please help me. IM AN IDIOT. I tried to flash a .rar file i renamed as a .rco so I could have a custom XMB wave I downloaded and it was a .rar so I thought I could just rename it and it would work. I have 3.01 oe so I can run the system recovery by holding r when I reboot but I dont know what to do now. When I hold power to turn it all the way off then restart it shows sony computer entertainment, but then it freezes, WTF?!! Please, please help. Im at my moms right now so im aloud on the computer for now. but when i get back to my dads im not aloud, so i need help quick!
