RedSn0w 0.9.15b2 released to add fixes for 3GS and iPad owners

By , Oct 15, 2012

The iPhone Dev Team has released RedSn0w 0.9.15b2, which fixes a few items for owners of older devices.

The most outstanding fix is for 3GS owners with old bootroms — RedSn0w 0.9.15b2 brings back untethered jailbreak support for end users who fall into that category.

Most of the changes don’t pertain to owners of newer devices, but it’s always a good idea to ensure that you’re running the latest and greatest version anyway. Take a look inside for the full release notes.

Per the Dev Team’s Blog:

Update #1 (Oct 15): Version 0.9.15b2 fixes a few issues for 3GS owners: old-bootrom awesomeness is no longer forgotten directly after a restore, and iPad baseband upgrade/downgrade support is fixed (same production date cutoffs apply!). If your 3GS is currently tethered at 6.0 even though you have an old bootrom, just re-run redsn0w’s Jailbreak step (no need to restore). Don’t forget you can add some pizzaz with your own boot logo or a nerdy verbose boot.

So basically if you have a tethered jailbreak with an old bootrom 3GS, just re-jailbreak with RedSn0w to gain your untethered back.

Be sure to check out our full jailbreak tutorial for RedSn0w 0.9.15 here, and visit our dedicated RedSn0w page for further information.

You can download the latest version of RedSn0w from our downloads page. Do any of the fixes included with RedSn0w 0.9.15b2 impact you?

    • http://twitter.com/inemopsp Brad Nimmo

      I want to do same for iPhone 3GS but redsn0w give me error cause it tries to restore though redsn0w rather than makin me an ipsw….

  • http://twitter.com/iFixuriPhones iPhone Repair Depot

    The jailbreakers are referring to the iPad baseband that can be downgraded on the iPhone. Not upgrade/downgrade the actual iPad baseband… There wouldn’t be any benefit

  • http://twitter.com/iFixuriPhones iPhone Repair Depot

    “and iPad owners have a fix for baseband upgrades/downgrades.”

    They are not referring to the actual iPad, just the 6.15.00 baseband that can be downgraded to 05.13.04

    • http://twitter.com/inemopsp Brad Nimmo

      No they meant “iPad baseband” for iPhone 3G an 3Gs, which is baseband “06.15.00″ an since redsn0w 0.9.14b1 you can downgrade ur iPad baseband to 05.13.04 baseband… Witch means you still have unlock with ultrasn0w plus you get back GPS feature an now can offical restore with iTunes without makin a custom iPSW for preserving iPad baseband

    • $hrimp

      Its means a4 devices n down. U cant downgrade a5 devices yet. Only re-restore to ur current firmware via redsn0w with ur blobs saved

  • choco_ju

    I am looking for ways to upgrade to IOS 5.1.1 and then JB 5.1.1.
    I googled lots of forums and think if my device been JB before and have SHSH backup can upgrade it to 5.1.1 not sure If I got it right or wrong as now apple don’t sign off anymore
    my phone is 4.1 JB done by my frd whom we lost touch and can I upgrade it to 5.1.1 using the tiny umbrella? my cydia says I have 5.1.1 and 5.1.1 r on top barI am looking for guidelines for first time JB such as myself thx alot

    • $hrimp

      Tinyumbrella is a tool only used to fetch ur blobs n save them localy. Use redsn0w to stich a signed firmware and restore. U must have ur blobs save for the firmware ur tryn to restore to

  • kelly chavez

    I can’t update my iphone 4 to preserve baseband ios 6 because Resnow gave me error in the middle of update/restore. I ended up to restore back to 5.1.1 no matter how hard i tried.

  • DeBragg

    To check if u have old or new bootrom, just use redsn0w, put ur device in dfu mode,click Extras,then Even more, then Identity. A info page will be generated. Look for iBoot: 359.3 is old bootrom and 359.3.2 above is new boot rom. Alternatively, use iTools to check
