i made a downgrader for psp versions 2.71+ BUT i have been having some problems with it i can load the EBOOT file fine and then i wait a few seconds and this error comes up and says "The update can not be started The data is currupted. (UKN90000001)" if anyone could help me with this that would be great!
your "fake" updater EBOOT will never run as that error
number shows.....an updater EBOOT MUST always be
encrypted ....once you can encrypt then you can run your
downgrader but frankly please do find out how to encrypt :D
