Another great innovation introduced with redsn0w 0.9.14b2 is the ability to create a custom firmware that automatically goes into DFU mode after restoring with iTunes. This feature is very useful for those who have keys or Power Home damaged and can not get into DFU normally. To install this custom firmware, you need a Jailbroken iPhone already.
1. In redsn0w go to Extras> Even More> DFU and select the IPSW file. Ipsw corresponding to the most recent post fimrware IOS for your device (eg iPhone OS 4.2.1 for iPhone 3G and iPhone OS 5.1.1 for the iPhone 3Gs ).
2. Wait for the creation of custom firmware that will be called, for example, ENTER_DFU_iPhone2, 1_5.1.1_9B206_Restore.ipsw; this custom firmware must be selected manually in iTunes before restoring. The rebuild will occur normally, with the difference that your device will automatically go into DFU just before the end of the recovery. CAUTION: The screen is completely black, to verify the effective entry into DFU, check if the device is detected by iTunes in DFU mode and / or redsn0w!
