  • Chronic Dev Team Releases greenpois0n, Untethered Jailbreak for 4.2.1


    The jailbreak community is buzzing and rejoicing tonight as the culmination of weeks of waiting is finally here. Earlier this evening, the Chronic Dev Team released the latest version of greenpois0n. What we have here is a nifty little conduit to free your iDevice running 4.2.1.

    Although MMi will have more insight and coverage of the release of the hours to come, in a nutshell, what we have with greenpois0n is a program that enables you to perform an untethered jailbreak. You can simply reboot without any cumbersome need to re-jailbreak. So far, however, we understand that it's only available for Mac.

    It should also be noted that caution should be exercised in rushing toward greenpois0n, as the build is believed to have been hurriedly put together. Consequently, there's only a small number of people who can presently report back on their experience with the release. So, by all accounts, please stay tuned.

    To go get the Greenpois0n untethered 4.2.1 jailbreak, click here.

    Greenpois0n
    Edit Poseidon: For anyone who gets stuck on "Initializing" you will need to hard reset your phone (hold home + power). Put your phone back into DFU mode but do not let go of the home button... Run Green Pois0n... release home button when you see code running down the screen.

      It isn't SHatter. If it was, it would only work with the iPhone 4 and possibly the iPad. Whoever told you it was SHatter doesn't know what they're talking about.

      Tried this on the iPad got a weird screen with:

      Unable to find fs_mount
      Unable to find fs_unmount
      UNable to fins fs_load_file
      Greenpois0n initialized.

      It stays on that screen and that's it. Not sure if it worked.

      Its someone I trust. Because think about it, if on 4.3 the SHatter has been stopped than why not use it on 4.2.1??

      Ditto. I got the same thing. Not sure if it's because I was tethered with Redsn0w already...gonna do a fresh restore and see if I get the same message.

      Looks like this was a tad bit rushed. Not working on the iPad, not gonna try it on the phone.

      TypeRBass, let me know if a fresh restore works for you.

      Will do, I'm not about to try this on my iPhone 4 if it's getting these errors with the iPad...not a big deal to restore my iPad seeing as how I don't have too much on there to begin with.

      I am getting that on my iPad also, and it won't get past it, even after 10+ minutes.

      My iPhone displayed that screen briefly, then booted up successfully with Loader.app on springboard.

      I tried installing Cydia, but it failed three times at around 80%. After that, Loader.app disappeared. Im tried restarting, but it doesn't show up. I tried rejailbreaking, but now my iPhone shows the same screen as my iPad.

      isn't redsn0w only using the develop firmware file?

      I'd rather use official firmware, and this is easier to use.
