The system keeps logs of everything you run so it doesn't matter if you change memory cards, SCEI doesn't seem to really care if you use CFW unless you start cheating online or are giving yourself trophies.

Don't have a UMD video to test this but have you tried simply using the USB mount option in the XMB?
Same goes for dumping games BTW.

Hmmm, Could be a bad download of the update? Try letting the PSP itself download the update via the option in the XMB? Honestly im not sure but buntcher brings up a good question in does the memory stick work correctly? is it an official or knock off? If all else fails then yea pandora and an MMS sh...

Thay error means it can't start the game for some reason, I recall early versions of PRO C having issues with PS1 games so you could either grab a fresh copy from this thread here or it could be an issue with the eboot not being made correctly. http://wololo.net/talk/viewtopic.php?f=17&t=41249 I als...

Try disabling all plugins?

Grab the 6.61 update from the PlayStation site and run it, should update the PSP to 6.61 OFW and remove cIPL if its there.
Then install either ME CFW or PRO+cIPL patch.

Its as simple as place in PSP/Game/ and running the installer these days.

You have a cIPL compatible 2k, you don't need infinity to have a perma CFW. :/

It hasn't been done because it outright doesn't work on that hardware, doesn't matter if you can get the PSP to connect to the battery as setting the batt eeprom for pandora wont do anything.

3.67 is HBL only so unless you only want PSP based emulators and the such you will need to wait for TheFlow to release the updated HENkaku.
That will enable the use of Adrenaline for your firmware.

The library's and functions it uses would make it very clear afaik.
