There isn't much reason to unlock boot loader specially since root is available on all firmwares.
If you really want to unlock the bootloader for some reason then you can always backup your TA partition and then Unlock bootloader. Then if you ever get the need for warranty you can flash the original FTF restore the TA backup. You will have your warranty back.

Thanks mate will try to install now the official 5.0.2 from sony
unlocking your bootloader grants freedom and easier at loss of your warranty and some xperia features
however staying locked lets you keep your warranty and xperia features but its generally annoying for me atleast

I have unlocked the bootloader and now i found that there are ways to root to root phone without unlocking the bootloader is it possible to relock the bootloader without losing any phone capabilities.
If you've already unlocked there's absolutely no point in relocking it, you get more freedom and benefit more from an unlocked bootloader eg custom kernels and roms
i just want to know what is the way and suppose i want to give them for warranty repair so i should be prepared lol

If you used TA backup after rooting and BEFORE unlocking, you can return the phone to a fully LOCKED state as if you had never unlocked it.
If you didn't do a TA backup, you can only relock it and thus the reseller/repair centre know what you did.
i never made any TA backup it wasn't available that time there was no root that time without unlocking it.

Then you can't return to completely stock. The relocked notice will give you away.

Look at Xperiafirmware.com -> "Sony XPERIA Z2 D6503 - Android 4.4.2 - firmware 17.1.2.A.0.314". There is a solution to re-lock the bootloader.
Hi all.
My questions should have already been answered but I want definitive and up to date answers, since this will be my first sony device in years and I wouldn't want to waste my money.
So, here we go!
1) Can I root my device without loosing warranty?
2) I saw there is a ta backup utility, if I use this my warranty will be okay if i restore before sending in the device?
3) I found a 4 month used one, at a good price and I want to check if it has been rooted and in conclusion if the warranty is valid or not. How can I do this?
Again I am deeply sorry for asking!
EDIT:
Found this, is this valid?
http://forum.xda-developers.com/showthread.php?p=53908905&highlight=warranty#post53908905
Can I root and just unroot be ok?
What about flashing roms on locked bootloader?
If I restore my stock rom would I still be covered as long as we talk about warranty?
Sony has changed their warrenty recently
Rooting doesnt void your warreny but breaks ota updates untill you undo and unroot the device
You can flash a FTF using flashtool to restore totaly stock firmware if you want
Xperia warrenties are valid from when you purchase
Given proof of purchase and date of purchase your warrenty will start there
2 years insternational warrenty for all devices
If a device has been rooted it will most likely have superuser or supersu app
And if it doesnt you can just check using root checket, and even then you can just flash a FTF file to fully factory reset the device

What about the TA Partition?
Is there any way to check if this is ok or not?
Unlocking the bootloader voids warranty, right?
P.S. Could you send me a link about Sony changing it's warranty, can't find it.

Ta partition, its currently imposible to check its contents
Unlocking your bootloader will wipe your TA and void your warrenty
The warrenty info should be somewhere on the sonymobile website

Oh.. Relocking your bootloader doesnt bring back its contents, aka DRM keys
Also Nothing is lost exept warrenty when unlocking your bootloader however this varies depending on your country, branding or version of the unit
Most versions just lose X-reality

Got it.
If I had backed up the TA Partition (which contains the DRM keys) and flashed stock firmware, restored the keys and relocked my bl, would I be ok?
So the only way to lose warranty is unlock the bootloader?
If i flash a rom, on locked bl, my warranty would be ok after I unrooted and restored factory firmware?

Restoring your TA relocks your bootloader
1. Backup TA
2. Unlock bootloader
2. Rom/kernel flashing time
3. Flash totaly stock kernel (from ftf)
4. Restore TA
Restoring your TA brings back your warrenty :/
Flashing a rom on Locked BL i dont know that affects the warrenty because ive never fully read it/cared for it
Restoring stock fw should reinstate the warrenty because the device isnt concidered modified
I think to get the best info, go and find the sony mobile warrenty info

Now all my questions have been answered.
Thanks man, much appreciated!
In xperia z2, is any security system against root like the knoxx of samsung? Which has a counter and void the warranty?
If not, the root void the warranty?
And the last question. There is already the root for version 4.4 with unlocked bootloader?

