I have tried many times to downgarde my psp syatem. At the moment i am running the firmware 5.05. At first I tried to run the CFW 4.01 m33, when I tried to run that I would always get a message saying "cannot run file. data is corrupted." or something along those lines. I retry getting the data to install the firmware again and it dose not work again. Then I tried downloading CFW 3.53 m33 and that dose not work. After each firmware I try, I always get a message telling me that the program data is corrupted. If someone can help me come up with a solution to my problem that would be great. Thanks to all that read this and give me ideas, or solutions.
first, if it's a 2000 series with 4.01+ out of the box, or 3000 series, you're screwed.
second, you CANNOT run anything. you need pandora's battery and magic memory stick. and you cannot do it the easy way. you either have to hardmod, or buy one online.
