No, you do not need to unlock anything.
Just untar that in a folder (use 7zip, first time you will end up with a *.tar file. Use 7zip again, and you'll see all the files inside that), make sure you have latest USB drivers, reboot into bootloader, connect your phone to the PC and double click at "flashall.bat".
BTW, I'm assuming you are running windows. If not, there is a file named "flashall.sh", use it instead.
I just did that and my phone wasn't rooted, everything went right. I don't know how to proceed if your phone is already rooted.
Now I'm testing if i can root the phone. I'll let you know.
