Question about Sony PlayStation Portable (PSP) Slim (PSP-2000) Console
Please help me to find ways to how i can downgrade my psp version 5.01 to version 3.90
HELLO! There's no need to downgrade ur PSP. If u have upgraded ur PSP from the official site and a official firmware has been installed on to ur PSP, it won't execute games(ISO,CSO) from ur memory stick. It will only run games from the UMD. If u want to run ur games from a memory stick u have to install a CUSTOM FIRMWARE. Try www.psp-hacks.com these guys have many softwares on their site. Dont worry its not that hard to put a Custom firmware onto ur PSP.
