Some phones are not allowed to unlock, you can check by dialing *#*#7378423#*#* and go to Service info ------> Configuration, and check if the unlock for bootloader is allowed or not, if it says no, then you can't, if it says yes then we can go to next step.
I already checked and it is allowed
boot-loader

1.Download the Flashtool and then install it on your computer.
– get it from official Flashtool Download page.
2.Launch the Flashtool program on your computer after the installation is complete.
3.Click the ‘BLU’ icon in Flashtool.
4.You will now be asked to connect the Xperia Z2 in Flashmode.
5.Power off the phone.
6.Connect the USB cable to your PC first, then press and hold Volume Down on your smartphone and connect it to your PC.
– Flashmode should be loaded and Flashtool will show the Device Selector screen.
7.Select your Sony Xperia Z2 model from the list.
8.Now Flashtool will display the ‘Bootloader Unlock Wizard’ screen.
9.Click on the Unlock Button for the Bootloader Unlock process to begin.
10.After the process is complete you will see the Flashtool log window. Check the log info and verify that the Bootloader Unlock process has been applied successfully.
I think you should open flashtool software with a working internet connection so that it can synch device list from GitHub.

It's better to do it via Flashtool i Think...The procedure is this:
1. Download Flashtool,then install,then go to C:/Flashtool/drivers and install flashtool_drivers,when you've done this if your pc has a 32bit cpu,start the normal one,otherwise start Flashtool64
2. Before connecting the phone to the pc,enable USB Debugging and Unknown Sources,then connect the phone and let it install the drivers.
3. Go to FlashTool and when it recognizes your phone,click on Plugins->Bootloader Unlock->Run and follow CAREFULLY the instructions.
4. When done,voilà,you phone will have unlocked BL! But don't forget to root it
Hope I helped ya

Yes, if you unlock the bootloader and flash a custom kernel it's automatically rooted.

http://droid-maniac-milan.blogspot.in/2012/04/how-to-unlock-bootloader-in-xperia.html
the below is copied from the link i gave you.
FOR XPERIA X10/ X8/ PRO/ X10 MINI ONLY
Before unlocking bootloader you should check whether it is safe to unlock or not.
For that:
1. download s1tool >>you can download it HERE<<
2. Run the downloaded program and click "identify" button on top right corner.(Don't connect your device)
3. Now switch off your device and connect to PC pressing and holding back button in your device.
4. If it says "SEMC SIMLOCK CERTIFICATE", then you can proceed further for unlocking bootloader.
#NOTE: Proceed only if your device passes the above requirement.
Steps to unlock bootloader in your device
1. Download flash-tool V0.6.8.0 >>you can get it HERE<< and run
turn on your USB debugging on device [setting>applications>development>usb debuging]
2. Connect you device and wait until it recognizes your device
3. Then click "plugin > bootloader unlock> run"
4. Then you will get a message in which says "to switch off your device and connect to PC pressing and holding back button in your device" and do it.
5. The unlocking process will begin. Wait until Flashtool ask you to disconnect the cable off
the phone, then turn on the device and connect the usb cable once again
6. Then flash tool says ”Successfully applied unlock Rebooting”
7. Then your bootloader is unlocked
Now to check whether bootloader is unlocked or not
2. Run s1tool and click "identify" button on top right corner.(Don't connect your device)
3. Now switch off your device and connect to PC pressing and holding back button in your device.
4. Then under "PLEASE ATTACH TURNED OFF PHONE NOW" this line
we can see: RUNNING S1_EROM VER "r8A033" , in which "r" should be in small letter now
5. This says you have unlocked bootloader
i installed custom rom xperia S. unlocked bootloader and works fine for me..no other issues...
http://forum.xda-developers.com/showthread.php?t=1516960
but now i am stuck in a new trouble...i re locked the bootloader..i dont knw why on earth i did that..waiting for the help of experts here)
Thanks. It's unlocked now. Now I want to flash wolf's rom. Do I need to flash kernel also
I am assuming your phone can be bootloader unlocked and you have unlocking key from sony.
If you don't know then refer to this post http://forum.xda-developers.com/showthread.php?t=1527159

yes, turn off your phone then connect USB while pressing specific key.
same applies for fastboot method
When I am installing drivers, I am getting "don't install or install anyway", I choose install anyway but the same window comes up again. Should my phone be turned on, off or in flashmode or something?

