You unlock your bootloader, and then you flash the custom kernel you want.
No need for relocking.Even if you wanted to flash stock kernel, there's no such need.
Check the Ultimate X8 FAQ sticky. There is an explanation for this.

hi all i am having many doubts regarding installing custom rom please help me...
my doubts are
1.Do i need to unlock my boot loader to update my baseband
2.Will the unlocked boot loader stay always so that i can flash many kernel and custom rom or do i need to unlock each time
3.After unlocking which case should i relock my baseband
i am sorry if these questions are very basic i am very much confused
1.No, it is nor required to unlock the bootloader to update the baseband.
2.Yes, it will always stay unlocked even if you restore with PC Companion or SEUS.
3.You should relock it if you are sending the phone for repair at Sony Ericsson.
First check manufacture date before proceding to unlock bootloader.

As said above, check manufacturingdate. IF above 11w29 then dont try to unlock. Chances are youll be ending upp with a brick.

If it is an offical update from SE, that doesn't need to unlock.
If it is kernel, rom bla bla bla from this FORUM, Mostly rom will need you to use the kernel, thus it is a must to unlock the bootloader.
So, if you're using original eclair, planning update it, there's is no risk except for electrical trip suddenly happen

if you're not unlock your BL, you can not flash your kernel.. so u can brick your phone..
use C1 tool or flashhtool to check it man..
Hi guys,
I unlocked the bootloader of my C5302 using fastboot and rooted it successfully.
Now I'm trying to relock the bootloader following these instructions but, after relocking, the phone is unable to boot.
Note that when I unlock again the bootloader (still using Flashtool) the phone can start without any problem.
I saw that a stock kernel is needed to relock bootloader so I installed this kernel but I still have the problem.
Anyone has an idea ?
Thanks by advance

That's not stock anymore since its been rooted and modded a little. But I haven't tried locking BL ever, so wouldn't know. However, try flashing kernel.sin from the ftf and then try relocking
Didn't work either.
Do you where I can find stock kernel ?
you'll find stock kernels here: http://forum.xda-developers.com/showthread.php?t=2405933

Below are the stock kernels, giving 2 one is for .257's stock firmware and other of 2.245's hope you can relock your bootloader and can boot into your phone

Hello everyone,
I just bought Xperia Z1 and I'm running 4.3 and would like to unlock my bootloader. Since I never did it before I still need to backup my TA first. Since this needs root I'm stuck in a loop: Backup TA needs root to work but root on 4.3 needs an unlocked bootloader to install cwm to install SuperSU...so anyone can help me how to do this?
To root the last 4.3 you don't have to necessarily Unlock Bootlader, just follow the instructions on this page, post #16
http://forum.xda-developers.com/showthread.php?t=2588331&page=2
After do that you can Backup TA and Unlock Bootlader but you have to UB only if you want flash Custom Roms with Custom kernels. To flash Custom Roms with Stock kernels or root your phone it's not necessary to unlock it.

okaay so i rooted my phone again and decided to unlock my bootloader, i have verified that i am able to unlock my bootloader and follow all the instructions on the official sony website on how to unlock the bootloader. i get no errors during the cmd process either, i turn my phone on and it gets to the purple boot animation screen and then freezes. Is there anyway around this ?
EDIT: Also i used DooMlords thread and get the same problem? /: - I also use Flashtool but when i press 'blu' i only have the option to RELOCK my bootloader? :S
Anyone ? /: been looking for the solution all day

Just flash any desired custom form via fastboot and that's all, it should work.
When I unlocked my bootloader with stock firmware it doesn't boot anymore either, so I had to flash any other or reflash it again

Just flash a official FTF, then go to service menu, tests -> configuration and if your bootloader status is:
Unlock allowed: Yes - you can unlock your bootloader
Unlock allowed: No - your bootloader is hard bricked and there's no way to solve this (permanently)
Unlocked - congratulations.
I suppose your bootloader is hardlocked. check for yourself and if anything changes - quote

If you are on a custom rom you just have to flash the custom kernel over it putting the phone in fastboot . No need to unlock bootloader again. Please ensure that the rom supports the custom kernel or there can be bootloops .

I have tried unlocking it with and without a custom ROM on my phone, it says 'Bootloader Unlocked: Yes' on the service info and i also only have the option to RELOCK my bootloader when i try it on the flash tool. Does this mean that it may actually be unlocked already?
EDIT: im also using This custom ROM which has custom kernals to select from
-Thanks

The rom that you gave link to is a stock firmware based custom rom, so it will have stock kernel.
I think it must be written Bootloader unlock allowed: Yes, on your phone
You will need to unlock the bootloader, PM me I will guide you how to do it.
