Default Curious about unlocking my MZ609

I bought MY609 second it already had the latest OTA 4.1.7 searched hi and lo I think but for some reason I can't seem to figure out how to unlock the bootloader nor root all I want to do is be rid of the bloatware and help this little monster run a bit faster and not be as glitchy!!! Lol any help with this would be tremendously appreciated thanks in advance guys
