There's no point upgrading to 6.20 to then downgrade back to 5.03. Unless re-enstalling an official firmwre could fix the problem? You have nothing to lose actually and downgrading from 6.20 to 5.03 takes a few minutes.
I think you should just dump the umds you have and play them as iso files directly from the memory stick.
That's the whole point of installing a custom firmware on a psp... to play back ups, homebrews and add plugin support.
When the 5.03 GEN C for HEN is installed on your psp, does the umd slot still appears when you link the psp to the computer? I f yes, you can still dump your umds

I have a psp brite running cf 5.03 GEN C for HEN and have experienced problems to run some umds too. You can install the Promotheus add on for this cf and I'm 100 per 100 sure it will fix the problem
