Well, i used masterchief's very helpful tutorial, but both mph firmware loader and fakeupdater refuse to work. mph firmware loader just says, after installing the firmware, that there was an error. fakeupdater finishes to the end, but my psp does not say that it is ver 2.50. I could see two possible solutions.
1. i have a japanese psp, and i've been ussing an american 2.5 eboot. I hope that this is the problem and not
2. I;ve used WAB firmware changer ver 2.5 in the past. My psp refuses to say that it is anything but ver 2.00 now, even when i run WAB again and tell it to revert back to 1.50 :Argh:
so, would someone be able to help with this, please?
