I put on 3.03 OE-C Winstaller so I (my 9-year old) could play the new DragonBall ISO (because it requires 3.03 firmware). The game worked fine and saved. I read that some people were having problems playing movies with this firmware, so I decided to try an original UMD (yes we have some) movie and the movie play fine. However, here's the glitch. When my boy went back to his game, the save was "gone". This was not a coincidence - we purposely tested the procedure again and got the same result - "gone" save data. I got one unhappy boy on my hands. I was so exasperated that I tried to go back to my original 1.5 firmware using 1.50 Recovery Winstaller. 1.50 Recovery installs, but when I look for the icon in the game column, there is nothing there but corrupted data. I tried reformatting a number of times and repeating the install - same result, corrupted data. When I tried to get to the icon using the restart/right trigger nothing happens. Can someone please help me out of this mess. I'd really like to get back to firmware 1.5 or at the very least have a properly running 3.03.
