just bought a psp and it came with firmware 2.71 and a ta-082 motherboard. I've updated it to 2.80 so I could downgrade to 1.50 but when I go to the photo on my psp and open hen280 it freezes everytime. I get no blue screen and when I run Id storage changer it runs but I get an error (The game could not start 80020148.) Do I have to have a UMD game inserted while I run the patch? or Did it already patch it and I can go ahead and run update ver x.yz? Do I keep opening the Hen280 file until I get a blue screen which can take more than 8 trys?
