Basically, My system suddenly won't boot up properly anymore to the system menu. when I try to turn my system on normally, it goes through the process of the initial setup as though I turned it on for the first time, but when I'm configuring the settings; the screen freezes and I get the "system files corrupt" message. I am able to load BootMii and go into Homebrew channel. I also have access to priiloader 0.7 installed as well. I attempted to install 4.2U as a wad with Wad Managers but I still get the same result of the corrupted initial start up. I have attempted to also use ModMii's downloads but it didn't improve anything. I'm currently at a loss of what else I can do with this issue. One question I also had was if there was ANY way I can configure the wifi settings without the system menu? perhaps an app in homebrew channel? Thanks for reading and I look forward to your assistance.
