Hi guys,
I'm kinda desperate right now. I am using 4.3 with 12.1.A.0.266 firmware.
My aim is to install CWM. For this I need an unlocked Bootloader and Root.
But all tutorials I could find are kinda contradicting themselves.
To root I need UB.
To unlock Bootloader in need to Backup TA partition.
And to backup TA partition I need root.
The tools from doomlord all require the old firmware, but silly me has already updated.
Is there any way to unlock Bootloader without root for backuping TA partition OR root with locked bootloader?
Any help is appreciated
Im afraid there isnt any root method for locked bootloader, so You must flash 4.1 using flashtool, root 4.1, backup TA, flash 4.3, unlock BL, root 4.3 and relock BL by restoring TA. The whole process just sounds hard and its complicated but follow those steps and itll be fine
Cheers

When updating to 4.3 I lose root, dont I? So there must be a way to unlock BL with no root? I think then i would lose my Drm keys, thats why i backuped them on 4.1, didn't I? And i surely can use the backup of TA i made in 4.1 for version 4.3?
Thank you for your help already!
Same, Bro

Simply use flashtool to flash a .534 firmware and root using vroot or kingoroot. You dont need to unlock your bootloader to do any of this. Currently .257 firmware is not rootable but there are stock custom roms which are pre-rooted based on .257 firmware.
ps. is your bootloader unlocked or locked?
Locked bootloader.
everything working and rooted gain, learn some new flashtool things.
Thanks

Hi, This is probably a really stupid question but....
I'm currently on .257 with root.
If I backup my TA partition on .257 then flash 14.2.A.0.290 and unlock my bootloader. ( I then plan to root with unlocked bootloader)
Will my TA backup still work if I ever want to lock the bootloader again? (even if it means downgrading to an earlier version to obtain root again?)
Thanks
As far as i know the ta partition (alltough the backup) have no firmware version. So I think it will be possible.

I have .290 on unlocked bootloader with stock kernel and root. Since relocking is only a step away should i do it or will i brick my device or will i have locked bootloader without root.

I tried to restore TA partition (which locks bootloader) and this soft-bricked my device. I solved it flashing stock ftf with flashtool. I have the same question, I want to have root in locked bootloader, in order to have drm, keys and dont loose x-reality, and most important bionz processor.

I backed up TA in 534 and restored in 290, I didn't know it could make problems. Anyway, how could I backup TA in 290? There is no real root for this firmware.

Hello to everyone on Xda! I'm a C6903 user with 4.3 on 14.2.A.1.136,
I have a problem, i want to backup TA before Unlock bootloader, but for backup i need root, there is a possible way to backup without rooting and after unlocking bootloader?
I need this for a trusted unlock! Thank's to all!!
You can't Backup TA without Root and you can't Backup TA after unlock bootloader because after Unlock you will lost your DRM Keys forever with warranty.
You can Root without Unlock Bootloader so there is no problem at all. Use NUT method.

This is the NUT method, you have to downgrade with Flashtool to .534 provided by NUT to not lose IMEI, Root with Bin4ry Applicartion, then follow the instruction to update to .290. When you will have the .290 Rooted then you are ready to Update to .136 with the same method HERE
Watch the Tutorial Video How To.
This is all for Locked Bootlader.
Downgrade to 534. Root & backup ta. Flash stock 136 and unlock bootloader. Then flash stock adv kernel by doomlord. Install Update superSU and busybox. You will have root 136. That's it.

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
