Downgrade PSP from 3.90m33 to 1.50 no pandora?

nobody

Ive got a slim psp and I want to downgrade it to 1.50 without the pandora.

Is it possible, and if it works can i install m33 again without pandora?

andrew

no.

The only way to install 1.50 on the slim is with time machine. the only way to activate time machine is with a pandora battery.

theres no cfw downgraders for anything past 3.80m33 yet

You do know you can make a Pandora battery right?

you can download and make a pandora on custom firmware look go to this site and put it in your ISO folder and go to ipl tools put standard single ipl then go to battery tool then make it pandora then take out battery pandora then charge then go up to a m33 firmware and run it again and convert it back and enjoy
