I tried to update my psp to pro b10 and it was successful. I went into my system info and saw that it was running n 6.60 pro b10. Now heres the problem. I shut down my psp and when i turned it back on, nothing is working. I cant connect my psp to my pc. Everytime, it would just get stuck on the usb mode screen and when i exit out of it, it says that my memory card needs to be reformatted which i have done. The only way for me to connect my psp to the pc is to remove the memory card first, plug my psp into my pc, and then stick the memory card back in. Only then will my storage pop up on my screen. I try to reinstall pro b10 but everytime it restarts it says game could not be started 80020148. I thought well at least i can still play my games from my umd right? I pop my disc in and after a few secs of black screen, the same message pops up game could not be started 80020148. Someone please help. I have tried inserting the memory stick into a different psp and it works so i know that it has nothing to do with the memory stick.
