I really hate to cross-post here, but I'm in desperate need.
Please, anyone, help me. Also, if you could, please read the thread I posted, as there are several proposed solutions to the problem, which I have tried and all failed.So my friend's PSP had 3.03 OE-C loaded on it from a long ass time ago and he rarely ever used his PSP so it really wasn't a big deal. Well, he just bought a new game (Bleach Heat the Soul 4) which requires newer firmware so he brought it to me to upgrade it.
I did everything by the books and upgraded from 3.03OE-C -> 3.52 M33 -> 3.52 M33-4 -> 3.90 M33 -> 3.90 M33-2... and yet... UMDs refuse to load on his PSP? I don't understand what happened. I tried it with 2 seperate UMDs and both will not load on his PSP (3.90 M33-2) and will load on mine (3.80 M33).
If you could, my AIM is Knyghtmayre777. It'd be much easier with real-time help
