Well if you had CWM recovery on it then it probably was an MDK phone that had a bootloader exploit.
Sadly though fused 6 means you updated it to Kit Kat... Locking that bootloader up for good.

As i was reading through, I think there is no rooting method for NC5 yet? if bootloader is locked is there any problem with device performance. what exactly bootloader do?
