Hacking Using UMDs on CFW?

[ragingchaosgod]

Okay so... My friend used to play UMDs on her 3000 before the whole downgrader and CFW thing happened for OFW 6.20. When it did, we downgraded to 5.03 and put her on GEN C (with Prometheus, of course) and now we have no idea how to get UMDs working again.

Admittedly, I have no idea how to as I've never used a UMD in my PSP before... does it have anything to do with the UMD ISO mode?

Can anyone run the steps by me? If anyone wants to know, it's Harvest Moon we're trying to run.

Go into the recovery menu, go to configuration, and change the UMD mode to normal (UMD required).

you dont need to, umd's will show on the menu anyway as well as the stuff in the iso folder.
the real problem is if the umd has a game that wants firmware higher than 5.03

in that case, rip the umd to an iso using UMDumper.

then decrypt/patch it the usual way.
