First, sorry for my poor english. I am Brazilian ...
I searched the forum but have not found a way to relock the bootloader without the TA backup. And the topics I found the link was already broken.
Would anyone answer me?
The concern is that the update came, but I can not update. And come to think that maybe JB version 4.3.

You can't. There is your answer. TA backup is a must in order to get DRM keys back. Without them even if you can lock the bootloader only thing you will acomplish is the fact that you will not be able to flash ROMs or kernels on it.

Hey mate, you should have researched a bit more before unlocking your bootloader cause it's simply not possible to relock it without a TA backup.
And also the 'update' isn't JB 4.3 xD it's still at 4.2
Incase you didn't know, you can still update your firmware even with your bootloader being locked. Just flash an ftf, grab the latest ftf here
And flash your phone via flashtool. Incase ya didn't know how to, refer to this tutorial
Hope that answers it.

You are right, friend. I really should have researched better before unlocking. But my biggest concern is with the possible updates that can go for the XL.
But at least I can update it according to the standard TFT that are on the forum via Flashtool.
Thank you again!

Read my post again and then read it slowly yet another time. Speaking of stupid....No point in relocking since DRM keys are gone without TA backup. So yes, don't post if you don't have a clue about what the hell you are posting about.
... i think u should read it. if he want to he CAN and also if he needs to give the phone to repair then he can do that with locked bl. there is like 90% they will not check if there are drm keys or not... just bcoz DRM keys are gone doesnt mean that he cannot lock bl. so stop spreading dumb answers like that he cannot lock bl and dont say it next time cuz he can always lock bl if he needs to. There is always point in relocking bl eq updating with seus or pcc

I think I might be able to get your TA backup and make your phone fully running, however, I need to ask few questions :
Did you unlock your bootloader the official way (via Sony ) or via flashtool ?
Did you update your firmware using your Sony PC Companion ?
If you unlocked your boolater the official way (Sony Way) and Updated the firmeware using Sony PC companion, I guess there is something that could be done! TA tool may still be able to locate your backup in your phone!
I never backed up my TA and I know it was a mistake but I managed to get my phone relocked (updates and everything works from Sony).
I am not sure how this worked but I recently relocked my bootloader by flashing ftf file which I made from Sony Update(and I unlocked it the day I bought which was like months back without back). Lucky for me, it also included TA in the ftf file name as UNKNOWN, DATA, etc
After flashing that, I used flashtool to relock my bootloader and I even managed to make a backup of TA with DRM keys!
I am not sure if that be of help but I explained the procedure if you want to give it a try! Do write me back if it works for you!
Steps :If you Unlocked bootloader the official way (SONY website). It might just work if you didnot even!
Try TA tool for backup TA. If that doesnot work, do this :
Update or repair your firmware using Sony Companion
Make FTF using flashtool from your Sony Companion backup
flash FTF without deselecting any date ( all including TA and UNKNOWN)
Use TA tool to make a backup
Relock bootloader using TA Tool or flashtool (I am not sure if DRM keys will be replaced but I guess I should make your phone running fully)
Good Luck!

DRM keys will not be there. To lock bootloader is easy, just use flashtool. But without TA backup there is no point since those keys are unique to every single device out there. Without them there is no gain whatsoever in locking bootloader.

Updates will not come WITHOUT DRM keys. Only way is to flash FTF with Flashtool. You are a true pole.

Thank you for your contribution but I am afraid I will have to completely disagree with you!
I unlocked my bootloader around the time there wasnot Xperia L forum on the XDA and I am very sure that I DIDNOT backup my TA at all. I was careless and I was working on ROM so I needed it. I did it the official way though!
I relocked my bootloader using flashtool and I did get all the updates from 4.1.2 to 4.2.2 (till the lastest one till date using PC companion). And Ironically, I am always on the first update schedule to receive updates in the UK whilst many regions do not have got any update at all.
However, in between I got an update which I couldnot update. I had long forgotten about my unlocked bootloader and thus I was puzzled what was I doing wrong. Then, out of now where I checked for my bootloader status and found it was UNLOCKED. I again relocked it with FLASHTOOL. I updated to latest firmware and unlocked it again.
Then, I thought maybe I should backup my TA. I knew I had lost my DRM keys so I just gave it a try using above method and it WORKED for me as I had been making backups of my FTF all along for my device! My bootloader is locked now and it works perfectly. There isnot any problem that I face apart from proximity bug (which is firmware related)
I am afraid that either you prove me wrong by giving a PROOF of a time where you lost your TA and YOU had to buy a new phone
OR
Donot write something that you are partially sure or you have heard from somewhere!
@Redzo and u are a true idiot (kid) who is even too scared to shown his real nation. and yes they will come withought drm. for me pls just shut up, cuz i dont want to argue with dumbass like u anymore. kids shouldnt talk u know...
EOT
thank you all.
I did not want to cause confusion, guys.
It worked for me! Got my TA back
I have now created a TA backup how to know if it contains DRM keys?

Hello!
I bought a phone, with unlocked bootloader and root. Z3 D6603
I dont know exactly how the previous owner unlocked BL etc.
But I flashed it to 23.1.A.1.28 lolli, fixed super SU and dualrecovery.
The thing is, I now want to return it to stock, so that i can get OTA updates by Sony Companion, and i have no idea how to do so.
Searched the forums, and found a lot of info, but I dont want to brick or ruin anything.
Do I need to flash stock firmware without root, remove dualrecovery or relock BL, or maybe all of it?
I posted this earlier, and im not sure if I explained it right, I said I wanted a step by step guide.
What I meant was a guideline in what ORDER to do stuff, not how to do them.
Is it enough to relock the bootloader, and then use Sony Companion to update, or do I need to flash something, maybe go back to original recovery first?
Help is sincerely appreciated !
PS: Sorry for posting again, but I dont know how to change the headline/bump the post, and need this done ASAP, or else I wont have a working phone in a few days. ( Change of sim card)

Nothing. If it is unlocked and you dont have backup of original TA partition. There is no help. You can't get you DRM keys back and without them you cant relock to original state. And majority of Sony stock fw simply doesnt provide OTA for unlocked bootloaders, except for the new Sony Concept ROM.
You may try to download Androxyde Flashtool as it provides relock function, however it doesnt restore TA. If it brings OTA back not sure, because I always backup my TA so just try it.

