From my experience relocking does not erase the data only unlocking.

its not important if your device is rooted or not. (relocking)
but you should know that you have to use a stock kernel when your bootloader is locked!

re-locking doesn't wipe anything!
just unlocking will erase data partition.
Ok thanks, im on stock ics using advanced kernel (ics11.elf) for using cwm—recovery, so now how do i gain ics stock kernel after i relock?will relock automatically put me back to stock kernel or will i have to flash stock kernel separately before/after relock?

you can:
1) flash stock kernel with flash tool( select your ftf 4.0.4 rom & use exclude option)
2) re-lock bootloader
its not important when u flash the kernel! but the device with custom kernel & lock bootloader cant boot.
So by using flash tool on stock ics rom ftf will surely give me the options to only flash (kernel) without flashing the hole ftf rom by selecting (exclude)??

Relocking bootloader requires stock kernel. Kernel is included in a ftf file. The complete stock firmware is in ftf file, which you need to install via Flashtool.

Please post your question in Q&A therad
I made it with this way. You must not downgrade, just change kernel with flashtool. Flash 4.0.3 kernel, root and install cwm, then flash back 4.0.4 kernel.
To flash kernel, you have to unlock your BL first.
BUT, in fact, you could flash a pre-rooted kernel after unlock BL, so you needn't flash a 4.0.3 kernel first

Unlock your bootloader to flash custom kernel. In this rooting method you flash sony stock kernel, so you don't need unlock your bootloader.
yes you don't have to unlock your bootloader to flash the "stock" kernel which is an "ftf" file... just flash your 4.0.4 normally, after flash the 4.0.3 kernel, when is done reboot and root it, and reflash the 4.0.4 kernel... voilà... and after you can install your CWM

Please post questions in the Q&A thread. Thank you.
My Xperia S is unlocked bootloader, using [email protected] rom with ICS15 kernel with CWM recovery. If I want to re-lock bootloader what steps needed to flash stock ICS rom. I mean, do I flash stock rom first and than re-lock BL or otherwise. I am asking this because the rom I am using is for unlocked BL therefore when I re-lock the BL there will be conflict which will force the phone to stop working. The kernel I am using will work with stock rom? If someone guide me how to start the process with step-by-step guide. Thanks

Hi monivan. Sorry for my ignorance. The kernel I am using (ICS15) is not stock? If no, from where I get stock kernel and how do I flash it. CWM or Flashtool.
if you have a ftf for stock ics, extract the ftf using winrar or 7zip then look for kernel.sin, flash it via fastboot, or you can flash via flashtool, uncheck everything except kernel.

i think u need GB kernel first
For locked bootloader only solution is to flash a gb ftf fw first and then flasha ny custom roms
Cheers,
AJ
Flash Gb.ftf file via Flashtool, it's easy
Sent from my Xperia Mini Pro using xda app-developers app
Well this solution worked for me some months back when I had locked bootloader.
Your on a ics rom. Download any gb rom of ur choice
Go to cwm full wipes then install gb rom and dont reboot just power of device since rebooting will end phone in a loop. Since ics kernel (stock) and gb rom
Then connect to pc via flashmode (since fastboot is for unlocked bootloader device)
Flash stock gb kernel via flashmode in flashtool. Done! No need to flash stock gb and root it!
P.S. Flashing kernel is recommended before flashing rom but its jst a short technique to avoid flashing stock ftf and re-root it.

flashing a FTF will remove the custom recovery and root but not lock the bootloader, but you can lock it with flashtool or by restoring the TA bckup

So that means I don't need to unlock the phone to flash FTF?
