Hi everyone!
After searching for rooting newest firmware of 12.1.A.0.266 with LB, I found that it may be impossible without unlocking my BL. So I decided to unlock BL & root it via DooMLord's method and relock again. But I have a few questions.
I heard it's important to backup my TA partition before unlocking so I do a search for it. So I found that root permission is needed for backup TA. Since firmware 12.1.A.0.266 cannot be rooted, I have to downgrade to Android 4.1 and root it by DooMLord's method. It's all OK for me.
But I need to know, if I do restore my TA backup that taken while running Android 4.1, on my newest firmware 12.1.A.0.266, can it be conflicted that lasting bootloop or bricking my device? And relocking my device will it definitely lock my BL to factory status? Please be kind to help me with these questions. :good:
Thank you all :laugh:

No restoring TA wont cause bootloop but to be extra sure you can first flash 4.1.2 restore TA and flash 4.3..

My friend,
Thanks for helping me! :good:
If I restore TA mean I'm relocking my BL. So if I flashed 4.3 again I cannot gain root access coz it cannot root without unlocked BL. Am I correct?
So how can I root 4.3, if I flash 4.3 over 4.1.2 as root is lost after flashing a new firmware.
Thank & Regards! :good:
You need to root on 4.1.2, install CWM. Download and flash a 4.3 ROM and last flash 2.266 kernel
But there are proper threads for this xD

Yes brother..... I see several threads that explaining how to do that. But I wanted to root official firmware by unlocking BL.
If I restore TA, should I relock BL after that or, first relock BL then restore TA?
Thanks!

To make it easy, unlock using flashtool. It'll automatically make a TA backup. Later when you're done flashing stock kernel you can easily click relock and it'll restore TA and relock it for you as easy as 123.

Bro,
Is that unlocking BL via Flashtool exactly same as unlocking via official Sony method? If I unlocked BL besides official method, can I relock it again successfully? And so, since official method needs to device connected with Fastboot mode, but Flachtool needs device connected via Flashmode to Unlock/Relock BL. Why is the different with this methods? Pls kindly explain this......
Thanks! :good:

Yess absolutely the same. I'm not sure about relocking it after using the official method but I think restoring the TA key actually means relocking it. Well actually you will need to fastboot on flashtool right after the flashmode. There is no difference in result. It's just an alternative way to unlock and relock. Unlocking using official Sony method is the old way of unlocking. Flashtool is just to make it easier and simpler. The result will be the same. But be sure that you make the TA backup before unlocking it for the worst case scenario not to be able to relock it

Android 4.3 Stock .266
ROOTED Locked bootloader
So I want to unlock my phone Bootloader and install a fresh AOSP 4.4
Mine current android version is 4.3 Jellybean ( 9.2.A.1.199) and on the sony bootloader unlock site when I insert the dial number it says "Root status ...... Allowed "
I rooted it today ( havent installed recovery buy I can do it later)
My questions :
Can my phone brick while trying to unlock the bootloader?
Do I need to download the latest version or the 4.1 version of android ?
All this I'm doing 'cus my 1 year warrantly has ended today so Why not ? :good:
Don't think the bootloader unlock procedure has much risk of bricking your phone... especially if you use the official Sony Bootloader Unlock method. But you may want to read up on backing up your TA before unlocking the bootloader.

I'd also suggest backing up your TA first. It's all in here: http://forum.xda-developers.com/showthread.php?t=2292598
If you unlock your bootloader, you lose your Bravia Engine. You can get it back when you lock bootloader, but only if you restore your TA. If you don't have this backup, BE is most likely lost forever.

I've done backing up my TA keys ( done the dry restore to make sure )
So Now I only need to unlock my bootloader ?
Still one question :
Can I use my current version of android 4.3
EDIT : Unlocked the bootloader , put rom , gapps , wipped WORKING AS A CHARM
Thanks for the help !
And if I would like to restore to stock do I need to relock the bootloader ?

Nice!
If you want to get your phone back to stock, just flash a stock FTF. Flashtool does not require the bootloader to be relocked for that.
Unless you mean "stock" for warranty purposes, or selling the phone... then I guess I'd say yes to relocking the bootloader, after flashing a stock FTF (and also restoring the TA, of course)
Thanks 4 The Info )))
I used to own an Xperai Sola. Before unlocking the bootloader I didn't know that I had to backup the DRM keys so that I can get back the "Bravia Engine" and "Download music Info option for Walkman" after the bootloader was unlocked. The information that we can backup our DRM keys came 6 months after I unlocked my bootloader.
These are my questions:
On Moto G 2nd gen do we need to backup something similar like the DRM keys of Xperia Sola?
What function do we lose when we unlock the bootloader other than Warranty? Does OS/Android update still work?
Does re-locking bootloader takes the phone back to its previous unlocked state?

2. You can update phone after unlocking bl if you don't make changes to OS i.e. Xposed etc.
If you update even you have made changes to OS your phone will go into Bootloop
3. Yes Re locking and flashing stock firmware takes it to locked state
@NWKENT can answer this Questions more clearly
I´m also with similar doubts. I came from Samsung-way of unlocking bootloader.
Just to ensure if get it right, If I just put root on device, I still be able to update original rom from Motorola ?
It´s a pity we can change anything with xposed (in order to keep upgradable), bcos it´s small things we get used to, and we miss on stock roms...
Thanks,

Thanks for your input.
Please @NWKENT @Falcon G @vinaybaboo can you kindly answer this question?
I guess if you wipe data and unnistall xposed and then flash stock recovery, you will be able to flash via OTA. No need to unroot

1. No you don't need any DRM keys
2. U lose nothing rather than your warranty. Ota works if you don't install custom recovery and change the kernel
3. The new locked state is different than the OEM locked one

Falcon G, thanks a lot for replying.
If the new locked state is different than the OEM locked one, then if a user wants to unlock the phone a second time, does he follow the same method he used to unlock the first time?
So, once the phone has been unlocked it is not possible to lock the phone to back to its OEM locked state?

Long time ago i saw a thread that a user was telling that he wasn't able to unlock the bootloader when he has using certain ftf files. It is pretty strange actually.
Try to downgrade your phone, maybe installing kk and try again mate.
Maybe this will help if you already don't know it. Take a look here. Way old that thread but maybe still guilty.

Post #2 says you have to be on stock kernel to relock your bootloader.
