A) Run redsn0w 0.9.10b5 or newer and choose Extras, and choose 'Custom IPSW', allowing it to make the .IPSW with no baseband.
B) Under Extras, clicked "Pwned DFU" which will put the phone into a Pwned DFU mode allowing you to restore the custom firmware.
C) In iTunes, shift-restore and point to the custom firmware you created. The phone should update and reboot. If you experience the -1015, use TinyUmbrella to kick the device out of recovery mode
