just put your i-phone into DFU mode by using redsn0w_win_0[1].9.6rc7b and file 4.2.1 or 4.1 after DFU mode start itune and presh shift plus ok to restore with 4.1, do not worry you might get any error , if you get any error try to restore with 4.0 will upload the file but will not complete confirmation from the server disconnect the phone the phone will be recovered to uprade mode and will be 4.1, just jaibreak with redsn0w_win_0[1].9.6rc7b by using 4.1, remember ipad base band is not neccessary because baseband already upgraded to 16.05 , do not worry just use install ultrasn0w.deb via iphone folder without wi-fi and reboot twice
