Untethered redsn0w iPad 4.2.1 Jailbreak Released for Beta Testers

by on December 26th, 2010

The iPhone Dev Team has released an extremely buggy beta version of redsn0w for an untethered jailbreak of your iPad, iPhone 4, and iPod touch 4G. Currently, the existing jailbreak for iPad on iOS 4.2.1 is tethered. That means when you reboot or run out of battery you need to re-jailbreak. That’s a pain that you don’t want to have to deal with.

This current version of redsn0w is for beta testers only, meaning if you want to go ahead and tinker, go right ahead. I wouldn’t recommend this until the final release of redsn0w is out.

To keep things manageable, this will be a Mac-only test program. We also request that any volunteers *NOT* need the ultrasn0w unlock (in case things go very wrong).

Right now, the “backup plan” requires that you have the 4.2b3 IPSW on your Mac, and that Cydia has your 4.2b3 SHSH hashes. Please don’t pirate that 4.2b3 IPSW! (We’re also working on a way that this technique might apply to all those with 4.1 IPSWs, but that’s not the first goal right now.)

If you fit all the above qualifications, please follow @redsn0w_testers on twitter for announcements, and use the comments section here for feedback. Thanks very much for your help, and Happy Holidays!

Update #1: We’re about to release the first beta using this new “backup method”, which redsn0w calls “Jailbreak Monte”. Here are some important points:

This is a beta tester program. It’s not a general release! Things can go very wrong, so please don’t even consider testing if you have pictures or other media on your device that you haven’t backed up!
For the same reason, please don’t participate if you rely on the ultrasn0w carrier unlock. Wait for the final version!
Until we fix some sandbox issues with bluetooth, the bluetooth functionality is disabled.

This very first beta1 is limited to iPhone4, iPad, and iPod touch 4G.
Cydia must have your 4.2b3 SHSH blobs saved on file. (As we approach a general release, we’ll provide a way to let you use locally saved hashes too).
You must already have the usbmuxd software installed and running on your Mac (this requirement will eventually go away too). The correct invocation of the relay is just as that page says: “./tcprelay.py -t 22:2222”. If the relay isn’t installed or running correctly by the time the redsn0w ramdisk has started, you’ll need to restore to stock FW again to try it again. Please test it beforehand to save yourself some time!
Please leave all feedback in the comments below (we really need your feedback to help develop it into a stable release!)
