  • 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.

      just quit out and run loader again. keep trying.

      What are the best ways to back up all of your data?

      I would like to save my layout for my home screens, and all my Cydia apps. How can I do this?

      Thanks!

      I am just scared to do this. I have my iP4 jailbroken on 4.0.1 and it works great minus some weird thing where I lose service when 3G is enabled. I just don't want to lose my nice jailbroken iPhone.

      iphone 4 with 4.2.1 jailbroken with redsnow

      I can confirm that you can run GP with a jailbroke redsnow, it took 6 tries and it finally worked, it reboots perfectly and my cydia still works...

      by the way I didn't do anything special.....

      This is compatible with all devices.

      Wonderful. Now I have a Cydia icon that doesn't open and when I try to download in loader, it says "Cydia has already been installed!"

      This is becoming a real drama and I am wishing I had held off.

      I have tried now in DFU before opening and running Greenpois0n and also just following the instructions on screen.

      I am sure it's worked I get the animated connect to iTunes and then restart but still cannot find any loader app anywhere on the phone so how can I get Cydia back.

      Installed successfully. Then booted loader app to download Cydia. Don't think it downloaded properly, because now i'm trying to launch Cydia and nothing happens. What gives? What should I do now? Should I re-jailbreak?

      This is why I always wait about a week after a jailbreak is released to use it! How many times do they update their jailbreaks before they're final?? I bet there will be 2-3 updates in the next week!

      nvm was a failed download of cydia creating a false positive that it actually was successful
