[Q] New to Z2, few Questions - Xperia Z2 Q&A, Help & Troubleshooting

Hey guys,
I am new to the Z2 and Sony devices in general. I rooted and flashed Samsung and HTC devices before, so I am not a total beginner.
Basically what I wanna do is: Flash the eXistenz Rom with locked BL.
1. Flashtool
Okay, so I need to downgrade. I already downloaded the flashtool + a .314 firmware for my phone.
Do I leave the flashtool flashing options just at the defaults? I mean do I really don't wanna check things like partition and TA in the "exlude" field.
Wouldn't that mean that it is going to flash TA and re-partition the storage (doesn't really sounds like what I want). I read some threads,
but they're always like "Yeah, just click flash", so I thought I doublecheck.
2. Rooting
Okay, so theres many root methods out there, which one can you guys recommend? What root method does flashtool use?
3. Nut's
If I do all the above mentioned, I could just flash a ftf file and my phone would be completely stock right? Nut's is also some sort of hack which doesn't alter the original recovery in the recovery partition on my phone, right?
Thanks in advance.

1. yes leave flashtool options at default (it will wipe your internal storage)
TA partition isnt touchable realy, if your DRM keys exist they arent affected by using flashtool
2. Rooting depends on your firmware, 167 or newer isnt rootable via tool so you will have to folow a slightly longer task to root, easy root tool is recomended (check the info thread near the top of QnA section)
3. [NUT] Is a user who makes recovery for locked bootloaders, You need to be rooted to be able to install his recoveries
flashing a FTF will completly reset your device to stock
[NUT]'s Recovery for locked bootloader doesnt affect the boot or Recovery partition hence its ability to run on a locked bootloader

[Q] Rooting, unrooting etc - new to Xperia Live

Hi. I am new to Xperia Live with Walkman and I have some questions.
1. If I root my phone, then is there a way to unroot it and restore warranty?
2. Here http://forum.xda-developers.com/showthread.php?t=1695603
Unlocking bootloader lets you install custom kernels and ROMs. If you do it via official way, you lose your guarantee and your DRM keys, that means you will not be able to use TrackID and some other little features. If you patch it via unofficial way (test point method) you lose nothing. Anyway, if you don't intend to change your ROM, don't unlock it
Click to expand...
Click to collapse
So, what are official and unofficial ways? And don't I have to root phone to unlock bootloader first? Or I have to unlock bootloader to root?
OK, I've read about all of them and quite understanded it.
3. Could someone give me quadrant (may be standard, but the newest one) score from fast rom for my Live?
4. To get into recovery I have to flash it first or it have it installed already as it is in some samsungs? And do I understand well that to flash recovery (or use it to install rom) I have to unlock bootloader?
5. If I flash unofficial rom (first unlock bootloader etc) and want to get back to stock one and locked loader and have warranty back, then what should I do. Is there a way to do this?

Ok, I've read about some stuff. Now I know that I unlock bootloader and flash a kernel with a recovery. But how can I get official, signed, stock rom and how to install it?
And before flashing custom rom do I have to set partitions, as it was with HD2? Like /system /cache /data etc...

Partitions are already there, ROMs only affect /system(few also /data), /cache and /data must be formatted if you install another ROM.
Official, signed, stock ROM can be downloaded via Update Service and PC Companion. You can create a Flashtool .ftf file, there is some information on the information about it.

So I can flash custom rom and there will be possibility to get back to stock one? And what is this flashtool?
Ehhh, I need to read more
I have a tft file with a stock rom, but is there a difference between branded software and unbranded? I use Tmobile PL so when I will flash any other stock roms will they accept warranty? And when is recovery being removed? When flashing stock rom?
And could you please tell me more about creating tft (I haven't found any info about it on Xperia Live)

OK, I've found out how to make ftf. But does it restore warranty? And what with these differences between branded and unbranded?

OK, I'm such an idiot I've just looked into Tutorials | Firmware | FAQ and found that http://forum.xda-developers.com/showthread.php?t=1568792

Root procedure for GPE?

