Hey guys!

so i just watched a video on the e3 flasher install, and i had three questions that really keep bugging me.

my First was, after i have complete everything on the install video like he showed , and i successfully get the downgrade on the ps3 will i have to repeat the downgrading process every time i want to switch between a backed up game to my regular disc games or is it a one time only process, like once you do the process everything is pretty much final.

Second, will i still be able get on the psn? and play my games online?

and my last one, i have parental settings set up because i have a household of children running around. And i was wondering if once the full installation is complete with the downgrade process finished also, will I be able to set up the parental settings again, without having to worry about them being removed every time I have to do the downgrade process?(this one kind of goes with my first question) anyways thanks in advance guys.
