Not sure if I'm supposed to be asking this or not, but I have firmware 4.2U and whatever IOS that came with. When I originally installed HBC, I had the option to delete my IOS and replace with something else, but it was unable to get rid of my current IOS. I tried a few times and it failed each time.The amount of homebrew that I can run is limited, and I beleive it is the IOS that's causing me trouble.
Can anybody help. If I am not supposed to be posting about this, then let me know.

What homebrew are you trying to run?

Something that the rules say not to ask about. It rhymes with boader. I want to test out backing up a game THAT I OWN and seeing if it will play.

Then gtfo.
