You will need to use one of the following tools to enter a pwned DFU-mode. Please note that pwned DFU-mode is different from DFU mode, there are additional patches being uploaded to the iOS device to allow custom firmware restore. 

The tools are:

• iReb (for version 3.1.2 and below)

Note:

• Turn off tinyUmbrella during restore, experiments show that it may cause problems.
