Help with Downgrade for E3 Card Reader

Hey guys,

I have a problem with downgrading my PS3. I have done everything up to the step where you have to press power/eject quickly with the E3 Card Reader that is "programmed with the downgrade files." I need to know which files I will need to put on it to program it. Also, will I need to upgrade my E3 card reader by dragging and dropping the e3downgrade file to e3upgrade?

Thank you!
