Hi all,
I was wondering whether it is possible to un-root the Xperia Z2?
i.e. warranty issue bla bla bla ...
For instance I have rooted my Z2 - running a custom rom ... then what I would like to do is go back to stock rom and unroot the Z2?
Thanks!
Yes, you can unroot. You can also flash a stock ROM.
To root you have to unlock the bootloader. If you do this via the SONY website, there will be a record that you have unlocked. I would suggest you use Flashtool to unlock and then relock, if and when you want to.

To root you first need (at this point in time) to unlock the bootloader. To unlock the bootloader, you request a code from Sony. When you unlock the bootloader, it will show up in service menu and you can't undo it. From that point you can root/unroot as you please, but the bootloader remains unlocked and it will be like that nomatter what you do. So, if anybody from Sony Service checks your bootloader and you unlocked it, you might loose your warranty (as per Sony website). It doesn't matter you unrooted your device.
Thanks

If I Unlock The Bootloader Will I Get The ICS Update This April ? Or I Still Get It If I Dont Unlock It. *Im Not A Professional Rooter*
Xperias with unlocked bootloaders won't get official updates.
#correct if im wrong!
you will get the update. just install it with pc companion. if that wont work, youll get the flashable files in dev section.
don't worry someone will make ftf file and you can also update via wotanserver.
If you unlock the bootloader, then there's a risk your phone will be bricked when you update firmware over the air using seus or pccompanion. You should update it offline using flashtool and ftf firmware file.
If you unlock it and use a custom rom, then I don't think you would get official update notification anyway.
If you're not planning to use custom kernel or custom rom, then I suggest you only need to root it .

There's a big risk on unlocking the bootloader because we wont be able to receive official updates or even void our warranty with our manufacturers. Make sure that you know the advantages and disadvantages of unlocking the bootloader before proceeding.

but if u only unlock the root u receive. because i have a sony ericsson live walkman 3.4.2 rooted but last week it ask me to update. Is it secure to update a rooted device??

Hi All,
I'm using Sony Ericsson Live with walkman. I'm very new to terms Root, unlock bootloader and all. But I would like customize the os.
Could someone help what is rooting and bootloading etc?
I've seen somewhere people saying i used different ROMs..Please let me know different types of ROMS and how to install those..i'm planning to try one..
which should be done first either rooting or unlocking bootloader ?
Thanks in Advance..
You should use the search here on xda or search on Google there are many guides that explain rooting etc
If you are new to this I'd advise you to root first and install a stock based rom. If you want to have a rom running Jelly Bean, unlock the bootloader then, but remember unlocking the bootloader will void your warranty!

If u are planning on unlocking on your bootloader, better backup ur TA partition first if u are still under warranty. For rooting, u can use doomlord's rooting kit.

My bootloader is locked. And following the Sony steps.. It says it won't unlock.
In device, tap Service info > Configuration > Rooting Status. Bootloader unlock allowed says No,
All my favorite apps won't work properly without root.
If anyone figures a way to root it.. I'll give you $100.

Wait why won't it unlock? Does your phone say its bootloader can't be unlocked or did you just have trouble unlocking it?

My phone says bootloader cannot be unlocked. In Canada the Z2 started as an exclusive with Bell Mobility.. the Sony store versions are unlockable though.

$100.... it's sounds good? Okay from my experience I bought my XperiaZ from Australian Telco before and it said Bootloader unlock allowed:No
but when I flashed official generic ftf using flashtool. It's said Bootloader Unlock allowed:Yes. So if you can take a risk try it(do it by your own! and don't forget to back up!)... you might try to do that. Luckly my XperiaZ2 is bootloader allowed one. Hope I have a chance to get 100bucks

This is very dangrous, this depends on the contents of the FTF and i wouldent recoment this at al
Have you tried flashing the German DE generic FTF, i think it has stuff for the TA partition
This may do your job
I still dont recomend, do this at your own will if you know how to unbrick a device
Although i would try it but only because i know how to unbrick a xperia (lol this part usualy takes a while)

I noticed him that it must be done by his own.... But he asks us to is there are anyway to do that? so I just posted the way I did.
I am not recommending him to do that.... I just simply answered his question. Always flash ftf w/o TA and partition.
It is recommended everywhere and If once he started to searching about flash tool it is warned by everyone.
You can't back up TA partition w/o root. So I don't think there is any way to get XperiaZ2 to back to completely stock.
(Although i would try it but only because ←What does it mean? It doesn't make sense for me.)
Well, I tried to flash the stock FTF.. same version as my devices. It errored.. and I am now bricked.
You can't modify an FTF and flash it to a bootloader locked device, modifying it will break Sony's signature verification
I'm guessing there's no way to unbrick?

