[Q] Re-lock bootloader xperia t lt30p

Hi, I unlocked the bootloader on my xperia t lt30p one time with intention to root it and install custom roms but never did as I nearly bricked it when putting a kernel on. I managed to put what I think is a stock kernel and rom back on, but I went to update it the other day and pc companion says that it could not complete the operation because the phone has been modified. I read somewhere that having the bootloader unlocked can cause this, so I wish to re lock it. Could anyone point me in the direction of a good tutorial to do so? Cheers...

the link provided by our friend is quite good, that's where you have to head over
and about the tutorial, tha't so easy, just flash that FTF file via Flashtools
power off your phone, open flashtools, select flash logo, then FLASH MODE, then connect your phone as you are pressing down the VOLUME DOWN button, and let it do the rest
disconnect and enjoy your relocked bootloader

So I won't need to re flash the rom again? sorry. I'm a bit of a noob at phone modding. Pc's I can do. Not phones yet. Hahaha.

no, flash the relock ftf found in the dev section, and it just relocks your bootloader, your rom will stay the same

RElock won't affect you rom, BUT if you unlcok AGAIN, then at the very first start up of the phone when it is the first time after RE-UNlocking, it will have a factory reset
just wanted to let you know
but for now, NO, it won't touch your firmware

Just done it. Worked. Cheers guys,

Sus or PC companion will not work with unlocked bootloader.
If you want to use you must lock bootloader only when you are back on stock kernel.
DONT LOCK BOOTLOADER IF STILL RUNNING CUSTOM KERNEL. YOU WILL GET HARD BRICK

The easier way would be manually downloading 4.4.2 ftf and flash it using flashtool
download ftf from here
download flashtool from here
Make a backup before flashing ftf though as it will wipe the internal memory

As you're still using a stock based rom, open the dialer and type *#*#7378423#*#*
This will open the service menu, check under general service info (if I remember correctly). You'll find there whether or not your bootloader is unlocked.
Download flashtool by androxyde and the rom you want to flash (you'll find it here on the forum) and flash it via flashtool.
If your bootloader is unlocked, lock it with flashtool (though it won't make any difference as I'm pretty sure you didn't back up your DRM keys)

@St.Jimmy90
what if i provide him with my C6602 keys? can multiple devices be initiated with same keys?
I have rooted 5.1.1 / LB / C6602

by installing stock rom i meant to say android 5.1.1 firmware..
and in that service menu it says
bootloader unlocked allowed:yes..
so does it means i have alrady unlocked or it is locked and unlocking is allowed?

It means your bootloader is unlockable, but currently locked. You do still have your TA partition and DRM keys. To install stock 5.1.1 you can also use sony pc companion, it should be the easiest way. All your current data might be lost, though
