Hello guys... Read this guide to see how to run Stock JB rooted with a locked BL device.
Unfortunately this method don't work on devices that can have their bootloader locked, this method is intended to be used for who CAN unlock his bootloader but for any reason want keep your bootloader locked.
What you're going to do is basically:
1- Unlock your device.
2- Root your device while is unlocked.
3- Relock your device and your device will keep rooted.
Question: But, when I unlock my device don't I lose my warranty and DRM keys forever (so Bravia Engine, Music download info won't work correctly)?
Answer: Yes, but this method involves to backup your TA partition [Trim Area] before you unlock it, after you will restore your TA partition and this will return your bootloader to locked status, remove unlock code key and bring your DRM keys back.
Attention! This method will work only if you have a bootloader unlockable device, but you will keep your phone rooted after you relock bootloader.

I tested this on my own Xperia S (LT26i), if you have an Xperia SL and Xperia ion this will probably work. I don't know about Xperia acro S because @DevShaft Backup-TA tool isn't confirmed if it's working on Xperia acro S (only Xperia S, SL and ion users confirmed it's working).
UPDATE 1!
@DooMLoRD is working on a Pre-Rooted ROM for LB/UB, also he's working on a CWM for LB, it's an easier way to root but requires a clean install.

Did you let the phone reboot on the steps I said was optional (maybe not optional afterall).
I did all steps and worked twice and worked.

Only if you flash someone's else TA or if you restore the TA of some device that isn't confirmed as supported.
@DevShaft 's Tool have a lot of security features to prevent the TA corruption or a fail restore.

It's true that DevShaft's tool is very thorough, but fact remains that messing with the TA partition in any way is very risky.

I WOULD HIGHLY RECOMMEND TO NOT MESS AROUND WITH TA
You are misleading people. Change Topic.. It's not Root for locked BL, but it's method to root with relocking BL. It's not same.

STEPS TO UNLOCK BOOTLOADER

3) Now Get the UNLOCK KEY FROM SONY from HERE
4 ) After u have verified that u can unlock bootloader, scroll to the bottom of the page and click "Continue"
you will get numerous prompts, read all info and if u agree click on "Accept"/"OK"/"Proceed"
finally u will get a "Create Unlock request" page, enter your IMEI (sometimes the last digit needs to be removed for this to work), name and email address

6) Hold SHIFT and right click on the background of the folder Select 'Open command window here'
7) Connect your phone in fastboot mode (turn phone off, hold Volume UP button and plug in USB Cable) [make sure drivers are installed as explained above)
8) In the cmd windows type in fastboot.exe -i 0x0fce getvar version
If a value is returned (it will return 0.5), it means the phone is correctly connected

:good:
good job bro!
I just wanted to ask if we could unock the bootloader using flashtool so there's no chance of voiding warranty. As backing up TA would save DRM keys.
Yes u can unlock it using flashtool. I am windows 8 so i find unlocking with fastboot is easier and it just just cause 6 mb of data.

Well I tried with flashtool it denied unlocking :silly:
I think it would be better to go with the official unlocking.
Thanks.
u should add the TA Backup guide also

You need to restore the stock boot partition because restoring TA partition will relock the device or else you will soft-brick it. If you have a dump of it you can restore it before restoring TA partition, otherwise you need to reflash with flashtool or SUS.
This is what I learnt from other Xperia devices in general.

Can you still use SEUS when you have unlocked the bootloader to restore the original firmware prior to re-locking bootloader?
I thought it would be via flashtool only, because as soon as you unlock the bootloader you lose access to PC companion and SEUS.
The reason I ask is I have an XPERIA X10i and you can use anything at any time and it doesn't care.(brilliant olde device)
With my XPERIA S, I only have flashtool, as SEUS and PC Companion (and Sony OTA upgrade) are 'lost' after the bootloader is unlocked.

Really? PC Companion can recognize my Xperia M. Haven't tried SUS restore but it should work, shouldn't it? FOTA updates are known to brick unlocked Xperia devices so I strongly advice you not to try it.
But anyway if you've already restored the TA partition you already have a locked bootloader

PC companion still can recognize your phone even you've unlocked your bootloader, but updating your phone with SUS / PCC will surely brick your phone.
The only way to restore to the original firmware is using Flashtool or EMMA :fingers-crossed:

I dont think Pc companion will brick your phone! I never heard of this things and yes updating through FOTA can definitely brick your phone. Although i recommend not to unlock bootloader unless you are an advance user or a developer.
Sony xperia M gives very good performance over stock so noo need of scripts and other stuff, and i hope someone will develop CWM for locked bootloader too.

I have NOT backed up my DRM keys.. and I have an unlocked bootloader...
I connected my XM SS to Sony PCC..
It did recognize my phone.. However it did not update it stating that I am using a modified software..
Flashtool (EMMA) also recognized my phone.. but dint allow me to update my phone..
And my phone is not BRICKED..
Can you be more descriptive on the exact instructions on how you can relock XM whose DRM keys are not backed up?
Has anyone tried this?
Please quote and reply and share the method if you have tried this on a C1904 XM SS and if it is working !!!!
Thanks
I have a question...
How will I be able to backup my TA partition if root is required? I have not yet rooted my phone. I only rely on official procedures because I have bricked my two other phones previously. Have you had root installed on your phone when backing up TA partition?

HI guys, i am interested into installing CM11 on my Xperia S , and i have backed up my TA and stored them on my PC.This procedure though, requires unlocked bootloader. In case i want to revert my phone back to locked( stock ) status, what do i have to do? I mean, how will i flash this TA backup? in a locked or an unlocked status? and via fastboot with Flashtool?

You save your TA via? Flashtool or some script? Use the same program as you use to backup. If ftool - probably flash it via ft.

Before i flash the restore file i have to be on stock Sony Fireware? And what must my bootlader status be like? Locked or unlocked?
Best idea its be on stock.

The answer is
1. to backup the ta you need a tool called backup TA from the cross development section
2. you don't need to unlock ti backup ta
3. You must be rooted to backup the ta partitions

Hi everyone,
I have my TA partition backed up.
I've read somewhere here that if I restore TA partition it would also relock the bootloader.
Is that true?
I want to restore my TA partition, relock the bootloader, then flash a ftf (Customized USA 14.5.A.0.242 / R2D ) from XperiFirm. I would also be following this guide
http://www.xperiablog.net/2015/03/1...xperia-lollipop-using-xperifirm-and-flashtool
Click to expand...
Click to collapse
Should I restore my TA, then relock bootloader, then flash ftf?
Or I can just restore TA (that would also relock the bootloader as a i was asking above), then flash ftf?
Also, I'm on XZDualRecovery, would I lose it (which I would actually want to do) when I restore my TA? or if I flash a ftf?
Basically what I'm looking on here is to restore my phone like it was just bough from a store but with the latest stock ftf.
Thanks

- relocking the bootloader does not restore your TA
- but restoring the TA partition relocks the bootloader
- by flashing a ftf you will loose your custom recovery
to restore a phone like you bought it just do the following steps:
1. restore the TA partition
2. flash a .ftf official from Sony with flashtool
3.reboot
and you are done