How i unbrick my devices usualy (if they are locked bootloader)
Pt1
Unplug device totaly
Hold power
Hold volume up
Wait for it to buzz 3 times in a row
(rubber bands usualy help)
(ensure battery isnt killed from doing this (low charge)
(aka dont leave rubber bands for several hours)
Pt2
Download and install sony PC companion
Go to support
Go to repair device
Folow instructions

You'll need to find Sony's signing key then. Good luck with that
Aww.... We warned you.... it must be done by your own and not recommended. Try SEUS.... (Not sure if it works for yours....
Everything what you've done with flashtool will be avoid your warranty..... I think when you downloaded flashtool they warned you again....
As EnviousData warned you too.... even I did not recommended to do that.... dear....
Ok, I managed to unbrick.. back to bootloader unlock allowed: No
Still.. If you guys have any ideas how to root.. $100.

Honestly i say keep your $$$ and wait for a exploit or root method of sorts
Me and my FTF will be a while and Z2 Development has started very slow and may be a while before anything of the sorts comes avaliable
I suggest if you realy want to root try exchanging your device for an unlocked one (or unlockable :/)

I have a couple questions to ask about rooting this device.
I have a UK model with unlockable boot loader. Everything stock on the device.
1. Is there a root out yet that doesn't require unlocking the boot loader?
2. Can I root without voiding my warranty?
3. Can I easily unroot and leave no indication of it being rooted, to make a warranty claim if ever needed?
4. Do mobile banking apps still not work on rooted devices?
5. Does rooting slow down your device?
Thanks in advance
Sent from my D6503 using Tapatalk
1. Yes there is a full root thread on the Original Development forums for the Z2
2. No, your warrenty will void with root however removing and flashing a stock FTF it will restore your warrenty as your Z2 no longer contains modified content
3. You can unroot via the app and there will be noticable changes unless you used root to modify but then you can flash a stock firmware
4. They should. Very few apps actualy check for root
5. Rooting does not slow your device

So I can root without unlocking boot loader, and then just unroot to restore warrenty if/when needed?
I have looked through some threads and a little confused about if the phone has to be downgraded to root? The build number ends in .402, so can I root easily?
Thanks again, I do appreciate you taking the time to help me
Sent from my D6503 using Tapatalk
Yes you can root without unlocked boooader as of posting this
You can restore warrenty by removing root
I think you can stay on 402 to root, not sure, look at doomlords thread in original development

I never ended up rooting my device, but decided now is the time.
I am on 17.1.1.A.0.402
Bootloader is unlockable, but currently locked (and will be staying that way.).
Does anyone know if there is a way I can root it without unlocking bootloader and without downgrading firmware?

yes you can root easily now with locked bl (thanks to all the devs that contributed btw), you can upgrade to .314 and root that easily too, you can then restore ftf to stock and keep warranty. or you can also root, then backup TA, then unlock BL and do whatever you like. you can restore that TA backup later to get locked bl again and restore ftf to stock and keep warranty.
Thanks guys.

Before you root, you should read the threads in the dev section as potentially you are unleashing a beast which can brick your device.
Hello everyone. Seriously need help here with a xperia z ultra c6883. I bought it off someone and tried to do an update from the phone but it keeps saying 14.3.A.0.757 could not verify. FYI, I checked to see if bootloader is locked and it says yes. I downloaded rootchecker and it says device not rooted. I dont know where to turn. i just want to be at stock.
android version says- 4.4.2
baseband version says -8974-AAAAANAZQ-10270045-39
kernel version says - 3.4.0-perf-g8c33725
[email protected] #1
build number says_ 14.3.A.0.681
What does this all mean? Am I rooted? Do I have an unlocked bootloader? Can I just go back to stock? Or is it easier to just upgrade to lollipop?
Try locking the boot loader and then connect to Sony PCC and redo the phone.

you can use flashtool (http://flashtool.net) to relock the bootloader, but if you download flashtool you may as well just use that to update the ZU to the latest FTF from here (see the FTF thread in the dev section)
Is there a how to video on the process? Ive read things like ( I need to know what rom im using or drm keys etc etc) Dont know what to do.

In the FTF thread there is a video
As you brought the ZU already bootloader unlocked the DRM keys are gone (unless the last owner still has the backup). Just flashing a FTF doesn't relock the bootloader, you have to use the BLU icon in flashtool. The BL does't have to be locked to flash a FTF but it does to get/use the updates directly from Sony.
Any more Q's just ask
Ok thank you for the info. If you dont mind I might hit you up tommorrow for more Q's.