No need, xperia security is among the hardest to crack, not happened at all since 2011 and only 1 person ever did in 2011
It can be rooted eaisly but as said security isnt a problem with root or modding or bootloader unlock.
Root and bootloader unlock voids warrenty but you can reinstate your warrenty by backing up your TA before unlocking bootloader
You can unroot and restore your TA later
Xperias can be restored to a 100% factory state, there are no flash counters or anything of that sorts
Any questions... Just ask

What is TA? And how i can backup it?
Sorry, I'm a newbie in this area ...
I searched for index topics, but i don't found ... There is here a simple tutorial on how to root the z2? And installing TWRP mode or clockwork (I think that's how you write it).

1. TA partition contains drm keys and other unique numbers to your device (these existing upholds your warrenty and upholds some xperia features such as X-Reality and PS4 remote play)
This link you can use this tool to backup TA but you need to root first
http://forum.xda-developers.com/showthread.php?t=2292598
2. Root via root tools (general section or development sections) (this depends on firmware version blah.bla.314 firmware or before is rootable with locked bootloader
3. Cwm or twrp requires a unlocked bootloader however if you have root you can install [NUT]'s dual recovery
I've had my z2 for two days now and previously flashed my HTC one XL so I'm not super new but still pretty green with it all. Will it matter being an Australian phone for the root etc? I don't plan on flashing a rom at the moment I'm pretty happy with the stock firmware
Cheers
Hey, i got Z2 1 week ago, and i want to unlock my bootloader so i can root and install recovery. Coming from other android phones i know the bennefits of rooting and installing a custom recovery, but what happens if i unlock my bootloader?
My bootloader is unlockable but what do i loose besides the warranty? I read in 1 thread that i can loose the quality of the camera. is that true?

You know you don't need to unlock your bootloader to root and install Cwm right? Also it is always advised to root, backup ta partition and then unlock bootloader. If you do that, you can restore your TA partition at a later date and recovery your drm keys.
I have mine updated to 5.1.1 and the bootloader is unlockable. However, the rooting instruction is confusing for this version.
I am looking for the definite solution for rooting (if it is required to unlock the bootloader, should I backup TA partition first?) 100% stock 5.1.1.
Frankly, I don't want to mess with Kingroot or similar tools from China.
I'm interested in this as well. Sent for warranty repair and came back with 5.1.1. Looking for recommended way to root and backup TA (though I have the original backup somewhere)
http://forum.xda-developers.com/xperia-z-ultra/general/guide-how-to-root-install-recovery-t3210207
I managed to root the device. Here is a guide:

This is how i did it...downgraded to 4.4.4 and root it,TA backup, unlocked the device, updated to 5.1.1 with stock ftf installed the new recovery an flashed the TWRP after that flash the SuperSU zip and done...

That's a waste of time. OP has an unlockable bootloader, so he just has to:
- Flash recovery
- Flash SuperSU
- Reboot

Unlocking the BL is still FAR quicker than going through that hellish process for locked bootloaders. It's like trying to juggle with your hands tied to your back, but they're not really tied. Not sure why WE are arguing though. You provided a guide for a locked bootloader, while I gave one for unlocked. What OP decides to do is currently a mystery.

Here is a deal: unlocking bootloader will remove DRM key. The only workaround is to backup TA partition. However, doing such also requires root, so you have to root before unlocking bootloader.
Don't you know your method is no brainer???! But dealing with DRM key is another story.
Hello !
Frankly you should try with kingroot it's not really a big deal it's quicker and don't worry you will not mess up your phone. I did the same on mine, and it's quick...

Kingroot does not work with 5.1.x, sorry.
I still have to rollback to 4.4.x and use dualrecovery method 3.

Okay, so roll back to KitKat, root, backup your TA, unlock bootloader, and then update to 5.1.1 again. You'll then be able to just flash a recovery and root. If you don't care about the TA partition, then unlock bootloader and flash recovery and root.
Be aware that if your device is still under warranty, it'll be voided the second you lose the DRM keys (TA). If you're not under warranty anymore, it doesn't make any difference. If your device has to go into repairs down the road, it won't matter since you don't have warranty either way. But if you have, it's a good idea to back it up.
Also, the X-Reality engine etc. were at one point dependent on the TA partition, but this changed on KitKat, so X-Reality still works on an unlocked bootloader (even though it's really bad).

Here is what I did as mentioned on the post linked on earlier post.
Download the latest ROM with Xperifirm, and 4.4.x ROM found in a sticky on the general section.
Pack the 5.1.X ROM as flashable pre-rooted.
Use Flashtool to rollback to 4.4.x, completely wipe, made initial setup and enable debug, and install recovery.
Install pre-rooted ROM through TWRP.
Backup TA partition and device data.
Unlock bootloader.
Restore TA partition and device data.
Done.
