Is it possible / difficult to downgrade a V1 iphone from 2.0 to 1.1.4 firmware?

If you can find a download link to 1.1.4, it is.

Right click on Check for Updates or on a Mac you press Option and then click, and then select the 1.1.4 IPSW file.

I read somewhere that it's more complicated than that.

Something about the baseband (I don't know what that means really)

you dont like 2.0?

apparently the dev team already JB 2.0

The baseband is changed in 2.0. Going back might be possible, but no one has released anything just yet to do it.

Here are two tutorials for you to look at, on Downgrading from 2.0 to 1.1.4:

BigBoss Tutorial
iClarified Tutorial

Last word of advice: Beware of 1604!

I've already went back to 1.1.4, much happier now.
I'll wait until Winpwn is out for 2.0, before I go back to 2.0
I followed the guide from BigBoss, but I also hade to use Ziphone
to downgrade bootloader before my phone would come out of recovery
mode. It takes awhile, but you can downgrade.

Thanks for the good info.

I was trying to do this yesterday and kept getting the 05 error with bootneuter. So I just quit for the night. It looks like the big boss tutorial was updated since I last looked at the page. I'll have to try it again later this evening.

I finally got around to doing this again today. After a couple restores, I finally got the baseband back to 04.04.05_G. Had to use the Ziphone patched program. now I can finally sell it.
