[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

[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.

i don't recommend you to unlock bootloader as there's many steps to do which takes time.
so you will just need to downgrade to 4.2.2 firmware by flashing the ftf,then root it & install custom recovery,after that flash a pre-rooted 4.3 rom.

too late. i already unlocked my bootloader. but after i unlocked it, my phone on bootloop but i managed to enter cwm. the 'free xperia' and 'xperia' logo keeps coming out if i try to boot my phone. looks like im on a wrong firmware to unlock my bootloader.
now im downloading (C5502) 10.4.B.0.569 tft files and flash it via flashtool, then im gonna try to again if my phone will boot or not.

@Ben Ling
I am new this rooting to. And I want to install a custom rom on my Xperia ZR. How do I downgrade to the previous ROM? Do I just use the flash tool? Is it necessary to backup my TA partition during this process or can I do it when I am about to root the device?Thanks!

download the 4.2.2 ftf,flash it then root it & install recovery
then flash custom rom (only based on 4.3 & stock firmware)

Thank you
So basically these are the steps which I need to perform
1)Download and run flash tool
2)Download the correct ftf and flash it via flash tool
3)Root the phone using doomlord's vroot kit
4)Backup the TA partition
5)Unlock the bootloader
6)Install custom rom
Please confirm if these are the steps to be followed
Thanks!

If you only want root you dont need to unlock bootloader and backup TA.

I live in India so would there be an India specific rom(Stock) for my phone?

@Ben Ling I rooted my zr by flashing 4.1.2 . I have also backed up the TA partition. Can you please suggest any good ROMS now? What should I choose stock based ROMS or AOSP roms like Carbon?
Also, If I want to come back to stock ROM(4.3) again what should I do?
Thanks!

if you want 4.4,then just try the carbon rom
for 4.3,try this.. http://forum.xda-developers.com/showthread.php?t=2726463
for back to stock,you will just need to backup your current 4.3 rom,then if you want to restore,just restore
but the backup will only restore by using the same recovery that you backup.

@Ben Ling Thankyou! One more question before I installed the 4.3 ROM which you mentioned, do I need to unclock the bootloader to install the ROM?

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

Yes you can restore it on any stock ROM you want. Just make sure everything is stock.
