If you know about custom firmwares for iDevices, you may also know that to use any custom IPSW firmware on any device, you must first enter Pwned DFU mode. The simple DFU/Recovery mode can not be useful to restore to custom IPSW. If you try to do so, you'll get error in iTunes. So here in this tutorial, I will show how to enter Pwned DFU mode, and restore to a custom IPSW created with Pwnage Tool or sn0wbreeze.
There are two main tools available using which, you can enter Pwned DFU mode - redsn0w by iPhone-Dev Team and iREB by iH8sn0w. I will describe the both below.
What this process will do?
After successful completion of this process, you will have your device in pwned DFU mode which will be useful to restore your device with custom IPSW. The custom IPSW can be used for preserving baseband, jailbreaking purpose, plus to have some extra features like larger ROOT partition, animated boot logos etc.
Things you need:
- Download latest redsn0w from here OR iREB from here
