Would I still be able to downgrade to 5.00 M33 if I upgraded to 6.20 OFW, then used my Pandora Battery + MMS to downgrade back to 5.00 M33? Or do newer firmwares block that?
I really don't play my PSP emulators much, only once in a while, and I want to use Remote Play over the internet, so I figured I could just upgrade to use Remote Play, then downgrade again if I wanted to play my Emulators and Homebrew again.
