latest version is now 17.1.D.0.437. You can check in your tablet settings to know whether yours is on the latest or not. If it's not the following links may help.
Here is the instruction how to use flashtool (just in case you have no idea about it): http://forum.xda-developers.com/showthread.php?t=2054486
And here is the link for the latest ftf file for SGP561: https://mega.co.nz/#!VZYHRAKT!wky8U_6G9aB4XctdfKMIaJQZtdlnWTtNv0pNLlgh0AM (I got from this thread http://forum.xda-developers.com/xperia-z2-tablet/help/flashed-wrong-boot-bricked-t2839828)
Well this all sucks a lot. Why can't they just leave the bootloader unlocked... hopefully this tablet wasn't just a massive waste of money.

I got mine two days ago, also have the Galaxy Note Pro 12.2, which I use at the office, but I needed something that had a smaller screen, was light, and had 4G, and the Sony ticked the right boxes. I WISH I could use Xposed but it can't write to /System. I have it rooted and got rid of some bloat, and the only thing I really want now is for Xposed to work.
You guys don't think Verizon will update this tablet to Lollipop?
Hi I just updated my tablet to lollipop and I'm having problems with it. I tried downloading the ftf for kitkat above but he kinks we're dead. Do you still have it by chance?
Still no options to unlock the Verizon's SGP561 ?

Just want root access; happy with stock ROM. Possible?

ok so please be gentle here, coming back here after 7 years, from old Windows Mobile days!
I am a newbie to Android and want to root my Z5 compact. The only reason I want to root it is to enable some apps like Greenify and GSam battery monitor to work with all their features enabled. I do not want to flash a new ROM. I am happy with Sony's stock ROM.
Is it possible to get root access without installing / flashing a new ROM?
I have searched the internet but people talk about flashing every time I read about rooting. Then I also saw this thread: http://forum.xda-developers.com/xperia-z5/development/root-automatic-repack-stock-kernel-dm-t3301605
Lots of geeky stuff there which is fine, but again, it seems to talk about flashing the ROM, which I really do not want to do or do not see the need (yet).
Unlock boot loader:
I see that Sony lets me unlock the boot loader from their dev site. I am willing to unlock the boot loader. (Not sure if I want to do that first. Maybe unlocking BL is all I need?)

The only reason to use that guide is to backup ta keys for whatever reason you'd want to do that.
If you're after root on stock ROM the single easiest way is to unlock bootloader, flash twrp 3.0.2, flash xpower 3.0, and that's it. Solid marshmallow with root goodies. Xpower has everything and is deodexed and ready for xposed framework.
just a little more clarification please?

Ok thanks.....that sounds straight forward.....but isn't TWRP a ROM? (sorry, the moment I hear flashing...I think ROM)
And I am looking up xpower...not sure what that is (yet) and why do I need it
I do want xposed framework though.
I wish there was a simple straightforward answer

Twrp is your recovery,you flash through fastboot, xpower 3.0 is the ROM, just a pre-modded stock ROM with options of xperia x addons. Use lite and stock kernel for xpower and you'll be set.
still a little confused

Ok thanks! So my understanding (so far) is :
We "must" flash a ROM in order to root a phone. Did I get that correct?
Since I said I like the stock Sony ROM, you recommended the xpower 3.0 ROM.........but the point is.....I still have to flash ROM.
A little confused here...
I am a systems engineer (my day job). In Linux or Windows OS, if we want root access (to run some software or a low level command, like partitioning a disk etc), we either run SU command and put root's password OR right click and run as administrator......
We never have to install a brand new Operating System to get root access.
Just a total newbie question.....Why do we have do install a whole new OS (flash new ROM) on our Android phones to get root access?

