Just got Galaxy 2 today, but it requires a system update to play. Since I'm already running 4.2U, I don't know if it's a new version or if it just wants to reinstall 4.2. Haven't been able to find much talk about it, so I hope others are getting info. At the least I'd like to know if I'll still be able to use HackMii Installer to revert back, in case the system update messes with anything.

just install it. As long as you don't have anything not-supported here, you'll be fine, and even then, I don't know. My brother was wondering the same thing, but I told him to just update, and he did fine, I'm actually watching him play now. I also installed Bootmii as boot2 for him, so there was a contingency plan in place anyway

I havent done an update in ages and i didn't have to update. but i have update requests turned off in my system menu.

ok... That being said, go ahead and update, no reason not to

I ran the update included with the disc and it deleted the Homebrew channel.

Okay.

Re-install the HBC, then.
