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

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)?

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?

Ok, it's not like I didn't had search how to do it, it's just that so far my search has been very frustrating.
First, my phone has stock rom, v. 12.1.A.1.201 with JB 4.3. And I just want to flash a stock rom (maybe a little tweak to make it smooth and faster) + root.
So I searched (maybe not too good) how to do it, and I found this: to install any rom, you need to have an unlocked bootloader, so far so good, but then when you search on how to unlock it, surprise! you need to be root to backup drm keys ... Ok then, I tried another aproach, maybe flashing from custom recovery, but then again to install a custom recovery you need to be rooted ... back to the begining.
So if anyone can enlighten on how to fulfill my very reasonable request, I would be sooo happy.
No need to unlock bootloader in order to flash stock based ROMs or for rooting. But for flashing custom kernels/ROMs that need a custom kernel, unlocked BL is a must.
There are many guides. Check through this index.
http://forum.xda-developers.com/showthread.php?t=2618222
It's sticky btw
Basically you have to (because you're locked BL),
1. Downgrade to 4.1.2
2. Root with DoomLord method.
3. Install recovery.
4. Flash a pre-rooted 4.3 ROM (.201) through recovery. Flash SuperSU update at the same time. Shutdown phone (NOT reboot).
5. Flash stock 4.3 kernel (.201) via flashtool.
6. Done. On rooted .201. Then install a recovery (because previous recovery got erased with ROM flashing).
#Details in guides. Good one here: http://forum.xda-developers.com/showthread.php?t=2727143
**Optional: Do a TA partition backup and keep it safe. Someday you can unlock the BL
You can follow mrhnet's post that helped me solve my dilemma! You can downgrade your phone, exploit root, flash recovery, flash SuperSU and then backup TA. Once TA backed up, the freedom is finally yours!

Can someone please help me..
I have an Xperia SP currently running 4.1.2 rooted, bootloader locked.
My aim is to upgrade to 4.3.3 and root, for which i will have to unlock the bootloader. To do so I need a TA partition backup , for which again, root is required.
So, my question is that is it okay if I take a TA Backup now [in 4.1.2] and then upgrade OTA and unlock bootloader, root and then restore the 4.1.2 TA backup onto 4.3.3 in order to restore DRM keys and Relock the bootloader?
Has anyone done this?
is it safe?

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
So everything went smooth! Now i'm on 4.4.4 with root and locked bootloader BUT x-reality is not working LMAO. I'll try to install it now.
Edit: yep, it's definitely not working. I relocked bootloader for nothing! haha

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

Hi guys,
I've rooted my Z1, installed CWM and unlocked my bootloader (TA-backup present). Everything seems fine.
Exept for the fact that I cannot find a custom rom with the features i specifically want (as close to stock as possible, without bloatware, but with all the Sony Camera features) and therefore I would like to go back to the original 757 firmware that I had before I rooted my phone,
I do want to keep my CWM recovery, and need root acces (ie SuperSU)
I'm lookin for the Original Sony 4.4.2 757 rom which i can flash through CWM
Can anyone please help me?

Tiemen
Edit: I see that theres a new 4.4.4 firmware. If possible I would like the stock rom for this one.

Certainly you will lose both root access and CWM when you flash
Search 'how to flash by Flash Tools' in your own language
Be warned that you will also all stuffs which are in Internal Memory, like files, messages, photos, movies, etc

Download the 4.4.4 stock firmware (FTF file) and flash via Flashtool. Ensure that you untick the Wipe data option in Flashtool, before you flash. This way, your user data will be intact after the flashing. And yes, you'll need to reroot (can use this tool) and install recovery again.
Thanks for your info!
I will start reading about the flashtool and will try asap.
Lets hope I won't get an expensive paper weight :silly:
If I want to go to full stock again (ie Relock Bootloader and no root), Do I need to flash FTF, then restore TA-partitions and I'm all done? Or do I need to root it before I can restore TA?

You'll need root before you can use the Backup-TA tool to restore. Do read the FAQ of the thread for the tool.
