OK.. So first of all backup you ta (Ta controls your bravia engine) here is thread http://forum.xda-developers.com/showthread.php?t=2292598 unlock bootloader with fashtool (fashtool is easiest way) To relock just restore Ta (remember not to restore it on custom rom) that all.... And if you don't know.. you don't need to unlock bootloader to flash stock rom...

Hi I recently bought the sony ericsson WT19i (Live), now I want to flash cyanogenmod but i don't know how. I read something about unlocking bootloader bu I can only find tutorials for Xperia range phone's also is there a way to backup my current ROM and EFS partition?.
I have alot of expirience with android so just some links should do.
Also is there a way to Re-Lock the bootloader?
You must unlock bootloader first. Then flash custom rom, and install cm using update zip.

Thanks but unlocking avoids warranty and no official updates. Is it worth it?
From what i understand with a locked bootloader you cant boot into recovery, right?

Ssory my english is bad. I am russian user.
With unlocked bootloder you can not oficially update you device.
You can install cwm to locked stok rom and boot into recovery.
Unlock bootloader only need to flash modded kernel.
after unlocking you can lock bootloader. Drm key's not restore

Yes, i believe it's possible with the latest version of flashtool (+ update).
The safest way though, is to revert to stock (do a backup of your current rom&setup of course) then perform the unlock.

Alright alright.
But,if i backup my current rom (which is for LB) then unlock my BL and then restore my backup of my LB Rom,i will have a Rom for LB on my phone with ULBL.

yes dude, you can relock your bootloader but your DRM was lost forever
relock your bootloader by flash relock bootloader.ftf with flashtool
Hi,
I am new in rooting android. Let me explain you all my issues in detail as I've been searching for long but didn't got any info regarding my case.
Scene:::
I never rooted my Xperia neo v.
I updated to Official ICS latest firmware. My neo was running fine for about 4 to 5 months (except it was laggy).
Recently, When I turned on the bluetooth , it got stuck in bootloop . So, searched and from the great developers help in this forum, I got the solution to Falsh my neo v with stock rom . I did and now I've 4.0.2.A.0.62.
Now,My questions are:::
Q1. Can I root my Neo V without unlocking the bootloader ?
Q2. I tried the Fastboot method but Android SDK Manager doesn't run on my Windows 8 64bit, tried to fix it too but it didn't fix. So any alternate solution to this method?
Q3. Also, When I check via *#*#7378423#*#*, it says 'Bootloader unlock allowed: Yes'.Does it mean I've an Unloackedbootloader?
And it might sound a lil stupid, But Please can I have the detail rooting solution according to my above questions?
Thanks all,
Akash
First of all there's no connection in rooting and bootloader.
Rooting is simply giving super user capabilities or allowing root acess,like admin rights in windows.which stock android os don't provide for security reasons.
If your bootloader is locked you can't install other kernels accept the default sony provided kernels,but you can root,install other custom roms like ihave zellycream v2.meanwhile in unlocked bootloader you can flash with custom kernel of your choice.
The message ur getting means you have a locked bootloader, which can b unlocked.to unlocking there are several methods..you can get by searching the forum.
About me I have a locked bootloader. And on zellycream v2 rom.

Hello all hope somebody will give me proper guidance and links of threads.
Just got my Xperia ultra today it is United Kingdom (GB) model number C6833 with Build number 14.2.A.0.290
I am very new to Sony Xperia phones, have bit experience in rooting HTC, Archos, Samsung but Xperia is new to me.
I did some research and found it is only possible to root 290 firmware with Unlocked bootloader. Here is the problem start I don't want to loose my DRM keys by unlocking bootloader, wanted to have backup of TA partition before I unlock my bootloader if I needed in case. I can't backup without Root so I am stuck and confused what to do? Is it possible to downgrade to other firmware to root my Xperia ultra then I can backup my DRM keys. Also found some posts by users saying if you downgrade from 290 you loose IMEI so is there any solution?
your help and guidance will be highly appreciated.

Follow the top sticky in this section.
Imei isn't a problem if you go back to 290 ftf, and even if you don't there are solutions.

You can revert back and will probably loose imei. But you will still be able to root and backup your TA that is intact. And from there use any ROM you want.

what about if I wanted to use stock but rooted, rather then flashing any custom rom?
