Important, make sure iTunes is updated to 7.5, in iTunes click help then check for updates There are a lot of people having trouble with downgrading and jailbreaking, so I made this quick guide so there will not be any more unnecessary confusion. This guide is made for PC. This is a guide to downgrade and jail break, it WILL NOT erase your music. Beware, this could give you the 1604 error, or other errors. USE AT YOU OWN RISK Step 1 Download 1.1.1. FW here http://www.[PIRACY.mu].com/?d=V7H8X2QQ (Someone reported it coming in a zip file if so unzip and make sure it ends with .ipsw) Step 2 Plug iPod in and open iTunes Step 3 Hold shift and click update (it is right above where it says restore) Please Register or Log in to view images Step 4 Choose the 1.1.1. FW you just download, and let itunes do it's thing Step 5unplug iPod open safari and visit tinyurl.com/36dsyz (safari will crashh and the installer app will be installed) ALL DONE! Step 6 I recomend NOT updating back to 1.1.2. Now wasn't that easy? FAQ -I followed these instructions and the file shows up as a folder or itunes gives me an error? try redownloading the file. Remember it has to end with .ipsw -If tinyurl.com/36dsyz is not working, can I use jailbreakme.com? Yes 1604 ERROR!? thanks Zombie_Killer A big thanks to the people who made jailbreaking possible! Also I recomend jimmyr.com because thats where I found the firmware download.
