How do I downgrade my Firmware 5.51 to lower version because I have all the files and folders setup as the same way but its not working I downloaded Madden 2010, the only thing I can think of is an uptodated version of firmware is not letting me move on, keep getting data is corrupted this game cannot play message, not getting any UMDMULATOR option in my PSP, any help should be greatly appreciated.
I assume that you are on CFW not OFW. If you are currently on CFW and you have a pandora battery, download a program called Rains UltraLite MMS from here to make a MMS. Make sure that you follow the instructions to the letter and load the MMS and Pandora battery into the PSP and follow the steps for DCv8 on the psp screen and you should be to 5.00m33-4 after the flashing is complete.
I am new in PSP, Can you please tell me what is the difference between CFW and OFW and how do I found if I am in CFW or OFW. Another thing you mentioned that if I have pandora battery so same question again that how do I find that if I have pandora battery or not. Any help would be greatly appreciated.
a pandora battery is one that wil help you apply custom firmware to your psp. you don't have one. get a friend who has one, use it with a magic memory stick to do so. Before you do, find a guide to help you do it. Google is your friend. use it. If you don't know of anyone with a pandora, use your friend!!
