How to upgrade to 2.0

Hi. I have a 1.5 PSP. With the things you can do in 2.0 (including downgrading back to 1.5), I would like to upgrade to 2.0. I was wondering if anyone could tell me how I would go about doing this? I just don't want to accidently upgrade to 2.6, or something. I already have the 2.0 Firmware downloaded on my computer, I just need to know how to upgrade my PSP.

Oh, and is there any reasons I may not want to upgrade to 2.0 at this time?

Thanks for your help.

I second that I need to upgrade a 1.51 to 2.0 so I can down grade to a 1.5

So, can anyone offer any advice?

Some help would be appreciated.

Sony has a simple little guide for updating on their official PSP site. The guide can be found here .

Thanks, couldn't find it anywhere.
