[Q] TA Partition backup on new electronic card - Xperia SP Q&A, Help & Troubleshooting

Hi all,
I made a backup of my TA partition some time ago and never took time ti unlock my bootloader.
I had to send my SP for repair, and they changed the "electronic card" (I believe this is the motherboard). The phone was working but it would not charge anymore, so I guess the power circuit was burned.
My question is : will my TA partition backup work on my new hardware ? I don't want to do it again if this is not necessary, I just want to move ahead and unlock my bootloader.
Thanks for your answers !

I would bet that "DRM" keys contained in a TA partition are unique and different for every device. otherwise, we would know what those keys are, and they would not have their said purpose. however, backing up the TA partition takes about few seconds, don't see why you wouldn't make a new backup and be on the safe side. you know, just in case...

I thought I had to be root to backup the TA ? So I have to first root, backup TA, unlock bootloader, re-root...
I think I'll do it, but I'm a bit lazy and I don't like to make unnecessary stuff.

What do you mean ? Maybe YOU should RTFM ?
Quote from http://forum.xda-developers.com/showthread.php?t=2292598 (backup TA 9.9) :
Q: Do I need root for this?
A: Yes, you do need root for this to work. I would advice to use @DooMLoRD's excellent Easy Rooting Toolkit for this, when not already rooted.
So yes, there are a lot of steps to backup the TA. Since I'm on .254, rooting is not just one click away, I have to flash kernel, root, reflash kernel.
If someone told me "your backup is fine because the key is linked to that stuff or that stuff and not to the motherboard, so go ahead" I would have avoided unnecessary hastle AND many people would have learned something in the process, like what the TA partition keys are linked to.
Nothing unnecessary, except maybe for your post, right ?

Dude THINK!
The post you link to says to ASK questions about backup TA in that thread, I believe it even has been answered before. :victory:
If you would have used your brain logic would have told you the encryption is unique, you can't just copy the TA partition of one device to another come on, its so simple.
Besides that? Why even bother to unlock the bootloader if you dont want to go through the hassle of installing new / other roms? You know what this website is about? Not about being lazy and stupid but about being inventive and curious. And of course people need to share their information, like I said before, people should take the time to READ, not be LAZY.
So don't be lazy. There's enough fat people in the world Enjoy your phone!:highfive:

Okay guys.. As members, both should know better.
First of all. If you go to this thread: http://forum.xda-developers.com/showthread.php?t=2292598 and read a bit you would know that making a TA backup is VERY IMPORTANT TO DO!
Also read a bit futher. Root is required to use this tool..
And a extra detail YOU CAN NOT I REPEAT CAN NOT USE THE TA BACKUP OF SOMEONE ELSE TO RESTORE YOURS BECAUSE IT WILL HARD BRICK YOUR DEVICE
As stated in the Q&A of that thread:

It is important to read the entire OP/thread to prevent this kind of questions Also read the replies.. They can answer questions for you
Also as an answer to your question:
NO you have an entire new internal system so the files are diffrent. If you havent unlock your bootloader yet make a backup first before doing so and remove the one you already have. I think you will hardbrick your device when you restore your TA backup from before the repair

I know better ^^

OK take it easy guys, it was a simple question meant to have a simple answer.
I should have asked my question in the "backup TA" thread, that's true, but I don't think it was a stupid question.

Thanks, that's the answer I was looking for.
I know TA partitions are unique, the question was whether an electronic card replacement necessarily meant a new TA partition. Does it mean everything changed, from IMEI to hardware keys ? Well, the answer seems to be "yes", but I don't think it was SO obvious.
Thanks again for the answer.

Yes a new motherboard means also a new IMEI..

When decrypting files after official update one of the files seems to hold TA information... no root required....

You are wrong, the only thing that file includes is a customisation ID reset, besides, writing to TA is not the same as reading from TA. I'm sorry but this just isn't going to happen.

Thanks for input.
Today I learned something new.
Well i wanted to try to root manually. But that requires an unlocked bootloader. But i cant backup the ta without root. So it becomes a chicken and the egg problem.
So i was just wondering if theres any other way to back up, but i guess theres not

I guess you don't search and read properly. You can root your phone with Locked Bootlader.

no offense:
with this kind of attitude, technical progress would just stagnate.
don't get me wrong, i really don't want to offend you, but i'd rather support people who are trying to do something "the other way" instead of turning him down.
i'd go even further and give him probs for digging in deeper rather then just relying on tools made by others.

No taken, just read what he asked in the first post. Then ask your self, is that easy to extract the FTF and Root it "Manually" and then flash it again or even extract just the system.sin, switch to insecure and do all steps to get root. Even an ignorant like me understand in first place if something like that will be possible we will not have all this trouble to get root. Ending this story how you can ask just for Backup TA without Root and not explain what you REALLY want to do? Which help you get? Come on!

I know I didn't explain myself fully in the initial question. I was just looking for a simple yes/no answer, I didn't think the context was that important to the question.

I think you don't think enough, I do not stop your development, you do starting from a point where is there no way out.
This is the ONLY solution which you have, from a guy without experience like me, Root your phone with the method by NUT for Locked Bootloader, there is no other way for your purpose, then when you are rooted easily you can Backup your TA and DRM keys. Now you are in safe place and you can Flash Back Stock Rom from PC Companion or from Flashtool some FTF from XDA and you are ready, Stock like NEW with Locked Bootloader ready to Unlock it and experiment what you have in mind.

