u don't need a pandora, look in the homebrew section right here on this site, you can install 5.00 m33-6 using the chickhen exploit and hellcat's recovery package, and theres even a convenient installer that takes all the hard work out of it for you over in homebrew. The chickhen thing takes a lot of tries sometimes to get it to work, but it does work. Like s2h6699 said, restore your default settings, and try a few times. If it still doesn't wanna work for you, click on some stuff in your xmb and then try it. I dont know why, but it really dores help. And that thing with hellcat's recovery flasher does work too to get u a full fledged cfw, I've used it. Chickhen sucks, just go for 5.00-6
