Ok I get to the point where I have to put the fastboot  -i 0x0fce oem unlock command and after  time it comes up with answer that <remote:command not allowed> in that form. I'm stuck.....HELP!! Does it mean  the bootloader  can't be removet at all?

Did you check the service menu to see if unlocking is allowed?
