I've just got a PSP off ebay and bought it cause its a Version 1.00. Before I read up properly, I updated it to 2.00.
I've now downgraded it back to version 1 using the MPH stuff, but when i load the version 1.5 update, i am faced with this message:
"The system cannot be updated. The update program is not applicable for this system (80000025)"
I've also tried resetting the factory settings but it seems like i can only have version 1 or 2
Any help would be well appreciated
cheers guys....
Get a different 1.5 update and make sure you have it on your memory stick in an PSP/GAME/UPDATE when you trick it to 1.00.
i've tried several... none of them work. i forgot to add it is a japanese machine. So do I need a JP specific update? does anyone know where i can get it?
another interesting note, when i do upgrade it to v2 it did come up with a failiure notice
But do you have to update on your psp WHILE while you run the overflow.tiff?
no, i did the overflow tiff thingy, and then it came up with the garbage, so i reset it and then run the 1.5 update. That's when i got the message
I don't know what the problem is though you could downgrade through PSPSetX instead of MPH Downgrader, you might find that is easier.
yeah try pspsetX
make sure you have a 1.5 update either on memory stick or umd and run pspsetX through eloader(tiff)
choose downgrade, and the app will change your version number to 1.0 to allow you to run the 1.5 update
you still get a freeze at 99% it is okay just leave it for 20 seconds then hard reset, press (0) on the blue error screen and follow the instructions for time, etc
woohoo you now have a 1.5
dont you dare use it for the wrong reasons
ill find you
arghhh
