I read there's no support for backup games on "kakarotos" 4.00 firmware, which isn't what i'm looking for. I also read that you can't downgrade to a lower version if it hasn't been installed on the console before, and i also read that it can. So i'm a little bit confused here. What should i do to downgrade from 3.66 to 3.55? Is it possible with a E3 Flasher/ProgSkeet etc? Is it possible at all?
Welcome to the forums
Yes you can downgrade from 3.66 to 3.55 via E3 Flasher/Progskeet/Tenseey(I'm not sure if I spelled write). The new E3 Flasher is solderless and there is a whole thread about it with tutorial.
