I am running 3.40 oe-a and it was working fine for a couple days..After awhile I turned my psp off and when I turned it back on I tried to play my isos..I booted it up but it jus stayed at a black screen??.. can someone please tell me wat is goin on?
In that case you must have No-UMD mode enabled. Go in cold boot mode, AKA hold the R button when you turn your PSP on. Then go to configuration and turn it off. If that doesn't fix it, then use the 1.50 recovery then re-install 3.40 OE-A. I do believe you must have No-UMD enabled though.