Android is Linux, to gain root in the ROM you have on your phone currently all you need is an unlocked bootloader to run SU, but then you'll be left with a phone that still needs a customized kernel to keep root and a DRM fix for the camera. Xpower 3.0 is that package.
You could really benefit from reading more. Google up on dm-verity and Sony Ric, and fastboot/adb for a little better understanding of what you're getting into without a pre compiled ROM. Messing around with any Android you'll have the majority of the same steps, unlock bootloader with fastboot, flash Supersu, customized kernel.. Etc
Why use a stable compiled ROM?
Let me list down and explain to you why it's best to use a stable compiled ROM. But first you need to understand these few things before you decide to unlock your bootloader and root.
Before Sony Z models kicked in, every rooted Sony device are still able to retain all the features that came together with the phone before it was rooted. When Sony introduce the first Z model, they start to create these things called DRM keys. DRM keys are unique algorithm (i guess i should put it that way) which is attached to every phone the same way an IMEI number is attached to every phone. In short, my DRM keys cannot be used on your phone and vice versa.
DRM key: It's a unique algorithm that holds all the unique features that an unrooted Sony phone boast such as camera quality, X-reality, High Res Audio etc etc.
The moment you unlock your bootloader, that's the moment your DRM keys will be lost. But don't panic, the wonderful devs on XDA have prepared a tool to backup your TA partition (a partition that contains your DRM key) for your own convenience if you want to relock your bootloader.
Then recently Sony/Android come up with new features called Sony RIC and dm-verity. (You may Google what these are all about but to my understanding it is placing limitations to people who root their phones to meddle around with the system settings of thier phone)
With all these "hurdles", it have taken some time for devs here to find a work around and like every fairytale ending, they manage to find a way.
Now you're wondering if you can actually root without flashing another rom. Good news for you: you can! There's a guide that will teach you how to actually root and apply the work around after unlocking your bootloader and rooting.
.. But ask yourself what's the point of going through the hassle of rooting and your phone is not tweaked for performance or for theming purposes?
That's when people flash roms and in Z5 compact's case, XPower is the best rom there is. It gives you all the performance tweak you need to make your phone lag free, it has a lite version that removes all the unnecessary system apps you can't delete without root, it gives you an option to add themes and framework from Xperia X with all those work around in place.
For your second question: why is there a need to install TWRP?
TWRP is a recovery tool which is a need for all rooted phone. It's also a tool for you to backup and restore your current rom so that you can rollback to the last working configuration if your phone went into a bootloop etc. Plus i believe all these guides require you to actually use TWRP to flash the SuperSU to successfully root your phone.
I hope this explains your doubts.
Thanks a lot but...
firdyRAY, thanks a lot for the comprehensive reply to my questions. And yes, it has shed a LOT of light on my doubts.
I googled Sony RIC and dm-verity:
I could not get find much on ric
Dm-verity seems to me a way to check if the boot image has been modified from the last boot, and if it has, stop from booting. Sounds like a good idea until we understand that to flash a ROM dm-verity needs to be bypassed/turned off.
So to compile what I have understood so far:
By unlocking bootloader, you lose DRM keys. There is a way to backup DRM keys which are in the TA partition, but this is to be done BEFORE you unlock bootloader. Good that I have not done anything to my X5c yet.
The next steps for me would be to look into XPower 3 ROM…which I did and here is what I found out:
http://forum.xda-developers.com/z5-compact/development/rom-xpower-v1-0-aroma-debloat-custom-t3371100
First, what's up with the scary looking warning in RED right at the top of the first thread. I did read the OP and the second post, I did not see anything in there which IF I missed will cause my phone to explode! That is probably posted to make noobs read all instructions, right?
Second, I do not see any step in there to backup the DRM / TA partition. I guess the dev is assuming the phone already has lost the DRM, right? So I gotta find instructions on how to backup DRM / TA
Then I searched for problems in this ROM and seems to me that the fingerprint sensor is reported by many to be not working and/or buggy. I rely on the fingerprint sensor day and night. I have many apps which rely on that, like lastpass. That would be a major deal breaker for me.
So going back to stock ROM option…I remember you said "There's a guide that will teach you how to actually root and apply the work around after unlocking your bootloader and rooting."
Could you please post a link to that?
Thanks again!
I think this is a pretty great thread rajdude. It's getting people to spell out a lot of information to noobs like us that it seems most posters have taken for granted over time.
I'm a complete novice at all of this. Sort of gleaning information as I go along, but I used this guide: http://twigstechtips.blogspot.hk/2016/04/sony-z5-compact-root-without-losing-ta.html?m=0
Along with this guide: http://forum.xda-developers.com/xperia-z5/general/guide-rooting-unlocking-bootloader-t3354307
The first guide is pretty basic step-by-step instructions. It unfortunately occasionally kind of skips over a couple very small things (that will be clear as you go along), or occasionally words things in such a way that might not be completely intuitive, but maybe that's cause I need things explained to me like I'm five sometimes. Any time I might have had a question about something in the the first guide, I went to the other and found the answer. It didn't take me long to get the gist of the whole thing though, and overall, it wasn't as scary as I thought it was going to be. It'd be fantastic if someone created a video walkthrough, but so far as I know, no one has done that yet.
The guide will help you back up your TA Partition where your DRM keys are stored, unlock your bootloader, root your device, and then restore your DRM keys. In order to do this you need to downgrade to Lollipop (if you're not already on it), and then upgrade back up to Marshmallow. It will also install TWRP (which I had no clue was installed until I went into "recovery mode" by pressing UP when I saw the LED flash yellow during boot). There may be an easier way to go about this whole process, but this is the process I used.
Before jumping into anything, I'd hold off until you heard more from firdyRAY or someone more experienced. They may look at the guide I linked and be horrified.
And yeah, I haven't installed xpower yet for the same reasons you haven't. Sounds like there's even an xpower 4.0 that was released recently, but still seems kinda buggy. Being rooted with stock I've been able to give Greenify access to root. Install Adaway (which was worth getting root to begin with). Install sound/music mods like DiVA-X, Viper4Android and Dolby Atmos. Install Titanium Backup. And make a few other minor tweaks (that I've since reversed). I still don't know much about custom ROMs and all that jazz, so I'm holding off until I get more understanding. I'd love to install the xpower ROM (when the bugs are worked out), and maybe some sort of sound ROM. I also need to get more understanding on some of the other vernacular like what exactly a "dirty flash" is.

