For locked bootloader only solution is to flash a gb ftf fw first and then flasha ny custom roms
Cheers,

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.

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.

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? If i need stock kernel where can i download?? —Thanks guys

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)??

Yes. Exlude everything except kernel will flash only the kernel.

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 dunno if m postin in the right thread, but can plzz sum1 post the link to the stock ics B.1.54 fw for xperia u for LOCKED bootloader...if i try to flash a fw for unlocked bl and then relock the bl then the phone goes into a bootloop (softbrick) and so i have to reflash the stock B.1.10 fw for locked bl....i have the B.1.54 fw for unlocked bootloader but m nt gettin 1 fr the locked version....plzz dnt say that B.1.54 is nt available fr locked bl as i have seen posts by users wid 1 sch fw
i relock my bootloader by this method relock bootloader post
is there any other option i can try...plzz lemme know
thnxx in adv
If you are using stock. 54 tft file, it doesnt matter if your bootloader is locked, it will work on both. If you want to use Rom for unlocked, then you need to keep bootloader unlocked all the time you are using the Rom. If you flash unlocked and then relock it, you will get bootloop.

If it is Sony stock tft file, then yes, its working on both, locked and unlocked.
If its customized Rom based on stock, then read the OP.

then wt bout this Stock ROM fw 6.1.1.B.1.54 fr xperia u
P.S. branded = locked bl
and unlocked = unlocked bl, right?
There is thanks to brainkafka for kernel, maybe its updated.

Do you have a ST25a or ST25i? If you're installing an ST25a on a i you should exclude the base band in flashtool and the other way around. I don't know if this causes the boot loop, but it might be worth the try.
Yes... But a boot loop isn't necessarily. It's the best probability. Maybe... Just vibrate and nothing else.

Yes you can, my advice is don't unlock, it voids warranty and the only reasonyou would want to is to flash a custom kernel. You can still root and install cmw with a locked bootloader and most Roms are flashable via cmw

Ya u can unlock ur booloader and can still flash stock..
And their nt rish becoz u can still relock ur bootloader when u wish.