[Q] New User! Where should I start?

Hi, i just got my Galaxy S3 (SPH-L710) from Virgin Mobile today. I wanted to know where to start reading in this forum in order to not screw anything up on my phone. I am talking about things i need to be aware of when rooting or flashing roms so i don't brick my phone. Thanks guys!
You should definitely start here: Backup IMEI and also back up your EFS ! Theres plenty of guides around here, so help yourself

you should ALWAYS start from there with any android phone(not that, but something like that). i started from there...now i see posts on forum about guys that have problems with IMEI or phone won't boot cause EFS partition is damage(or something)...
after that just READ CAREFULLY when doing something...read the tutorial until you fully understand it... and have patience...don't hurry things.

EFS / IMEI losts are uncommon on brands other than Samsung. But i agree, BACKUP EVS AND NV.
Second, if you're not on 4.3 official, DO NOT UPDATE TO IT via official methods. You'll get knoxxed.

[Q] Restoring DRM Functions (UB)

Hi guys.
New to this forum (well, back after a good 3 years) and I decided to pick up an Xperia Z1 to get back into Android. Did the usual that I do with my Android phones, and quickly went ahead and bootloader unlocked.
Little did I know that there was such a thing as DRM Keys and TA Partitions that required backing up. Yeah, stupid me being all excited on Christmas Eve.
What I'm wondering is, will I be able to use this guide to restore functions of the camera and other hardware/software related bits (BionZ, Noise Cancelling etc) without a valid TA Partition backup and DRM Keys? I've read through a fair amount of that thread looking to see if anyone has done it in the same situation as I'm in, and well, I've found people requesting .FTF with TA Partitions in them (Doesn't that brick your phone?).
If I can possibly restore with a .FTF downloaded off the internet, I'll do so but input would be helpful so I don't go bricking my new device... I'd like to somehow at least restore the camera stuff so that I don't get horrible low light photos, and from there install a custom ROM like iHackers.
If it helps, I'm on build number 14.4.A.0.157 (4.4.4 I think).
Cheers.

[Q] Is there a way to return to 100% stock after rooting/unlocking?

Hi guys,
I want to root my device using the guide posted on this forum, but I'm not sure how I would go about restoring it to factory state to regain my warranty in case I need to send the phone for repairs. I previously had a One M7 and the whole process of rooting and flashing stuff was child's play, but it seems much more difficult with the xperia, espeically there seem to be nowere near as much guides and resources.
Has any of you done what I'm asking about? Is it even possible? This question is literally the only thing holding me back from rooting the phone, as the uselessness of my SD card is starting to seriously annoy me and the fact that we were promised the lollipop update in February and it's still not here nearly halfway through March.
Use Sony PC Companion to flash back to completely stock.

Firstly downgrade to a rootable firmware(ftf) using Flashtool. Then root. Backup TA partition (most important step). After this, even if you unlock bootloader, your TA partition is safe. After that if you want to restore warranty you may go back to the rootable firmware using Flashtool and then root and restore the TA partition. Viola you have your warranty back. Restoring the TA partition locks the bootloader and gives back the DRM keys and so you get your warranty.you may even flash the firmware all over to unroot (just to be on the safe side)
DO NOT UNLOCK BOOTLOADER BEFORE BACKING UP TA PARTITION OF YOU CARE ABOUT WARRANTY

Help a BIG noob with Root.

So, I want to root my Xperia Z3 Compact. 6.0.1 D5803 .291.
I found few text tutorials here on this site, yet these don't help me at all, most of the words used in these threads i don't understand at all.
For example; "Backup your DRMs" And I'm Like "Backup what?,Backup how?"
If it comes to android I'm complete noob, and I don't know anything about this OS.
So I'm here hoping someone will waste their time trying to help me understand anything.
Edit: If this post has wrong flair, is in wrong sub or something is wrong with it, please point it out. Thats my first time using this site.

So first of all you asked the question in the right sub so don't worry about that.
Regarding the DRM keys,here is a brief explanation.
So the guides you saw probably say that you should unlock your bootloader,and when you unlock your bootloader you lose the said DRM keys.
When you lose the DRM keys your camera becomes a bit bad with it being very bad in low light situations and as well some of the Sony features won't work.
There is a zip you can flash to return the camera quality BUT it only works on stock ROMs.
So I would only recommend unlocking the bootloader if you are going to install something like Carbon ROM or LineageOS.
Now if you want to avoid unlocking the bootloader and just using the stock ROM there is a way to root it on a locked bootloader,you can find the method in the General subforum.
But do remember you can only install stock based ROMs on a locked bootloader,else the phone will be bricked.
I hope you understand now.
To start stay with locked bootloader and follow this tut. Do not unlock bootloader at this time...
This is about to Root and get TWRP (custom Recovery) and stay with locked bootloader...
Get familar with "Flashtool" - Everything needed is linked in below mentiond thread.
https://forum.xda-developers.com/z3-compact/general/guide-newbshow-to-291-mm-z3clocked-t3536395
If you have root go on and back up TA partition.
