My friends gave me their PSPs so that I could upgrade them to 3.90 m33, a slim and a phat. I am using my own PSP, slim on 3.80 m33-5. I followed the DDCv5 guide carefully and completely. I inserted my pandorized battery into my friend's PSP and the memory stick and I held onto the button I set to load DDC and it just normally boots. Please help!
