Default [Q] Problem with root recovery lg lte 2

Hey everyone,

I have to questions first is that i have an lg lte 2 phone and i rooted it using framaroot and the device rooted perfectly fine. Now i want to unlock the bootloader and install cwm,
The only method i found of doing it by LG Root pack (Root + recovery + unlocking bootloader) through usb debugging its the whole package.
As my device already has root access.will the above program re write the root or is there a chance of bricking the device?

And one more thing does framaroot unlocks bootloader?

Thanks in advance.
