DON"T try to make a pandoras battery, I burned myself and broke my battery and had to spend 30 bucks to buy a new battery( I found this video 10 minutes after I broke my battery)WTF!!!!!

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 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
