How to relock bootloader?

I unlocked mine way back when it was on Android version 4.4.2.. Now there's an update to 4.4.4. but I can't update it since I have an Unlocked Bootloader right? Slightly frowning Face. So.. Is there a way for me to lock it back? 

My Phone are Xperia M2(D2305)

Re: Bootloader Relock?

Yes, I managed to update it to Version 4.4.4. using the flashtool. Now.. I can't find a kernels or cwm recovery (whatever it's called) for it.  I have looked everywhere on google and I can't seems to find it.