sony ric is a layer of security for sony roms so that they can protect nfc and fingerprint stuff. samsung and htc have there own variants as well.
yes lol the big red lettering is there to make you read, although hes not far off on the melting your phone part, the s810 is ridiculously hot.
the xpower thread doesnt not include the drm backup instructions because: 1) you need bootloader unlocked to flash it. and 2) because it includes the drm fix in it so you dont have to backup your ta keys.
the fingerprint sensor bug is on any bootloader unlocked phone, the hardware fails after x amount of hours and requires a reboot to work again. xpower is a stock rom, the only thing different is its pre-rooted, de-bloated, and deodexed for xposed to work. we have a separate thread for the fingerprint sensor bug and its been solved.

Sony RIC main function is to disable /system write even you got root permission(you still able to do /system write but after a reboot will restore to original). There is a workaround but very trouble, TWRP recovery file manager can bypass Sony RIC(it works in the old day for me, not sure about now). BTW, all 3rd kernel should be disabled RIC nowadays. For any regular computer, there is no hardware or software lock to prevent you gain root access in linux but there are many such trouble stuffs in the android world... lol
I'm running XPower 3.0 Full as a daily driver since June and been very happy. Battery life, stability and speed is good.
Please note, that you MAY lose your warranty when you lose your DRM keys. That's why I didn't unlocked my phone before there was a way to backup TA partition. Now I'm after warranty repair, and before it I was able to fully restore stock ROM with DRM and all features fully functional. In my country, there is only one Sony approved repair center and they check DRM keys before repairing anything - even if it's mechanical fault.
When I had Z1c in KitKat days, it didn't had dm-verity and Sony RIC. It was possible to gain permanent root with bootloader locked, so I was happily using stock ROM and kernel. In Z5c case, first thing I tried was to do the same and it was possible (just backup TA, unlock bootloader, and flash TWRP with patched kernel (dm-verity and Sony RIC disabled) to begin with), but going XPower way was much more confident - I didn't had to think about removing every bloat app. I just flashed lite version in June and I'm using it till this day without any problems at all
Another thing is that you lose OTA (Over-The-Air Update) functionality when you unlock bootloader and disable Sony RIC and dm-verity. Updating to newer versions of firmware, even on stock ROM is problematic when you modify it.

It's simply not possible. If you are rooted you can't apply OTA updates and neither should you.

How do I enter recovery mode on a SONY Xperia Z2 LTE tablet SGP521 (not rooted)?

