Downgrade Problems (Seriously I need some help)

[Macman1993]

I wanna downgrade just for like an hour so I can get some stuff off the 1.1.4 version but I cant do it. I have the file I select the right one for restore but it starts and I get error code 20. And yes I am doing this in recovery mode. Please help

If you have a mac... you could jailbreak 2.0 and then install fwchanger to go back to 1.1.4 thus being able to download 1.1.4 apps.
