Yes you have to restore your TA partition. Use the very same tool that you used to backup your TA partition.
Now if you do not have your TA partition then forget about it. Just go over to Sony and pay the cost. If not get a new phone.

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

You're welcome mate, it's a pleasure. For any further help let me know.
Hi,
I had the S3 and switched to the Z2 last month. So I am new to the bootloader thing.
Is it right that I can relock the BL by restoring the TA partition for warranty for example?
Or can Sony see that I've unlocked it?
just be sure to backup your TA, and you can go back to your original undetectable state
.....
Hi thx for your reply
So when I restore the TA the BL becomes locked again? Or is it possible without locking it?
And do I need a new backup when I update from .402 to .314 ?

Why do you need unlock at all? Exist root methods without unlocking...
When I want to install a custom kernel for example.
Restoring the Trim Area locks the bootloader.

Does locking the BL wipes data the same as unlocking it?
Yeah m8, re-locking your bootloader will wipe your phone so, as always do a backup first:good:
I want to unlock the bootloader of my Z2 but I'm scared about relocking it with TA Backup. Has anyone tried it? If so, how did you do it?

what? i dont exactly understand, here is some info to clear up some doubts or potentialy answer your question. ;D
if you had a backup of your TA restoring it will relock your bootloader
relocking your bootloader doesnt bring the contents of your TA partition
and for me relocking i used flashtool as i do not have a backup of my TA partition
relocking or unlocking your bootloader wipes your device data so backup your internal storage before doing

you've answered my questions! thank you!
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!
E2303, 8GB. Phone image was downgraded temporarily to root with xperiarootkit & backup TA. Latest stock image (with carrier branding due to connectivity issues without it) was (re-)installed afterwards, bootloader unlocked, TWRP installed & phone re-rooted. TA was then restored. SIM card is perma-locked to carrier. ( )
Phone is rooted, TWRP works, bootloader status is still unlocked (???), TA partition exists, but DRM features like ClearAudio+ etc. are missing from the settings. Anyone have any idea what's going/how this can be fixed? Does Backup TA not restore correctly (or worse, backup incorrectly!!! This would be VERY bad!) on the M4 Aqua?
I unlocked without backing up drm Keys and i have normally working phone with Clear Audio+...
What next features dont working u?
Normally you have to re-lock your bootloader for those DRM-related features to work again. At least that's how it was on my Xperia SP.
Can anyone tell me all DRM features on this device please?

That's the thing tho: TA Backup didn't relock the bootloader.

if you did a TA backup when the Bootloader was locked and if you use the TA Backup tool to restore it, it will lock the bootloader again.
thats how it worked for me on my Xperia z and now Xperia M4 (E2363)
How did you backup and how did you restore? The restore perhaps didn't work because the TA partition has to be set to writable (via blockdev command).
This is just a guess. I didn't unlock yet but did a backup of TA (manually, not using some batch files because I don't trust them and I run Linux and Win batch files won't work).

My apologies for being a month late with this.
Flashtool provided the option to re-lock your bootloader. So, once you've restored your TA backup you can then use flashtool to re-lock.
Hope this was useful. :fingers-crossed:
Cheers,
Re-locking using flash tool only locks the bootloader but does not restore the DRM certificates.
after re-locking with flashtool you can use PCC to repair the phone and get OTA updates, but the DRM certificates are not restored, they are lost for good.
unless you have used TA Backup (http://forum.xda-developers.com/showthread.php?t=2292598) to backup the TA partition when the bootloader was locked and the certificates were all ok and valid, you need root with locked BL for this to work.
Restoring the TA partition with TA Backup tool, locks and restores the drm certs again root is required for TA restore.
i know because mine worked.
