So I have all the download requirements on my desktop ready to downgrade my friend's PSP. He said that his PSP is 2.80 Firmware. I'm downgrading his PSP, so I can also downgrade mine. My PSP is 3.51 Official Sony Firmware. I have read the guides that have been posted on here. But unfortunately, I still don't get it.
Here are my questions:
In order for the downgrade to work, the PSP has to be 1.50 Firmware? Correct?
In order to make the "Magic Memory Stick", the firmware must also be 1.50? Correct?
