how to downgrade official 3.0 to 2.2.1
Google is your friend.
i need to know this also, i keep getting all these dfu mode errors
i finally got it.. just downgrade your itunes to 8.1.1 then put it into dfu mode shift+restore choose the 2.2.1 firmware then thats it open quickpwn and your all set
Do you mean 2.2.1? Or do you mean 2.1?
2.2.1 DOES NOT work for me when I do this. I am getting a firmware incompatibility error.
I think we're in for many Apple tricks with the 3.x software. They have thrown in many gotchas already the DevTeam is discovering... Cat and Mouse.
Yeah downgrade your itunes into 8.1.1 from there you can turn your phone into dfu mode then shift restor the 2.2.1 firmware
Man! thi is hard.
