Accidentally upgraded to 1.1.2? We now provide a downgrade service for people who accidentally upgraded their iPhones. See the bottom of this page for more information.

This is ONLY for iPhones that were upgraded, not iPhones that were purchased on 1.1.2.

Follow these steps in order: 

Step 1: Downgrading from 1.1.2 to 1.1.1

Step 2: iPhone Error 1015 (1.1.1) and 1013 (1.0.2) during downgrade process - Yellow triangle icon

Step 3: wiNstallerGUI - Installer.app - Jailbreaking process

Step 4: Baseband Reflash and launchctl using Putty process

After you finish, you can upgrade back up to 1.1.1 by first virginizing it.
