Should I update my G510?

I take it the B171 I bolded is the version number people refer to. Should I update the phone, or will this lock me out of rooting later on?

Only asking as NOT updating my PSP allowed me to "root" that and I don't want to accidentally lock myself out of messing with this phone at a later date.

Thanks all
