Wondering if some people can answer my questions as I'm interested in buying a E3 Flasher.

-With the E3 Flasher am I able to switch between OFW and CFW without formatting the HDD?

-When downgrading do I need to format the HDD?

-What's the best method to use if I just want to do challenge lobbys on W@W and switch patches every once in a while? Would I require two HDD?

-What bundle of the E3 Flasher should I get if I want a method like the one I stated above?

-With does dual boot do exactly?

Thanks to those who answer my questions and I hope this is in the right section.
