First off I will *not* beg for help, it's demeaning. Second, I wasn't sure where to post this, Backup loaders, or hacking. Well here is my problem: I went to the shop channel to get a game (I already used the Safe Updater to 4.2), and I read somewhere that the update from the shop channel (after 4.2) is harmless. Well after I updated (still shows 4.2), I am now unable to use any USB loader, I am unable to install any cIOS, and I am unable to downgrade. Any other homebrew I use works fine. Can somebody shed some light on this problem (maybe possibly help me fix this)?
