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

You cannot update by SEUS or OTA with an unlocked bootloader.. Why don't u simply flash the latest ROM?
If u want SE updates.. You'll have to Relock bootloader (check Namaste guide thread for it) with stock ROM (2.3.2) .. root .. then update OTA (Again check the Namaste guide thread for this too)
Note: Root does not need unlocked bootloader..
thanks Bro.
i have relock the bootloader.
and update into 2.3.3....
if i want to root,then i have to downgrade to 2.3.2 then update it into 2.3.3?

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.
Sent from my LT26i using xda app-developers app
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,

for the official update via pcc question it will inform you there is and update but you will not be able to install the official firmware through pcc even if UB and stock you can only update flashtool ftf file or with cwm flashable zip
yes you can relock your bootloader with flashtool to update the official way.
yes it will work especially if you are stuck in bootloop or brick as long as you can boot into flash or fastboot it

thanks for clearing my doubt
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.
Ok right now im downloading the ftf for the 4.3 update, here's what i'll do to try and root it.
-Backup TA Partition
-Flash 4.3 ftf using flashtool
-Unlock bootloader
-Flash a custom kernel to get recovery (doomkernel)
-Flash the supersu zip that can root 4.3
-Flash NUT's dual recovery zip
-Re flash ftf (kernel only)
-Relock (restore TA)
i'll report back if it works. im waiting for download to finish
EDIT.
im now running the latest update 4.3 and i have ROOT and DUAL recovery! Kernel i used was MEOW kernel to get recovery, flashed supersu fix and NUTs dual recovery zip. viola!

Nothing new here, why a new thread? It's already known that you can get root easily with an unlockable bootloader...

As far as I understood your DRM is gone for good.... If you don't have a backup you can't get them back.

Never. Sorry.
Won't unlocking our bootloader void our memory?
Then whats the point in locking the bootloader again??

I believe Ryoma... Was asking about unlockable = no Boot loaders.
Maybe we should call it a "Not-un lockable boot loader" -NUBL as it seems a lot of people get BU locked (un lockable) and BL locked (not un lockable) confused.
