I have been trying to downgrade my ipad 2 wifi and i have downloaded evasion, redsnow, and i of course have winrar. But when i download the firmware and do the steps of opening redsnow and going into extras and the even more tab i try to open the Pwnage folder and when i do it dosnt show the firmware. It just shows all the folders and stuff for it not the cube it shows in the tutorial. I am very confused here. Please help.
