About rooting. - Xperia Z2 Q&A, Help & Troubleshooting

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

1) Give it a try. Should work on all xperia devices.
2) Yes you can. Since xperia go got official jb update and you don't have to unlock your bootloader to install jb, there is no problem. You can backup keys with both ics and jb
3) If you unlock your bootloader you will void your warranty in any case. Backup ta partition will not make you loose bravia engine when after unlocking your bootloader you want to relock it. Won't save your warranty this mod

Thanks for your reply you have cleared all my doubts but another question if i restore the ta partition and relock bootloader i have my warranty back correct?
It doesn't matter afaik restoring ta partition to get back your warranty (maybe I am wrong though). What really does matter is relocking the bootloader.

You can be right(I'm the noob XD) but i have read if you not backup the ta partition your warranty is void. So relocking the bootloader is insuficient, you have to relock bootloader and restore the ta partition .
The tool creator said:"Backup TA can backup and restore the TA partition of the device. When you create a backup before unlocking for the first time, then you will be able to restore to full factory state (including a locked bootloader). This means all DRM keys intact, Bravia Engine working in Album and last but not least your warranty when needed":good:

I already read this thread mate, that's because I told you that I could be wrong.
Ok then, there is no reason for not trusting the tool creator. Just root and use this tool. Save and put keys in a safe folder and enjoy

What I have to do before sony service?

Hi.
I have some problems with my mini jack. When I plug headphones it sometimes work sometimes not. I think it is messed up. Phone still has waranity, so maybe they fix it.
My question is:
What I have to do before I leave my phone in service center?
Do I have to relock my bootloader or just flash stock ICS?
will they check software if phone has hardware problem?
Thanks in advance!
Cheers

You should relock the bootloader and restore drm keys of possible.
Relocking bootloader is a must as it is the first thing they check.
Relocking the bl should be enough but sometimes sony checks more deeper for the drm keys. So if you have backed up then restore your TA.
And you should flash the latest stock firmware.
They must probably will check bootloader status.
When my touchscreen wasnt working correctly, i just flashed ICS and relocked bootloader without restoring drm keys (i didnt backed it up when i unlocked). Apearrently they didn't checked the software and just sent me a new phone.
If you just relock the bootloader they can check the drm keys and will know you unlocked it before. But I don't see a reason why they will remove your warranty because of that, giving the fact that nothing software-wise can screw your headphone jack.
@Twski
Depends on the employee who checks your phone. If he checks for drm keys then he knows that you unblocked your bootloader and your warranty is void.
But mostly they just check the bootloader status like they did last time.
And unlocking the bootloader will void the warranty no matter what the problem is. While unlocking the bootloader they clearly told you that.

Thank you guys for reply!
I will relock bootloader, flash latest stock and go to sony service.
Edit: And if I want to unlock it again after it return to me, the procedure is the same like 1st time unlocking?
Yes.

relocking the bootloader????

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.

Root question

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

[Q] About bootloader unlock

Hello,
I've searched forums but since I dont trust my english, I couldn't find a thing. So, apologies if this was asked already.
Is my warranty void upon requesting bootloader unlock key, or is it when I actually unlock it with that key? Because sony seems to save imei codes in their site. I live in Turkey btw.
Also, another un-related question, is my phone diving-proof ?? I mean, I've shot a couple of videos and photos in pool, but I'm scared to just jump on it with my phone ?
Unlocking your bootloader wipes your TA partition where your unique DRM keys are kept
Xperia Z2 is IP58 Certified to water resistancy meaning it can survive underwater at 1 meter for 30mins or less distance for more.
Thanks for the reply.
I know, but since I am rooted on locked bl, and backed up ta partition, it should be ok to unlock, right? I mean if I restore my ta backup, I get my warranty back or..?

Yep, restoring your TA relocks your bootloader so flash a stock kernel before you restore.