Hi guys. I need to know how to lock BL let you can't recognise it. Can you please hele me? I have D2403
If u relocking you bl then what is the point of unlocking of bootloader...
If u want unlock then u can unlock it by androcyda flashtool for xperia...
If u have your drm keys.. Backup then it ok.. U can restore them and get fully stock device if not.. Relocking will not do anything like that.
As far as I'm aware either re-lock via flashtool or by restoring the drm/ta keys which re-locks it. Unless you have the drm/ta keys pointless re-locking it to be honest as without the ta keys updates still won't work anyway not that we'll be getting Anymore updates should be a simple process either way though..
Hey guys,
How can I root my phone without unlocking my bootloader? I can't seem to find anything useful.
Thanks.
You can't. Unlocking the bootloader is the required first step to rooting.
Some think a method may appear in time, but I'm not convinced.

I'm not convinced too, but I unlocked my bootloader since I really want to have Viper4Android at least and to be able to remove some apps. How can I know if I properly relocked my bootloader? I have backed-up my TA partition.
Marshmallow is hard to root via system modifacation
This is why systemless root exists, if you was to do this on a locked bootloader device you may brick the device hence as of now and probably a decant bit into the future a unlocked bootloader is required
However you can downgrade your firmware and backup your TA Partition and restore at a Later date
You can do this via a tool called Ivyroot

Since when is it possible to brick an xperia with a locked bootloader? As far as I know, back in the days I used to be flashing almost everyday without any chance of bricking my device. I know I can back-up my TA partition, but how am I supposed to know if I properly re-locked my bootloader?

After relocking the bootloader you can check in service menu or try to repair ur phone with xperia companion, if you succeed than ur bootloader is locked successfully.

Well, a soft brick ain't a real brick. So bricking it is basically not possible depending on how you look at it.

That your TA partition is wiped. Re-locking the bootloader and restoring the TA partition are completely separate steps. If you didn't make a backup of the TA partition before unlocking the bootloader, it's gone forever.
...It's gone forever. But if you want to stay rooted, and get all Sony's upgrades like Camera enhancements or other TA provided tweaks you can use DRM Key Fix or install a custom ROM which include it (like RomAur which is great)
I have managed to relock it, you gotta have the stock kernel installed before you can relock it. That sucks :3
How about downgrading to 32.0.A.4.11 firmware? Can we root after downgrading to that with Kingroot?
Just as mentioned above. I dont mind waiting but just wanna ask is there anybody able to get it already? I've done some google, some pages offer a very 'detailed' instructions like just install TWRP using fastboot method then flash the SuperSU binary then bingo!! Some others state unlocking BL is required. Since to me xda is the only reliable source so I guess I will be looking for answers here.
Cheers
since the Z3+ and newer devices, root with lock bootloader is impossible at least for now.
btw, unlock bootloader is so easy for root, why not? Warranty?

I've been waiting for over 3mths for some progress on backing up the ta keys on all the x range(I have the xa) I don't see it ever happening to be honest and I've made the mistake of loosing ta keys before I won't be doing it again.

Hi all.
I've got my XZ since one week now, and I'm missing the possibilities of rooting my device.
My Z2 was LB, so I never could ever try to unlock my bootloader. therefore, I don't know anything about it.
I've read a lot of thread here and there, and some points are not that clear to me.
Will the procedure of unlocking the bootloader erase everything in the phone (like photos, contacts, etc...)?
Unlocking the bootloader will kill the DRM keys forever, if I understood well. but flashing Androplus Kernel will recover them, right?
Is it possible to relock the booltloader after? if yes, will the DRM keys be restored?
Last thing, to be sure of what I should do.
1-unlock the bootloader with IMEI via sony site.
2-install TWRP via adb command
3-flash Androplus kernel.
Am I right, or do I miss something?
Thanks for your help, and sorry for the noobish questions.

Hey sensei_sai,
Im unsure if unlocking will erase your data but its always best to backup everything in the internal memory just in case something goes wrong.
Androplus will NOT recover your DRM keys but kernels with DRM fixes try to replicate the features that are permanently lost as a result of unlocking your boot-loader.
In the future it may be possible for you to re-lock the boot-loader but even then this wont restore DRM keys, the only way to restore DRM keys would be to back up your TA partition (This contains your DRM keys) before you unlock your boot-loader but to do this you need root access with your boot-loader still locked.
How to backup TA
Unfortunately at this time nobody has figured out a way to get root with a locked boot-loader although a newly found exploit (Dirty cow) may help us do this very soon so if you care about re-locking and keeping your DRM keys I advise waiting until a locked boot-loader root solution is around!

Too bad for the TA partition.
So we have two possibilities. Take the risk of loose some features forever, but benefit of the root or wait till someone make some magic to use an exploit to obtain root without unlocking the bootloader.
Risk and go... Or wait and safe... Dilemma...

I think that the era of DRM lock is over, we've been using DRM fixes for all the latest xperia phones, the dirty cow is a bad exploit and it's more dangerous than useful.
I was unsure about unlocking the bootloader but now that I did it, I rooted and I regret nothing, the only downside of unlocking is the warranty loss, but who cares as long as the phone doesn't magically explode.
