This is a downgrade for iPhone 2G. Some items In the kit don’t work well so I added a few working ones. You need two different iTunes versions. One for Redsnow and the other one for downgrading. Make sure to follow this video step by step or it might not work. If anything goes wrong just restore it with iTunes 11.0.5 on the same computer. Windows Vista supports everything linked below. (Vista is recommended unless you would want to use more than one computer) The method is XP or vista only.
Update: instead of using iliberty+ use Ziphone since the iPhone doesn’t show up with liberty.
If you already activated it just do a DFU restore to iOS 1.0 again and run ZiPhone (Will make a video soon for this)

is there any way to change the baseband on iphone 2 ios 3.1.3 04.05.04_G bar 04.04.05_G I can't downgrade back to 1.0 (previously succeeded a few times but the baseband is different or what?
itunes eroor -20
Any idea why my 747 2G only can go to 1.1.1? On 1.0 or any 1.0.1/1.0.2 it’s stuck on waiting for iPhone and it’s kicks itself out just after it reached the spinning and Apple logo back to the iTunes recovery mode and an error in iTunes.. I don’t know how I could fix that.. did. so many tutorials and if even has the old bootloader and 1.1.4 baseband idk.
