CF 5.00 m33-6

ok im having problems playing psn demos, i don't play around with homebrew a whole lot but would like to stay on custom firmware but want to play psn demos as well. any way i can downgrade to 1.5 then all the way back to 5.00 m33 to see if that'll fix it? I've been here and there with the current goings on, do i need pandora or is it possible with out it since im already on custom FW

Reformat Flash1 first.

i compared it to my backup of flash1 and everything was the same, so i googled the error code that it was giving me and found this page.http://www.pspmod.com/forums/psp-sof...0020148-a.html and it worked for me.

bringing up the topic again.

This time i need 5.5 ofw because i want to play FF7.

Do i go down to 1.5 then up or can i just update?
