    Sony PSP Custom Firmware 3.90M33

    With only 3 days the official firmware from Sony, the homebrew scene now can enjoy the custom firmware update form th M33 team.

    I myself did not have the time to upgrade my 3.80M33-5 firmware to the latest one. I will try it at home later.

    Here are the download links from the official site, 3.90M33 , make sure after download put into your ms0://PSP/GAME folder , where ms0 is your drive letter. Also dont forget to download official 3.90.PBP and put in on UPDATE folder. After that goto your XMB and start the installer.

    Have fun with your new CFW!!!

    UPDATE : No more M33 CFW for your sony playstation portable
