Redsn0w 0.9.9b5 Jailbreaks, Creates Custom iOS 5 to Preserve Baseband for Unlocking

MuscleNerd et al has just released Redsn0w 0.9.9b5 for Windows and Mac to jailbreak iOS 5 and also comes with a new feature called Custom IPSW.

Redsn0w 0.9.9b5 is a “hybrid” version that allows you to make custom IPSW to prevent your baseband from being updated. This is required for those who need to unlock their iPhones.

Note that ultrasn0w will NOT work on iOS 5 for now. We need to wait.

On the Dev Team’s blog:

Update #13: With today’s official iOS5 release, redsn0w has been updated to 0.9.9b5 to include the public URLs for the IPSW files. This way, first-time iOS5 jailbreakers don’t need to supply the IPSW file manually. It’s still a tethered jailbreak on all except the old-bootrom iPhone3GS, and it doesn’t apply to iPad2 or the upcoming iPhone4S.

Because the jailbreak is currently only tethered for most devices, we’re not going to release a new PwnageTool yet. Instead, we’ve decided to build some of PwnageTool’s functionality into redsn0w (since you need redsn0w to “Just boot tethered” on every power cycle anyway). The new “Custom IPSW” button on the Extras screen will create a custom IPSW without the baseband update for 4.3.3 or 5.0gm (iPhone3GS and iPhone4 only, for now). Remember to NOT accidentally restore to the stock IPSW after you create the custom one! The custom one begins with NO_BB_ (for “no baseband”). On Mac iTunes, you select an IPSW by holding down the Option key while clicking “Restore”.

You must enter “Pwned DFU” mode before trying to use the NO_BB_ IPSW with iTunes (and your hosts file cannot be pointing to Cydia’s servers due to the new blob nonce mechanism they’re using in iOS5).

Version 0.9.9b5 is available only for Mac for now, until we can do more testing on the Windows version of “Custom IPSW”.

We’re currently working on a normal compatibility update for existing ultrasn0w unlockers. After that we’ll try to fix the iBooks issue on jailbroken iOS5.

Here are the download links:

• redsn0w 0.9.9b5 for Mac
• redsn0w 0.9.9b4 for Windows (version 0.9.9b5 after more testing)
