I am on an ipod touch 1g and I want to downgrade from 3.0 to 2.2.1. I have put it into dfu and then shift clicked restore and selected the 2.2.1 firmwire but i always get one of the 1600 errors or error 20. I have tried on the latest version of itunes and iTunes 220.127.116.11 and the same thing happened. Most tutorials say to use the one version of itunes ending it 35 but I cant find it for 64-bit. Does anyone know how i can downgrade. I also saw that quickfreedom thing but i think that that is only for the ipod touch 2g. And if it isnt is there anyway to use that method using quickpwn because im on vista and i dont want to have to install the things to make it work, plus im way more familiar with quickpwn. Thanks in advance!
