trying to remove bootloader doesn't work! topic

I've tried several times (several different versions latest is the last version is 14.4.a.0.157) to remove the bootloader, I think its because I removed the bootloader earlier and than put it back (did that with the flashtool) on but the fastboot/phone still recognizes the earlier unlock because it hasn't been put back the correct way.



So I was wondering has anybody found a solution? because I can't find it? (also searched XDA ...)
