**BrooksyX** · October 8th, 2006, 05:26

So basically I want reflash my 1.5 my with a clean firmware. Can I change my system number to 1.00 and run the 1.5 update? Or will this result in a brick?

You could always update to 2.00 and downgrade to 1.50.

Or actually downgrade to 1.0 then update to 1.5...

The easyest way is to go to 2.0 then back down to 1.50

Isn't that just 1.5 -> 2.0 -> 1.5?

Thanks for the response Acidburn. So he was just repeating what I was saying. Just making sure.

Well I dont really want to do any upgrading or downgrading. I just heard that you need to have a clean 1.5 to install dark_alex's custom 2.71 firmware. The only things I have are Dark_alex's custom firmware and I replaced the backgrounds. So if I remove the custom firmware I should be fine.

the mph downgrader and the 1.5>1.0 are the same thing, the mph d/ger tricks ur psp to think it's 1.0 so u can run the official 1.5(clean)fw, and the 1.5>1.0 downgrader gives u the the official 1.0fw and then u can update...the point is they do the same thing so either one would do