Yes I checked, it can be unlocked
If you have installed Flashtools and its drivers correct you shouldn't get any driver prompts when plugging the phone in
Assuming you did a default install browse to C:\Flashtool\drivers and execute the drivers file. Make sure you select the drivers for you phone ie "Xperia U" and scroll to the bottom of the list and select Flashboot and Fastboot drivers. From what I have seen so far most people are not installing these 3 drivers.
karimkahale: I would go back to the Sony website and get your unlock code again. Maybe you entered some wrong details...
Please help me out,
when I am trying to install fastboot drivers from flashtools drivers folder, I am getting an error saying driver installation failed.
My os is windows 8 pro 64bit..My phone Xperia U (ICS)

Thank you for this tutorial mate!
It's better if we can get unlock key from flashtool

Thanks a million, but would my warranty be void immediately after I unlock the bootloader, what's the regulation about this matter, I'd like to keep my warranty.
---------- Post added at 10:00 AM ---------- Previous post was at 09:45 AM ----------
If i relocked the boot loader the warranty wouldn't be void, right?
Not quite;
It all depends on your repairman...
The standard, though, is, that the warranty is valid if the guys at the repair center can flash a stock ROM (.ftf) onto the phone. Some phones can do this without their bootloader being locked, but some can't do this after their bootloaders are unlocked, even if they are locked back afterwards...
Now, I have a question:
I'm having the same error as karimkahale...
Whatever I do, I get that stupid error, and not even Sony can help me (their support team (that needs a week to reply to a simple e-mail) said that thy don't know how to help)...!
Thanks a lot for the guide, it was really helpful!
Cheers!

Start S1Tool, press the identify button and follow the instructions.
If you have SEMC Simlock Certificate (shown at the bottom) you'll be ok.
Start Flashtool, connect your phone with usb-debugging turned on and choose Unlock Bootloader from the plugins-menu. Follow the instructions.

Do some searching, S1Tool and Flashtool are tools that run on your computer, it's just a matter of connecting your phone with your usb-cable and pressing a few buttons. Actually unlocking the bootloader won't take a minute.

It depends on how fast you can download and install the tools you need. Once you've installed them you can be done in 10 minutes. You've already got flashtool, so that's one less concern.

Your phone was rooted wasn't it? If it's stuck, abort the process and press the root-button (padlock) in flashtool, to root and install busybox to your device. Although aborting a process like this might brick your phone, i don't think any changes to the actual bootloader were already made, but don't blame me if your phone gets bricked.

hmm that sounds crazy. idk how this could be.....
but what you can do is:
1. download sony pc companion software & reset, repair or update the phone if avaiable.
=> if still bootloader unlock allowed: NO then:
2. download & install flashtool. after iit install install its drivers from flashtool/drivers folder (need your phone driver + fastboot + flash driver) optional: install android SDK. (just leave all it is & press install packages.) if you done, flash a stockICS.ftf (<= firmware) like shown on this page: http://talk.sonymobile.com/t5/Android-development/GUIDE-How-to-Install-Jelly-Bean-ICS-Ice-Cream-Sandwich-and/td-p/154389 (you can download the firmware there, just make sure you choose your model right. use ICS .587) (boot once)
now look if bootloader unlock allowed....
if still : NO, then maybe ask your carrier where u get this phone. normally if your contract is end, they unlock your device for free (its here like that.)
you can also try just to request a code from sony site & try to unlock it maybe you are lucky. (you said you was allowed on pre version)
good luck!!!
the thing is if your bootloader locked = no cutom kernels = NO JB or KK rom for you. only stock based custom roms for locked bl...
