Update: As of 29th April 2013, Relock bootloader file has been downloaded 80494 times!

As I already mentioned a week or two ago, there's unlock key in TA Misc after BL unlock.
This file removes the key, therefore relocks the bootloader.

Flash with FlashTool.

DRM can't be restored!

Download: http://www.mediafire.com/file/g1b5j7...bootloader.ftf

Feel free to donate if this helped you

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.

Also, there seems to be problem with Verizon Plays, usually this doesn't work for them, when unlocked via fastboot.
Enjoy

Blagus, you're melting my brain with these releases, man! We can barely keep up!

You sir are a gentleman and a scholar. Thanks for your work in this community!

Do you think that the trick to locking and unlocking CDMA is similar?

I'll see what I can do as soon as I get the device! With this trick I don't have to worry about one-shot opportunity!

Yes, and you can unlock again with same unlock key (yes, I'm back here, couldn't sleep )

Blagus, you are the man!

A few questions for you, but you don't have to answer if you don't want to :

1. What age are you (You seem very experienced)
2. When did you start coding and the likes
3. How did you get into this (I would like to start{have 2 years of coding under my belt, but lots more to learn still})

Thanks matey, just come across this thread, and want to try this at home, just a quick question, what exactly is contained, in the download link above, is it something we have to flash, or is it just a key, we have to input, in order to re lock bootloader, or all instructions are in the above download link? Thanks?
