until bootmii comes out (maybe even with it) removal of the system menu's IOS will result in an instant unfixable brick. (short of an infectus) Also you can still banner brick, although with preloader you can easily recover from it (also with recovery menu booting)
The IOS is a seperate section of the "firmware" if you will. each IOS is used for a seperate purpose for the system. Some run games others run internal items such as the System menu it's self. on your firmware the system menu runs on IOS 30 if I'm not mistaken or you haven't somehow patched it to an alternative IOS. In other words don't mess with something if you don't know what it does and don't know how to use it and you will be just fine. The one thing you will want to make sure of with the games from another region is that you have the patch to bypass any and all disk update checks.... Because that will cause whats known as a semi brick. It's bassically a multi region System menu at that point and because of conflicting settings it will not work as it should............ In other words just use your head and you will be fine.
Get preloader, and make sure you have the Twilight hack installed, not in your SD, but installed. Because so many people forget to mention keeping the TH installed, I guess I took it out without thinking and bricked my wii. Thank god Target gave me a full refund! =D
No completely though. It depends on what kind of wad. If it was a banner-brick one, then he can recover easily.If you're talking about some super virus wad, then maybe. But in regular circumstances; for those who don't know all this coding mumbo jumbo, He's pretty brick proof.
Afif95: What makes you able to decide if he is to new to hack/brick his wii? We all went along this road once.....We all had to learn from someone/somewhere. Now, give the guy a break and just help him along and give him the best advice you can.....Not telling him that he's to NoOb to brick his wii....
