Downgrade 1.1.2 para 1.1.1

1. Download the 1.1.1 ipsw firmware file from Apple. If the downloaded file has the extension “.zip”, please remove it and modify it to end up with a filename ending in _Restore.ipsw

2. Reboot your iPhone holding the top (power) and home buttons BUT release the top button 10 seconds into it (right after the screen goes dark) and continue to hold the home button until iTunes detects the phone in recovery mode. The iPhone screen will appear to be off, but start iTunes if not started yet .


3. Restore your iPhone by pressing and holding the ‘Shift’ key on windows or ‘option’ key on Mac, then click ‘restore’ to select the 1.1.1 firmware file you downloaded earlier. The restore should go through and errors at the end with error 1015. However you will notice that the iphone is in DFU mode with the connect to itunes screen from 1.1.1.

In order to kick the phone out of that mode I just had to launch iNdependence version 1.2.5 and wait a minute or so.

Now you are ready to follow the easy steps at the following LINK in order to reactivate the phone:
