Restoring TA backup = relocking the booloader
I don't think there is any other way to relock the bootloader, so how would you like to relock it?
Thanks for the reply I was going to use Flashtools to relock it. Cause of the camera issue I thought locking bootloader and restoring TA where completely separate from each other.
Also if you don't mind I'm on 4.3 unlocked with DooMKernel v4 and want to flash stock kernel how do I do that and where do i get. A guide on xda said if I want to relock I had to flash stock kernel.sin using Flashtool I don't know how to do that all I is how to flash a kernel using fastboot which requires me to have the .sin file which I don't know where to get it.

The stock kernel is inside the ftf of the firmware, so just select the firmware in flashtool and on the right hand-side you will see a list of contents of the ftf that you are about to flash (system.sin , userdata.sin, kernel.sin and so on) . Exclude anything that you don't need to flash under the exclude tab.
Just a word of advise, make sure you relock the bootloader on the same version of the firmware that you made the backup on. So if you backup up TA on 4.2.2 relock it on 4.2.2. There seem to be some people that have had issues when they tried to relock on the newer firmware.

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

Thank you very much, I tried this and it worked.
I'm on ihackers 2.1 ROM android 4.3
rooted
unlocked bootloader
I wanted to go back to stock to C6902_14.2.A.0.290
I found the method but I'm not sure if this is the right way http://lionking853.blogspot.co.uk/2013/11/how-to-go-back-to-stock-firmware-on.html
and if it is the right way, after going back to stock ROM, will my phone unroot and relock again?
Can I just go ahead and do this or must I relock bootloader first?
please help me since I never done this before, only rooted and unlock that I did.
Thank you so much folks
Hey u have to flash 4.2 first pure stock by flashtool using ftf,root it install recovery only if uve got TA BACKUP.Make sure ur on pure stock before restoring TA.Restore TA backup will relock bootlader then flash 4.3 ftf.If no TA backup then u can directly flash stock 4.3 ftf through flashtool & relock it using flashtool

If you have an unlocked bootloader, you will not be able to update using PC Companion. I didnt know all this **** were involved in Sony phones.
I had unlocked my bootloader a couple of days back, didnt know I had to backup my DRM keys and ended up losing my warranty. Now I cant even update my phone using the official updating method.
BTW... the recovery is bundled with the kernel, thats why people refer to it as flashing a kernel instead of recovery. I didnt know this until 2 days back.
Thanks

If you do have a TA backup then you don't have to do anything else then restoring it on a stock rooted firmware..If you don't then use flashtool to relock it..

If I am on a Locked Bootloader and on a rooted custom ROM, will Sony PC Companion detect my phone when the next update comes??
This is stupid. If you are in 4.3 (.290) with un-locked boot loader you cant update via PC companion or SUS.
I ended up going to 534 (4.2) via flashtool. Root it, restore TA backup and then use SUS to update. And flashing the latest 4.3 via Flashtool din work.
No PC Companion or SUS won't detect your phone.. You've to manually flash a valid ftf from Flashtool.. Then you can connect & update your phone through PC Companion or SUS..

Look at the root. 266 thread for unlocked bootloader..
It's exactly the same, the only difference is u have to flash the. 201 kernel again after finish rooting to experience improvements in the update..
Just a few questions please help. To keep our phone's warranty, we need to back up first the TA partition before unlocking right? I read and watched tutorials on how to back up but it needs a rooted phone so i search again on how to root, but unfortunately it requires unlock bootloader. Am i right guys? I'm using .201 all are stock and locked bl. Help guyrg.

So, I'm on Central Europe 1 4.4.2, with doomlord kernel and root. I have a backup of my TA partition before unlocking bootloader.
I want to update to Central Europe 1 4.4.4, using the flashable zip that was posted and the stripped ftf.
Should I flash the stock kernel from FTF 4.4.2, restore my TA partition backup and update? Or update to 4.4.4, and after that restore my TA?
What are the bricking risks? Should I wipe everything? :crying: SO MANY DOUBTS
Why relock?

If you want to go to totally "out of the box" device and have OTA update info and few other things you just said then yeah...
First flash ftf and stick kernel and then relock bootloader...
If you restore TA and leave custom kernel you could have serious problems...

No, there is no serious problem at all, you just need to flash a stock kernel via flashtool (In a stripped FTF or a full FTF) or via fastboot if you have the kernel.elf

You have to flash stock kernel - there are many guys who relock bootloader on custom kernel - xda us full of stories like that..
They have toy now instead of expensive device..

No, it's very easy to fix, just flash a stock kernel after relocking the bootloader, it does not brick the phone relocking in a custom kernel, it just gives you a boot loop which is easily fixable

You cannot update using pccompanion with an unlocked bootloader.
Just flash a stock FT, restore your TA.
Then if you want to upgrade just use pccompanion and root again.
