  • Greenpois0n For Windows Released: Untethered Jailbreak for 4.2.1



    Two days earlier we saw the release of GreenPois0n for Mac, and today we are presented with the Windows version. This is an untethered jailbreak for iOs 4.2.1

    As usual there might be some hiccups but you'll find plenty of discussion in this thread. Remember, anyone looking to unlock should NOT be updating their baseband. Do not be doing any updating unless you absolutely have to.

    The Mac version has also been updated and fixes many bugs and issues that people were having earlier. Check it out if your on a Mac and still having problems.

    Go get the Greenpois0n untethered 4.2.1 jailbreak now!

      Yes you'll need to restore to the original 4.2.1 FW first

      So are all the complications people are having prejailbreak? If/when I'm successful in running greenpois0n, there won't be any hiccups with stuff from Cydia, right?

      Thanks for the help x98, but I was hoping I wouldn't have to resort to restoring my iPod.

      My jailbreak is NOT working. Help?

      Computer: Windows 7 Ultimate 64-bit

      With a:
      - iPod Touch 4G
      - Running iOS 4.2.1
      - Had tethered redsn0w jailbreak

      Issue:
      After "Jailbreak", I was stuck on the the greenpois0n logo. It was like this for about 15 minutes, until it automatically restart it's self. It will NOT turn on, and is in a continuous restart loop, where it will just bring me back to the apple logo, then go black, then apple logo, then black, etc.


      ^^ Was my previous post. A little info, it says
      "unable to find gMount"
      and the other errors people are getting, except for me, mine still goes through to the code screen (others are just stuck there). Mine will complete, go to the greenpois0n skull, and do nothing. HELLLPP