So I have spent literally days, in an ultimate attempt to upgrade to a ROM of Android 8.1
I have never attempted anything like this and it seemed to be straight forward enough to try myself. I quickly realised that I needed to install TWRP on my tablet. Then upon hours more research I learned that to do this, the tablet must be rooted. But it cannot be rooted if it is running Android 6.1.0, which it currently is. So I need to downgrade it to it's original firmware, something like Android 4.4.1. But then one of the steps of doing this is that it also needs to be rooted. To root the device I must enter recovery mode. I have tried the physical button pushing method so MANY times, I have sore hands now. It didn't even work once. How else can this be achieved on my device? What other methods can I use? I have heard of something called ADB.... or something like that. As a complete beginner I am unfamiliar with how to use this. Could someone please help me?
I don't know if this information is also handy, but the bootloader IS unlocked. I was able to do that about 6 months ago, when a friend of mine attempted unsuccesfully to put a custom ROM on it.
First time sorry for my poor English...
What ROMs do you use now and what do you want?
I've been dying for two days, but I've been updated (Stock 4.4.4 to Custom 8.1)! I also use SGP-521.
It was a nightmare, but it did. If I can, I will help you!

Sony Z2 Horrid Device

The Sony Xperia Z2 tablet has got to be the most horrible device in android history to root or install a recovery on it. The process and the complexity of it is just horrible. You daren't ever make the slightest change to a rom or anything in twrp as it just screws everything up on this device. I can't count the amount of roms i've put on it just to totally trash the device and you have to start from scratch. Either you put a new rom on, it wipes the recovery, you have to piss about using flashtool to flash some other ftf on just to get into recovery, then you have to then flash another tft to get root, the list just goes on and on. I don't even know why sony mobile even bother offering the bootloader unlock option in the first place, it's an absolute nightmare. It's basically you can have root with the official stock firmware, if you want a custom rom spend the next 2 weeks trying to get supersu installed on it. The most horrible device I've ever come across.
Then sell it :laugh:
Somehow I cannot share this view. Running Carbon ROM with Magisk without any issues. For a more than 4 years old tablet the Z2 stands its ground, I don't regret having bought it.
Just hoping that we'll get Pie...

I've tried Carbon and would love to use it but it just screws up the tablet after install and recovery gets wiped so you can't even go back to restore a back up. You then have to reflash using Emma then back into flashtool to reflash the tft to get recovery to work again because flashtool ends up reporting back that the current tft is not compatible with the device. It's a finicky device to root. It's got to be the worst out of all android devices. E.g my Samsung s9 had it rooted and flashed with a custom rom in around 5 mins. No matter what firmware is installed. Sony decided that after 23.1.A.575 or whatever rooting was not possible after that. Also every method on here telling you how to do it is different to each other and inconsistant. I tried 23.1.A.575 root for UK and it would not allow for twrp to be booted into. I had to use xperiafirm to download the Taiwanese version so I could get the batch script to allow recovery so holding down power on volume down would allow twrp to load. It's just a painstakingly horrible device to root to get something so simple. But yes your right probably best time to get rid and something different. Sorry for the rant it's just been a frustration for me.
Sorry to say so, but rcstar has a very good step by step description on how to install the ROM. I followed it to the point and have no issues whatsoever.
TWRP, Magisk and Substratum work, like everything else.
It's not a device which is easy to mess with, you are right. But it's doable.

I've followed so many without much success. I tried the solution by kulvertti to the letter and the tab was having non of it. I think the problem also is that a lot of the links are dead to the specific tft you need to download so getting the exact version is tricky. The only one that has worked for me is the Taiwanese rom then using the recovery script by danalec to get Marshmallow flashed which is what I'm running now. So I made a back up today and thought OK let me try carbon because I can get all the nice customization options like being able to choose a dark theme for the settings menu instead of piercing white. What is it with manufacturers wanna make every thing bright and painful on the eyes. Anyway downloaded gaps wiped system etc installed rom and once it loaded the system was all unstable and lost root and recovery. So I give up now and have to accept I can only have marshmallow on it.
Danalec has a very simple root method for Marshmallow in the general section. This is one of the best tablets out there by far. Build quality doesn't come close with other brands.
