Not with SEUS or OTA from Sony Ericsson, it wil brick your phone. But you can flash the official whit flashtool, when ICS official comes for the arc
If you relock your bootloader you can update with SEUS again. Shouldn't cause any problems

But why unlock your bootloader if don't want to use costom ROMs of kernels? Whit unlocked bootloader and costom rom, or kernel, you can't update whit OTA or SEUS. And when you relock the bootloader you must first flash back to stock, or you will brick your phone to, when relocking your bootloader whit costom kernels.

Remember, when you unlock the official way, you lose your DRM, and when you relock it again you don't get back your DRM.
Hi,

If i am sure Xperia S and Xperia SL are the same devices, only difference is Cpu clock(S-1.5 Ghz SL-1.7 Ghz) So i think its the same relock way as with Xperia S.

I am pretty sure that the relocking ftf file over here works for S and SL - http://forum.xda-developers.com/showthread.php?t=1527159
Also, before you relock, just be sure to flash stock ics first with Flashtool and then flash the relocking ftf file.
Btw, you can still update to official JB with an unlocked bootloader. Once someone receives the update in his/her country, the ftf file will be made and released here for everyone. Also, Sony has their official Flashtool for unlocked bootloader devices.

Yes. You Can Flash Relock ftf. Both Are Same Device With Different Clock Speed.
It should not create any issue.
USING FLASHTOOL
First Flash The ICS (Exclude TA in Options)
Then, Flash The FTF Relock (Include TA in options)
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,

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..

why do u want to relock? do u have DRM KEYS/TA.IMG backed up somewhere in your pc ? to restore?
anways
with flashtool you can relock it and then unlock it again!
keep the original unlock key with you (just in case) or you can always ask sony for the keys

if the bootloader has been unlocked it can never be fully restored. you can never lock the bootloader the way sony did.
All you can do is to wipe and flash untouched stockrom and sell it
for flashing use flashtool / fastboot modes. you can do google for tutorial. its easy.
What about drm?

if you never took backup of your DRM then they are lost too! if you have taken backup then restore them manual. but whenever the buyer flash the device the keys will be lost too.
I have backed them up with TA backup

then relock your bootloader and sell it off. if the new owner don't change anything then the keys will stay intact.
however, if you could guide the new owner about it and email them the keys also , it will be fair deal
because you cannot use these keys on any other device.
Should I lock the bootloader first or restore TA first?
Anyone?
Answer: restoring TA automatically locks Bootloader.
But it needs root, so first restoring TA then flashing stock ROM with Flashtool.