I know there's a thread in general that tells how to root.... but it bounces around between models and was hard for me to follow what steps I need to do and what I don't. If someone could someone please post just GPE steps here in a newb friendly fashion I'd be happy to donate a few bucks for a beer or a cup of coffee

At the moment there is no root exploit for GPe so in rooting it you will lose the TA partition and the DRM keys, and may lose warranty, you have been warned!
So here goes:
Unlock the Boot Loader with flashtool (padlock icon). you will need a key from the Sony dev website http://unlockbootloader.sonymobile.com/
Download and copy to SD card SuperSu Update http://download.chainfire.eu/382/SuperSU/UPDATE-SuperSU-v1.93.zip?retrieve_file=1
Boot a 4.4 recovery & recovery using flashtool or fastboot (this last one is a command line tool) DONT'T FLASH http://forum.xda-developers.com/showthread.php?t=2548092
fastboot boot RevolutionKernel-ZU-v#.img (replace # with version no.)
from recovery flash SuperSu Update
Enter recovery when you see the GOOGLE or Sony logo and the LED light turns on. Pressing VOLUME UP key for CWM & VOLUME DOWN key for TWRP
I believe that DoomLords kernel will also work above and can be flashed http://forum.xda-developers.com/showthread.php?t=2579005
For this kernel do as above but you can do "fastboot flash boot boot.img"
This is off the top of my head, and LordManhattan's guide so not tested by me. Any questions just ask

thanks for the reply, I guess I'll have to do a lot more reading, don't know what a TA partition is and what the impact of losing it is, also the DRM keys would that mean I would lose the Bravia Engine for video display? As far as booting into recovery I wasn't aware we had one available. I thought root was needed to install recovery to make a recovery boot (sounds like a catch 22) I'm kinda freaked of bricking a device with no warranty and it being my only phone.
Only reason I need root was to run gesture control I sorely miss from my Nexus 7. I'm probably better off just getting used to the fact I wont be able to use gesture control on this device
making good on my word you should have a donation show up for a beer or cup of coffee your choice

The bit about recovery was for when you had it installed after rooting. But read up an the drm and TA issues and then make up your mind if it's worth it for you. Yes you will lose xreality/bravia2, but they only work on video and gallery, not on the display
Sent from my Xperia Z Ultra using Tapatalk

I did it. Could give a damn about the DRM keys for sony's "xculsive" apps.
I also didn't care about the bravia engine then again I can't tell a difference in my devices display while watching movies cause I'm not a videophile.

The farthest I have gotten has been unlocking the bootloader thanks to your guide.
Past that (I'm using Sony MObile flasher by ANdrodyde) I haven't figured out how to get a kernel on there so I can root.
I presume I MUST root BEFORE flashing a rom. Even if I do get to rooted status I believe us GPE guys have to have a special boot.img file if I'm not mistaken

No you dont have to be rooted to flash a rom, just have recovery.
Yes the boot.img is different on the GPe to a stock c6806. DoomLord has made one that works from what I have read

Steps 2, 3, and 4 are the parts I'm stuck on.
I've tried not only DoomLords kernal img but also revolution kernal. Neither of which "stick" the flashtool says it loaded it. The phone restarts but there is no recovery.
I don't understand where to put the 4.4 recovery. Your method is the only one I've read that says I need a recovery. All others say flash a kernel either DoomLords or Revoultuion.
---------- Post added at 07:13 PM ---------- Previous post was at 07:12 PM ----------
And it gets stranger.
If I put the either kernel on the SD card, it won't flash. If I put the kernel on my computer in the correct folder, then it will flash to the phone. Really strange.
But phone will not stay on kernel. It acts like it takes it, reboots, and back to stock kernel.

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!
Don't forget to make a donation or thank the OP in the original thread
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

[Q] Rooting Z2 after .167 (help needed)

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)

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

If you have a unlocked bootloader you can just flash a recovery and use it to flash A root zip

Bootloader cant be unlocked at all unless YOU unlock it via flashtool or fastboot

Thanks for the links.
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?
(when I will pass all of this I will write it over here)

Flash pre-rooted rom and flash a 167 FTF (exclude system and data)
If your on unlocked bootloader flash recovery and then use recovery to flash a pre-rooted rom

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.

Confirming everything about rooting... (and a bit more)

I have found many sites with conflicting answers, so please don't tell me "google is your best friend" for my silly/already asked questions...
So first what I have: a 5 month old, non modified M4 aqua (E2306), bought from a Canadian carrier. The firmware version is 26.1.A.3.111 (bootloader locked). My goal is to root my phone when I update to MM (using the method PiSpecialist has posted, I cannot post links), but I haven't done so for the fear of losing TA partition when unlocking BL. There is currently no way to root MM with locked bootloader.
Now, my questions:
1. When I unlock my BL, I will lose the TA partition (DRM keys) of the device. Yet to back these up, I need root access. Should I root my device while it is still on Lollipop? There are ways to root BL Lollipop correct? If so, please link a preferable way to do this.
2. Will I receive OTA updates after rooting my phone? If not, I should download and flash firmware from Xperifirm?
3. Will I lose root when flashing new firmware (e.g. flashing MM to a rooted Lollipop device)?
4. Is it dangerous to flash official firmware to a rooted phone? What is a safe way?
I found that dealing with TA is dangerous and can hard brick a phone. Anybody found a reliable script/tool to do this?
So this is pretty much what I am planning to do so far, if the above is correct:
Root my phone while it is still on Lollipop with a locked bootloader.
Backup my TA partition.
Get MM (from either flashing, or OTA, depending if I still get OTA updates)
Unlock bootloader (as there is no way to root for locked bootloaders in MM)
Root phone while it is on MM (if I don't keep the root after updating from lollipop)
Restore TA partition
DONE!
Not as many questions as I thought.... Any other advice/things to look out for would be appreciated

