My friend sold me his PSP yesterday, and I was planning on hacking it. Unfortunately, he has been very active updating his firmware, so it has 6.10 installed on it. I want to hack it, but I know I need 5.03 if I want to hack a Brite. Is there any way to downgrade the firmware? If it helps, I have a Monster Hunter Demo disc with the firmware 5.03 on it. And if it isn't possible, please give me the news in the easiest way possible.
