Lost BE After bootloader Re-Lock - Sony Xperia ZR

I know It sounds strange but when I relocked my Bootloader with my TA i lost bravia engline
although I did that before and BE2 was working on 4.3
Any Suggestions I tried Relocking and reflashing
tried Several TA'S I had made
no luck
And BE works in the movie app

when you unlock your bootloader your drm's gone for good!!
if you didn't backed up your TA then it's lost forever

Actually I have 3 TA's which don't work
Forever No BE2

EVERY phone's TA signature is unique. u are lucky not to hardbrick ur phone...

All 3 are made from my phone
One when I had 4.2
one after flashing 4.3 (It's After restoring 4.2)
One before Flashing 4.4
I know very well what would happen if i flash someone's TA into my mobile

did you get any errors when flashing?

if you have backed up using TA backuper you can flash back to 4.3 then restore your TA,
if you have backed up using flashtool, DRM are lost! you can't restore your DRMs

Backup TA

Fixed after restoring 4.3
Unlocking on 4.3
Flashing 4.4
Rooting with CWM kernel
Restore TA
System Restore
Wait for 2-3 H and it will work by itself

[Q] Help with Reverting/Relocking

So I installed CM10.2 on my phone. For that I had to root and unlock my bootloader. I didn't really like it to be honest so I decided that I wanted to go back to stock rom, the problem however, is that i'm not sure how I should do this. I made a backup of my TA Partition so I also could get my DRM keys (Bravia Engine, etc) back. I don't know what I should do first and I was wondering if there is someone who could help me through this process. Do I first need to flash stock kernel, then flash stock ftf, and then install that TA backup in order to relock my bootloader? But I thought I needed root for this, if I flash a stock ftf then root will be gone right? So many questions
Thank you in advance

Thank you for your response but this is only relocking etc. My problem is that I don't know in what order I should do things. So far I think I should do it like this (but i'm not sure, so i'm asking for someone to tell me if it's wrong) : 1. Simply flash a stock ftf (with the ftf the stock kernel will be installed too, right?) 2. Relock bootloader 3. Then apply the TA Backup to get the DRM Keys back.
Is this the right order to do things? Will I make an expensive brick out of it if I do it like that?
Flash a stock FTF and root it (or flash a pre-rooted stock based ROM through recovery ). Then restore TA, which will automatcally lock bootloader and restore DRM keys

Official 4.3? YES you have to.
Leaked?? U dont have TA partition at all (after unlocking BL)
Late reply!!!...
What @smogf said ^^
If you are flashing the official one you need to
If you are flashing the leaked one you need unlocked bootloader so the TA is not there ...

What does the ta partition have to do with updating to 4.4?
This is my Question. So the 4.4.2 Update do not update the TA Partition

I'm guessing not as the only ta backup I have is from 4.3 and I've relocked my bootloader on both 4.2 and 4.4 using the only one backup without any problems
Your backup should work fine, I was on CM11 but decided to go back to stock yesterday. I restored my TA backup from 4.2.2. Effectively soft bricking the phone while relocking the phone and restoring my DRM keys, then immediately used flashtool to flash the global 4.4 update. All worked fine. On first boot it updated my NFC firmware which I believe is TA linked but its running perfectly now.

[Q] Going back to stock

Hey guys,
Have a quick question here. When it was possible to (properly) unlock bootloader. I backed up my TA partition, root, unlock and custom ROM e.t.c.
Now, I wanted to test out stock 4.4 from Sony. Do I simply download the FTF and flash it via Flashtool? Will BIONZ e.t.c. work? Or do I have to go back to 4.2 stock, restore TA then it will work?
Or simply flash something like RomAur 4.4.2, and need not worry about TA (and BIONZ e.t.c. will work)?

Bionz is gone after you unlocked your bootloader. You'd have to restore your ta backup to get it back

It's always been possible, but there was an issue regarding unlocking bootloader at first with the camera bug.

This is what I meant. So, to have bionz, I would have to restore TA, relock bootloader and not have custom kernel (like Doomlords). And just flash something like RomAur.

Justt resotre the TA, that relocks your bootloader anyway
RomAur is not a stock rom, flash a FTF after retoring your TA, it will also install the stock kernel you will need on a LB

Yep, from what I was reading, I have to flash the same version of the stock that I backed up TA with, then restore TA (which will re-lock bootloader), then I can flash the LB version of RomAur.
However if I want to use DoomKernel, I will need an unlocked boot loader. Since I am currently running SlimKat, it would make more sense to just download RomAur and flash it and DoomKernel via CWM and not worry about TA restore (since I lose it when unlocking).

Yes, but you said you wanted a stock rom, and RomAur is not stock (It is stock based, but it is not stock)
If you want RomAur just flash it.

Yeah sorry. RomAur (stock based). Just flash it. Simple. If I want TA/BIONZ though, will need to go completely stock + locked BL.

No, just restore your TA, ensure you have a stock kernel. You can still flash stock based custom roms on a locked bootloader.

It's only for one phone, if you flash other drm keys from another sp you will hard brick your phone.
