I know how relock my bootloader and i have a TA Partition Backup.
Can i relock my bootloader safely if i am on the 15.1.C.1.17 firmware (C1905) but i unlocked it on the 15.1.C.2.8 firmware.
I have stock rom and kernel.
Because somebody told me that the TA partitions are different between firmware.
Yes you cannot relock lock on different FW just flash a ftf by flashtool of same fw...

But what if i updated it on the 15.1.C.1.17 firmware via PC Companion to the 15.1.C.2.8 firmware, so i dont have the same .ftf that i unlocked it on.

Hello guys, I have a Xperia S and I unlocked my bootloader to install OpenSemc. But yesterday I went back to stock ICS using Emma, to later get a direct update to JB. But I know that I can't do this update using unlocked bootloader, because it will "brick" the phone. So I'm wondering if I re-lock the bootloader to get this update, will I be able to unlock it again using the same unlock key and install custom ROM's again?
Thanks in advanced.

You can get the JB update even on unlocked bootloader. No need to relock the bootloader.:good:
Just avoid OTA updates though.

Hmm, you mean through PC Companion and SEUS, or through .ftf files made by users?
But if I re-lock the BL, will I be able to unlock it again? That's what I want to really know, hehe...

If you relocked your bl you can't use PC Companion or SUS. This will brick your phone. You should use FlashTool or EMMA.

I don't think I can agree with you. 3 days ago I relock my BL and Update my phone through SUS.
Yes Pharix is right. The device may get bricked only if u try using PCC with unlocked bootloader. With locked bootloader nothing wrong should happen.
Edited:- Because of abcdjdj's comment below. But i mentioned to keep the bootloader locked just in-case ! As saying that the chances of bricking the device is higher when the bootloader is unlocked than locked bootloader.
Thanks all you guys!

Actually it is not possible to brick an unlocked BL phone by using PC companion. It won't update at all and will give a modified software error. Ota update will definitely brick.

so if its brick via ota, can't we recover it by flashing any other ftf via flashtool?

Nobody knows...
But why do you want to know that? It is always dangerous to do such a thing.
Do we need to flash the official Jb kernel.sin or the PC companion is going to install automatically wrt Ftf? I mean after relock bootloader & installing official ftf via PC companion,

PCC will install full firmware automatically (and bug-freely).

There are two different 'FlashTool's.
One is from Sony (that's not the one you want to use) and the other is Androxyde's FlashTool.
Androxyde's FlashTool allows you to flash .ftf files and also unlock and relock your BL.

Yes bro there is A way,,,, you can get the official 4.3 update by flashing a 4.3 ftf file in your xperia using flashtool and you can relock the bootloader if you had made a TA partition backup.
From this thread you can download the official 4.3 ftf file - http://forum.xda-developers.com/showthread.php?t=2695293

ta backup has nothing to do with relocking bootloader
it is used to save some features of sony
relocking has not been made yet
and why would u want to relock?

To use SUS, you must have a locked bootloader. For those who have an unlocked bootloader, just wait until someone uploads an FTF. FTFs can be flashed on unlocked bootloaders using Flashtool by Androxyde.

You can easily relock the bootloader in just two steps.
Flash only the kernel via flashtool and then relock the bootloader also via flashtool.
You can't go wrong if you've used flashtool before.

And can we flash a custom kernel like maximus kernel while relocking?

The process is quite simple but do it at your own risk..
Turn on your computer's internet..
Open flashtool and select flashmode..
Select the firmware, then exclude everything but kernel (Remember only kernel should be selected, exclude everything)..
Uncheck every option in wipe..
Flash the mobile, it should take just 4-5 seconds..
Don't restart yet, disconnect your mobile..
Open BLU option in flashtool..
Connect your mobile, a dialog box will open, just click on relock..
(Remember, don't turn off the internet connection untill the bootloader is locked)
Restart your phone, it'll still be rooted and you'll be able to get all official updates..
Only thing you'll lose is the cwm recovery..
