Good news for those of you with A4 devices that recently updated to iOS 5.1.1. The Dev Team has just released RedSn0w 0.9.11b4 with a handful of improvements, including full tethered jailbreak support for the new firmware.

The Team has certainly been busy over the weekend, as this is the fourth iteration of the 0.9.11 version of the software, which was just released on Friday

RedSn0w 0.9.11 was updated to b4 before we even noticed there was a b3, so we’ve included both changelogs:

“Version 0.9.11b3 should fix the spurious “Restore failed” messages people were sometimes getting, and it behaves better with nearby devices that have wifi syncing enabled!

Version 0.9.11b4 completes the tethered JB support for 5.1.1 on A4 devices and earlier, including proper “Stitching” and “Custom” creation of NO_BB IPSWs.”

You should only need to download the latest version of RedSn0w if you are looking to jailbreak your A4 device on iOS 5.1.1, or have been having problems downgrading your A5 device’s firmware. Otherwise, previous versions should suffice.

As always, you can find the RedSn0w update on our Downloads page. And if you need some help using the software, we have step-by-step tutorials on how to both downgrade and jailbreak your device using the utility.

      • hi ihave iPhone 4 iOS 5.1.1 baseband 4.12.01 want to unlock it

  • think so

  • think so

  • I don’t even know if I’ll update and rejailbreak my iPhone 4. I’m happyly jailbroken on 5.0.1. I think I’ll just wait for the new iPhone and the Jailbreak for iOS 6.0 which will be a lot of months away.

    • I would update. 5.1/5.1.1 includes some big bug fixes and speed improvements. Trust me.

  • Isn’t it only MuscleNerd that works on the Redsn0w and he is the only iphonedevteam ?

        Jesus Mesa meant A4 devices, not A5 devices..
        Is the procedure to downgrade A4 same as A5?

      • Yes use iFaith or stitch an IPSW using redsn0w if on osx

  • Would you still need to select the older firmware to do the jailbreak or can we select 5.1.1 firmware now?

  • Brace yourself, untethered jailbreak is coming!!!! 😀

  • patience is virtue