Theres no way yet to have root in mm /system, it needs to be in kernel and you cant use custom kernel and restore ta. All the questions you did are already answered in forums.
But in case your interested ill tell you what i did step by step to have original TA part with drm and "tunned" but unrooted /system.
Keep in mind that your warranty is void, you will loose all your data and you may brick your device. Messing up with TA partition is serious and dangerous stuff. The following steps are just to tell you what i did.
If you want to do so, do it at your own risk.
1. Clean install LP 3.120 via flashtool wipping user data.
2. Root with rootkit 3.xxx and installed twrp for BL
3. Backup TA
4. Unlock bootloader and install MM fw via flashtool
5. Now with BU installed boot.img and recovery.img
6. Now with root, deleted unwanted apps, installed adblocker, installed xposed, tunned some settings/apps etc.
7. When /system was how i wanted, i made a backup via twrp (data, system, cache).
8. Clean install LP 3.120 again via flashtool, wipping user data.
9. Root via rootkit and installed twrp for BL.
10. Restored TA partition
11. Restored the backup via twrp and SHUTTED DOWN the phone because itll not match with the rest of the fw.
12. Installed MM fw again via flashtool but this time, excluded /system part and DID NOT WIPE user data nor Apps log. (as ive restored MM /data backup before)
13. Started the phone.
Now i have MM with drm, locked bootloader, unrooted, xposed working with few modules, adblocker applied and some other mods. Also i receive updates via sony apps such as whats new. And the low speaker volume seems to be fixed.

Thank you.
What adblocker can be install?

Btw, false alarm regarding speaker volume, it still saturate with bass at higher volume resulting in a lower and kinda cracked volume output, it may need to be tweaked, or even try to port LP audio parametres to MM rom, if thats even a thing and possible, until sony fix it (if they do lol). Ive tested a variety of songs

Theres no method at this moment to put su binaries in /system, but if you dont mind you can keep the root as long as you dont restore your TA / lock bootloader as it needs a stock kernel signed by sony.
I enter twrp recovery in MM by holding power+vol down

I don't understand about "excluded /system part"? Flash only system file or everything

No, you exclude system as you restored it early via twrp, flash the rest of the firmware like modem, kernel etc. Remember to dont wipe data and apps log also
Edit: if you flash system youll loose the changes you did thats why you need to exclude from bundle when choosin in flashtool

Your welcome. Yeah if someones finds a way to do the classic root like in LP this will be rootable for sure.
At least in the meanwhile we can have ads blocked and xposed with some modules and still keep bootloader locked with drm keys to keep functions and receive updates.

This is what im going to do...
Root bootloader locked in LL
Back up TA
Unlock bootloader
MM through flashtool
Root MM (boot.img , recovery.img) (This IS what you did by flashing these, right?)
http***://forum.xda-developers.com/m4-aqua/general/root-t3421932 (going to use this boot and recovery .img)
Chang/add to Marshmallow firmware
At this point, the device should be rooted on MM, with UB TWRP and SuperSU.
Now, is it okay if I just restore TA partition NOW, instead of going back to LL? I'm not really interested in saving OTA updates... speaking of which, how did you manage to still get them? I thought as soon as you modify your device, you are excluded from OTA updates...

Yeah you root mm by flashimg boot.img.
First, some people reported that is recommended to restore TA partition in the same firmware as you backed them up. Second, if you restore your TA and you have custom boot.img (like that one to get the root) your device will not boot

you can do it from rooted LP with twrp, first wipe data , system and cache, install MM fromzip (you can create the zip with PRF creator using the dummy_flashable.zip instead supersu zip) after MM its installed you can now install xposed, and other kind of flashable mods, lastly, power off phone and flash tft skipping system.sin
you will have android modded and untouched bootloader without root

id rather prefer to do the system changes with root in the mm firm, but sounds like a good method for those ones that cant unlock the BL.

If on rooted 5.0 all you need to do is flash a pre-rooted mm zip via recovery on lollipop, no need to unlock the Bootloader for root unless you have a device that has drm-verity security activated.

Oh yeah I completely forgot about that... someone released a prerooted rom about a week ago on the forums. This will less complicate the process for bl locked rooted MM, thanks!
