Earlier today we told you that MuscleNerd would be updating RedSn0w to include an improved 06.15.00 baseband downgrade. Sure enough MuscleNerd tweeted this evening that Redsn0w 0.9.14b2 is now available to download that fixes the 06.15.00 baseband downgrade for new bootrom iPhone 3GS’ and also adds a new “DFU IPSW” feature. Essentially what this will do is allow an iPhone, iPod Touch or iPad with broken buttons to enter DFU mode for a Jailbreak. This is done by restoring to an IPSW that you can currently restore to without any hacks or pwnage steps. MuscleNerd mentions that it still requires nearly an entire legit restore to kick in.
This new “DFU IPSW” feature is extremely useful because in the past if you had a broken hardware button it meant you would not be able to enter DFU mode period. At least now those with broken buttons will still be able to enter DFU mode and take advantage of future Jailbreaks.
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 own is that iTunes and redsn0w will detect it!). The technique used by this feature is 3 years old but surprisingly still works today!

We will have how to guides for using the new “DFU IPSW” feature, and also downgrading your new bootrom iPhone 3GS from the 06.15.00 baseband to a regular iPhone baseband in the near future. Until that time please leave any questions or further thoughts in the comments.
