The iOS hackers at the iPhone Dev Team have released Redsn0w 0.9.14b2 for Windows and OS X. The latest version of the popular jailbreaking utility brings two major improvements.

Redsn0w 0.9.14b2

First, there’s now support for downgrading the baseband on a wider range of iPhone 3G and iPhone 3GS models. This makes it possible to unlock an iPhone so it can be used on a different wireless network — something that’s not possible with the most recent basebands.

Second, there’s a new DFU IPSW option.

DFU stands for Device Firmware Update, and when your iPhone or iPad is in DFU mode it allows you to connect it to a computer to transfer code without loading the full operating system. This is how you can install custom code on a jailbroken iOS device.

Anyway, normally you enter DFU mode by pressing the power and home buttons in a certain combination, but the iPhone Dev Team says a number of folks with broken home or power buttons were complaining that they couldn’t get it to work.

Now you can use Redsn0w to create a custom IPSW file that will allow you to enter DFU mode even without entering the right button pushes. Note that you’ll be stuck in DFU mode until you use Redsn0w or another device to return to normal operating mode.

One reply on “Redsn0w 0.9.14b2 released, downgrades baseband on more iPhones”

  1. Hey, I’ve been trying for about a month to jailbreak
    &unlock my iPhone..

    In my most recent attempt I successfully jailbroke my 3GS,
    but instead of downgrading the BB, it upgraded it. I decided to unlock it
    anyway, with the intention of figuring out how to downgrade the BB later, but
    it wouldn’t unlock, even with my installation of ultrasn0w fixer for 5.1.1.

    So thenn, I tried unsuccessfully to jailbreak it with the
    recent update of redsn0w.. it didn’t jailbreak& remained unactivated.
    However, I didn’t initially realize that it was unactivated so I synced it from
    my backed up iPhone data with the result of only the name of my iPhone being
    changed to its previous one… all of my music, apps, etc. wasn’t on there.
    After this I tried jailbreaking it again with redsn0w 0.9.14b2 with still no

    Any ideas as to why this is happening& how I can fix it

    Thanks so much in advance to whoever to replies to this!!
