In order to do that you neet to hold left “ALT” button ( Mac ) and click on Restore, then select your custom 4.2.1 firmware created with PwnageTool and click “Ok”

    I had this same problem on my 3Gs. My phone won't boot, goes into DFU mode but then has an error 1600 everytime it tries to restore using Mac iTunes 10. Tiny umbrella doesn't help nor does attempting to downgrade to 4.0.1 where I started. I'm bricked! Any help is welcome.

use latest version of iReb then choose which iDevice you have and it will stick it into 'pwned' 'DFU' mode then hit it with your custom ipsw.
