Can't PLay UMD Movie

[dwoodma]

I used KXPLOIT to downgrade to version 1.5 but now I have a UMD movie I can't play. It worked on my original version 1.52. Can somebody pls help!

how did you downgrade with KXPLOIT
you either used the MPH tiff exploit or PSPSetX
any way i did a thread about this
if you are lucky the firmware number changers can work, you change your version number to 3.00 or something
the UMDloaders will not work though as they look for game eboots on the disc which obviously dont exist
it depends upon where you live though, because japan and america get the umds earlier the update required is usally lower, and the security is weaker
