To install this ROM you will need to have an unlocked bootloader
You have unlocked bootloader you do not have a locked bootloader as this device does not have a locked bootloader for you to unlock.

[SOLVED]Custom ROM or Stock ROM for unlocking Bootloader?

Hello everyone!
I have GinderDx v028b and i am on stock kernel.
i want to unlock my bootloader and i searched the forum but couldnt find any reference for
unlocking bootloader using the GinderDx ROM.
So should i install the stock rom first or can i do it using ginderdx only?
And the manufacturing code behind the cell case is 11W26.
Its safer to go back to 2.1 And then proceed with the bootloader unlock process
Sent from my X8 using xda premium
yes, it is safer to go to eclair, but i unlocked mine BL on gingerdx. i personally think that it doesn't matter because the script unlocks the BL when the phone is booting and the OS isn't running yet (but i can be wrong )
Thanks a lot guys for helping!! :good:
Successfully unlocked my bootloader!!
Did it from the stock rom
I envy you

You can do this.
OR a much easier method is to Unlock the Bootloader and use DoomLord's method with his kernel. I used the method in Post #3: http://forum.xda-developers.com/showthread.php?t=2129121
He said without unlocking the bootloader

What?
Is your bootloader unlocked or locked?
I'm not sure bootloader is unlocked or locked, I dont want to unlock if it is locked, is there a way to root without unlocking bootloader?
Sent from my LT30p using xda app-developers app
If you are unsure them it is locked, because you have to unlock it yourself.
Yes you can root without unlocking, follow the instructions I gave above

Yiou are kidding right....did you do any reading...
Please read the all in one thread. Its the first thread in the Q&A section. It gives all the info you need on unlocking our bootloader.
But first,
goto the dialer and press
*#*#7378423#*#*
goto service info/configuration
If the bottom line says
bootloader unlocked allowed: No
You cannot currently unlock your bootloader by any known means
If it says
bootloader unlock allowed :Yes
Then read the all in one thread and follow the instructions
It says bootloader unlock yes, I tried doing I couldn't do it

You are not following the instructions properly then, and unless you give more details in how and at what step it fails I can't be of much more use

Hi everyone, please I really need help on how to root xperia t, I was using Samsung galaxy s2 and rooting it was so easy but xperia t is a Little bit confusing for me. I am a novice with sony xperia t. I have already unlocked the bootloader, but for rooting, I need a video tutorial or step by step manual on how to do this, because I need to do it. I have so many programs that require root Access, without root is all useless. thank you very much beautiful people and hoping to hear from you....bye

wow,
why have you unlocked your bootloader? What did you want to do?
Anyway, now that you have unlocked there is no need to root, just flash a custom kernel (I recommend DooMKerneL, find it in the dev section, make sure you get the one for the T)
Once you have flashed that you will have root.

Yes it is, just flash an ICS ftf

EDIT,
Sorry my mistake, now I am at my PC I can see you have a V.
In which case rooting is easy..just unlock you rbootloader and flash an insecure kernel.

There does not appear to be a method for locked bootloader.

(Q) how to check BOOTLOADER

Hey guys
I just want to ask you something about xperia sp because im going to buy this tomorrow (excited)
Guys how can i check the xperia sp if it BOOTLOADER LOCK or UNLOCKED?
and what is the advantage between LOCK and UNLOCKED BOOTLOADER ?
Sent from my GT-I8190 using xda app-developers app
Type this into dialer *#*#7378423#*#* go to service menu/configuration
If it says boot loader allowed YES you can unlock which will let you use custom kernels.
If it says boot loader allowed NO
then you can't unlock which means no custom kernels which may also mean custom ROMs maybe limited.
