Hi. Recently my friend downgraded his PSP and then we put 3.40 OE on it to play isos. For a while it worked fine and then suddenly it would start displaying the message "This game could not be started (80020148)" So we re-downgraded it to 1.5 and then back up to 3.4OE. And again, for a while it worked fine but yesterday it just started displaying that message again. So we decided to try the new firmware out (3.52), even included the update. The upgrade was successful so I tried to run an ISO on it again. The first time when I tried to play the ISO it just played the UMD which I had kept in the PSP. So I turned that off and restarted my friends psp. After that I tried the ISO again and this time it started displaying the same message: "This game could not be started (80020148)" Does anyone have any suggestions for me to try? Or know why this is happening? Notes: -He has always kept the UMD in -His memory card is a Sony 2gb and it is genuine -I've tried going to recovery mode and then setting it to no UMD. No luck there. -UMD auto-start is set to off -I tried more than one ISO I appreciate any help. Thanks!
