This new release feature with iPhone Dev Team blog has mentioned as follows

Happy 4th of July!  Today’s release of redsn0w 0.9.14b2 improves the iPad baseband downgrade and should cover anyone who couldn’t downgrade with 0.9.14b1.  This version covers 3 different types of NOR chips in the iPhone 3G and 3GS (the earlier version covered only the most prevalent NOR chip).  We’ve also simplified the process and added logging to help diagnose any remaining stubborn iPhones.

The revised steps are:

    Connect your iPhone in normal mode, then click “Jailbreak” after redsn0w identifies its model and BB version (you needn’t pre-select the IPSW anymore).
    Choose the “Downgrade from iPad baseband” option (you needn’t worry about de-selecting Cydia anymore).
    Do a controlled “slide to power off” shutdown of your phone and proceed through the normal DFU ramdisk steps.

Should the downgrade fail to take, feel free to leave the redsn0w log in the comments below.  Use the “Extras->Even more->Backup” button to grab a copy of /var/mobile/Media/redsn0w_logs, then extract the log text file(s) from the zip and paste them into the comments (currently that log file is generated only during baseband downgrade runs).
This is the message from Redsn0w 0.9.14b2 DFU IPSW feature. Dev Team Mentioned as follows
We’ve gotten a lot of feedback from users who can’t launch a DFU ramdisk because their iPhone home/power buttons are broken or intermittent.  We’ve added a new redsn0w feature that lets you enter DFU mode as long as your phone is healthy enough to restore to a normal, everyday IPSW.  You don’t need to be already jailbroken to use this method.

In redsn0w, go to “Extras->Even More>DFU IPSW” and select an IPSW that is currently being signed for your device and that you’d normally be able to restore to without any hacks.  redsn0w will create an “ENTER_DFU_” version of the IPSW that you can restore to just like any other IPSW, except that now you’ll be dumped into DFU mode towards the end of the restore (WARNING, your screen will remain completely black…the only way to even know its on is that iTunes and redsn0w will detect it!).  The technique used by this feature is 3 years old but surprisingly still works today!
