Root question - Xperia Z2 Q&A, Help & Troubleshooting

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

[IDEA]Root By Unlock then Relock Bootloader?

Hi guys, i have an idea. Will the idea of unlocking the bootloader and then do the root (with recovery enabled kernel that is) and then relocking (restoring the TA partition first) the bootloader work? I am a little bit confused with the fact about the DRM kind of things, since i don't want to lose it so if we could restore it back later then why this technique was never discussed? Please give me any information :angel:

Oh yeah i forgot.. this trick will not work if you haven't done TA backup wouldn't it? :-/ I have done that before so i guess this idea won't work for anybody without TA backup i guess no?

flashing the TA partition and locking the bootloader, and then flashing a stock FTF base/firmware will make your device exactly how you bought it.. It will allow x-reality to work in both movies/album, as well as track ID working.
- This technique has been discussed in previous threads.
== Do a search and you will see there is a FTF flashing guide. flashtool guide both in the android development section.
A guide on just about everything in the general section... have a look...
However even an unlocked bootloader will allow the x-reality engine to work with videos. But will stop netflicks from working. So there are probably a few apps out there that need a locked bootloader to work properly.
To have a locked bootloader you need a stock kernel. It will need to be signed, so even a boot.img or kernel.sin would be fine. Just needs to be stock.
- You could Root, backup TA partition, unlock bootloader, and then lock bootloader again. But that still uses a rooting tool.
forgive me if I'm wrong (and someone correct me) but we cant do a TA back up without root.
When I was looking into the ZU the only way to root was to unlock the bootloader then flash a new boot.img (?), this avoided vroot et al, and the issues that we seem to have atm but did mean that the first to root lost their DRM keys (TA partition) with the rooting

You can downgrade to lower firmware anytime without root, than use vroot if you don't mind some risk, than backup TA

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.

About rooting.

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

SGP621 Root Question

I am a rookie with these things and I would like to get some clarification.
I want to root my tablet, I am very satisfied with it and its system, all I need is to root it without touching my bootloader and drm keys. There are so many threads about it claiming its possible without unlocking the BL and I am not sure which tutorial should I use to root my device.
My device is LTE version, nothing modified and firmware is 23.0.1.A.0.16.

you can try Towelroot as I see Z3TC is supported but I didnt test it on my tablet
where did you see that z3tc is supported by towel ? i can't find a device list or so.

There is only one method at this time to get root on this tablet and this method involves unlocking your bootloader after doing a backup of you DRM keys (TA partition). Once you rooted your device with the unlocked bootloader you can reflash the TA partition and the bootloader will be locked again with all DRM keys intact as if you never unlocked it in the first place, but with root. Towelroot is not supported as the kernel exploit that was used is patched since nearly half a year now.

[Q] Root latest 23.1.A.1.28 *and* backup DRM keys?

I've seen multiple threads on rooting the device both here and on other sites and all of them conveniently leave out mentioning the fact that you're irreversibly ****ed if you don't backup your DRM keys first.
With DRM keys, I find the thread for Backup TA only to be told the tool is no longer maintained, and I haven't come across anything else that's similar.
The instructions for Backup TA say that you need the device to be rooted in order to perform a backup. If I understand correctly, rooting requires unlocking the bootloader first - and doing that will invalidate the keys, so epic Catch 22 right there.
And yes, I know that this question has been asked before, but I'm looking to see if there is anything new as of today, i.e. July 2nd 2015 that is specifically applicable to the very latest firmware. So is it possible to root the device without losing DRM keys or having to downgrade to last year's firmware first?
If you download an app called "kingroot" I think, you will be able to root on the latest firmware, however, there are roumors who says that this method sends your IMEI to a company in Japan or China or something.
Sent from my D6503 using XDA Free mobile app somewhere in Norway
You could just download some older firmware, install it without unlocking the bootloader. Then root the device using some other method (because on older firmware there were exploits available) and backup the TA partition (DRM keys) right away. Then you're able to wipe the device again, install the latest LP firmware and be happy with a backup

You have it confused. Rooting using exploits like towel root or kingroot doesn't unlock your bootloader and you dont loose your DRM keys. If you want to unlock your bootloader you will have to goto Sony website and type in your IMEI and follow a procedure.
Try the steps mentioned in this link, it'll help you root your phone without unlocking your boot loader. Once you have root and recovery, you can go to recovery and backup only the TRIM Area which is the TA partition.
