oh downgrading MSET. MSET is the real name of the system settings app. when you downgrade MSET you're only downgrading the system settings app to make it exploitable, not the console as a whole. You'll be fine
ok so ill go do that now, so after that do i use the official gateway install guide through cubic ninja? and is the MSET way of using CFW more reliable cos every 3rd or 4th time i use the browser hack it fails
I'm not sure about gateway since I dont have experience with it. CFW kinda makes gateway useless for me
The DS profile boot rate is a lot better than the browser but there will still be times where it wont work so you'll have to restart the system, since the boot rate isnt 100%
As for your second question unless theres another option for AUS then yeah AUS=EUR. AUS and EUR systems are essentially the same
