Relocking bootloader for xperia device

If you want to return to stock and/or need warranty back, you should need to relock bootloader. First install stock ROM and kernel and then relock bootloader, else you will have problems. Depending on the unlocking method, there are 2 ways to relock.

1)TEST POINT METHOD
Start S1 Tool and click Restore button.
Bootloader should be relocked automatically.

2)OFFICIAL METHOD
Will not work on test point method,
because bootloader was patched there ant not unlocked.
1. Make sure you have installed Flashtool.
2. You should download Xperia_Relock_Bootloader.zip file.
3. Extract that package, there is a .ftf file.
4. Flash the .ftf file by using Flashtool.
5. Your Bootloader will be locked.
