Root Unlock Bootloder issue on W8/X8

[darkillusions1]

Hi guys, I already tried unlocking my phone's bootloader so that I can use a custom kernel with it. It's just that I can't seem to unlock it. I already used all the apps like S1tool and the latest Flashtool to make it work, even the SEMC app, but still it doesn't unlock my phone. It has the code that has the uppercase "R" not the lowercase "r" and lastly the phone's certificate is recognized(DEVs might be familiar of what I'm talking about) and also my phone's open line(I can use itto any network provider)

Is there any other way in order for me to unlock my phone's bootloader?

Your help will be greatly appreciated.
