Untethered iPad Jailbreak for iOS 4.2.1, redsn0w 0.9.7

The guys over at the iPhone Dev-Team have released their “backup plan” (Redsn0w 0.9.7) for untethered iOS 4.2.1 jailbreak. The beta version of redsn0w will allow you to a untethered jailbreak of your iPad, iPhone 4 and iPod touch 4G on iOS 4.2.1.

This beta version is having some success on the iPad...RedmondPie's How-To

But I tried this on my iPad 16GB 3G with limited success.

Initially, I tried the untethered jailbreak on my iPad that had a tethered jailbreak. This got stuck in a reboot loop. Next I wiped it clean and restored the to iOS 4.2.1. I did another untethered jailbreak and received these messages from usbmuxd:

Exception happened during processing of request from ('', 50446)
Traceback (most recent call last):

File "/Users/xyz/Downloads/usbmuxd-1.0.6/python-client/", line 206, in connect
raise MuxError("Connect failed: error %d"%ret)
MuxError: Connect failed: error 3

redsn0w indicated that it was done and gave control back to my iPad. It was once again stuck in a reboot loop at the Apple icon with the rotating segments in the middle superimposed. This time after I unplugged the USB lead from it, the reboot loop stopped and my iPad started up immediately.

Here are some issues that I've run into with my working untethered jailbroken iPad...
  • Double pressing the home button results in the unit rebooting instead of seeing the task manager. Orientation lock was off before the jailbreak.
  • Triple pressing the home button results in the unit rebooting as well.
  • Plugging my iPad into the USB for a sync or whatever while iTunes is running results in my iPad rebooting, it stays stuck in the reboot loop until the USB lead is unplugged.

  1. Same problem here, however disconnecting from USB did nothing after 5 attempts. I'm done. I'll wait until they have a better solution.

  2. Bitchin...thanks for the update. This sight is the best!

  3. hi there, how do you stop the rebooting loop? I have remove the USB but it is still rebooting and rebooting... how do I get it to stop?

    Also how do you wiped it clean? I think I will just be a "good" boy for now, until a more stable jailbreak is available.

    Hope to hear from you soon.

  4. It works great.
    Thank you very much.
    Happy and Healthy New Year.
