Flash with FlashTool.

You still can't get DRM back. It's gone from the phone!

Update:
If you unlocked your phone with SEtool/Omnius - any testpoint unlock solution - YOU CAN NOT RELOCK BOOTLOADER! IT'S PATCHED SO IT APPEARS LOCKED TO SE, BUT ACCEPTS UNSIGNED IMAGES VIA FASTBOOT! SO STOP ASKING ABOUT IT, AND STOP TRYING.
Enjoy ;)

Wow blagus, you are so great.
But is it possible to reunlock the bl with the old unlock key?

Anyway great news and big thx

Sent from my LT15i using XDA App

Yes, this flash just removes the newly created key which appeared after unlock. Have you tried it? If you're going to, report the result.

    You cannot restore DRM, it sits in another partition and is NOT included in normal firmware. So you can stop digging into HOWTO reenabled DRM functionality.

    I tried SE update and says that I have the latest software and I can install(actually downloads)
    Blagus, this is very awesome. I bet you have put lots of work into this. Great job.

    Edit: Just to let you know, I used V1 of bootloader locker you provided.

    Thanks.

    v1 version thing is there just to keep FlashTool happy :p
