GreenPois0n RC5 2 has been released, the update to 1.0 RC5 aims to fix an initialization error that some users reported. The “initialized” error seemed to be somewhat random, but it prevented the GreenPois0n jailbreak from continuing on the effected devices.

    I tried untethrae my teathered 3GS v. 4.2.1, BB 05.15.04 but with no succes!
    Have to use Redsnow to boot again, everithing Ok after, but still tethraed. :(

    • Parakeet says:

      almel, you can run GreenPois0n over Redsn0w and it will untether. I would recommend just a fresh jailbreak with GP though.

  6. Sooneey says:

    I’ve tried everything running this, going through terminal doesn’t do anything when i type

    chmod +x greenpois0n

    it just says

    james-hays-macbook-pro:~ iHay$ cd
    james-hays-macbook-pro:~ iHay$ /Users/iHay/Downloads/greenpois0n.app/Contents/MacOS
    -bash: /Users/iHay/Downloads/greenpois0n.app/Contents/MacOS: is a directory
    james-hays-macbook-pro:~ iHay$ open chmod +x greenpois0n
    The files /Users/iHay/chmod, /Users/iHay/+x, and /Users/iHay/greenpois0n do not exist.
    james-hays-macbook-pro:~ iHay$

    help?

  7. Sooneey says:

    that “open” was me trying different things before. I’m a noob and tried everything and nothing works :(

  8. DJR says:

    Sorry let me refine this:

    1. Open Terminal
    2. type “cd ” without quotes but with a space at the end and (DON’T HIT ENTER yet)
    3. Drag the MacOS folder into the terminal and press enter.
    4. Copy paste this: “chmod +x greenpois0n” no quotes
    5. Hit enter
    6. enjoy

  9. Dylan says:

    I tried exactly what you said DJR and it still crashes upon startup. It just wants me to relaunch, report, ignore, or reset and relaunch. Any other ideas?

  10. George says:

    I’m still having the same problem after trying the fix that you have suggested :/

    when i do that fix i get this….

    Last login: Sun Feb 8 17:11:27 on console
    george-towns-macbook-3:~ Gtown$ cd /Users/Gtown/Desktop/greenpois0n-1.app/Contents/MacOS
    george-towns-macbook-3:MacOS Gtown$ chmod +x greenpois0n
    george-towns-macbook-3:MacOS Gtown$

    Help!! please.

  11. gio says:

    this worked for me up until i open loader. theres nothing inside it…

  12. DJR says:

    odd i have no idea then

  13. Draco says:

    Same things as well….works fine up to loader but it jus says Loader and there is nothing inside…..what now??

  14. Alex says:

    It worked ! Juste connecte to Wifi instead of 3G

  15. Draco says:

    i am on wifi

  16. Alex says:

    It needs to be a very good network.

  17. Rock_Bege says:

    1. Make sure you’re using Greenpois0n RC5_2
    2. Make sure device is connected to your Mac
    3. Open Terminal
    4. Type “cd Desktop” without quotes and hit enter
    5. Type “open Greenpois0n.app/Contents/MacOS/greenpois0n” without quotes and hit enter. A second Terminal window will open and Greenpois0n will start
    6. Follow the instructions in Greenpois0n to enter DFU mode and it will jailbreak
    7. Once jailbroken, a green “Loader” will be added to your device. This is supposed to allow you to install Cydia, but mine would not. If yours is the same, go to step 8
    8. Turn off your device
    9. Open Redsn0w 0.9.7b6
    10. Make sure the only option checked is “Install Cydia”
    11. Follow the instructions in Redsnow
    12. Voila! Cydia is installed, and you have an untethered 4.2.1 jailbroken device!

    credit to sumsh for this!

  18. Dude says:

    Thanks for the advice above.

    I haven’t tried it yet but will certainly do. Just don’t like the idea of running another JB (Redsn0w) over my iphone which would have been JB-ed by greenpois0n. If only greenpois0n would make it easier for everyone.

  19. Mike says:

    Ok, I have followed Rocks instructions to the “T” and here is the error I get on the 2nd terminal:

    Reason: Incompatible library version: greenpois0n requires version 6.0.0 or later, but libcurl.4.dylib provides version 5.0.0

    apparently I need library version 6.0.0 or later.???

    this is soooo confusing!

  20. Dude says:

    Rock’s instruction works for me. Mike, perhaps what you can do is to do a restore to the factory config. Unlock it via iTunes and proceed with the JB. See if this works for you as it works for me.

  21. Mike says:

    my problem is that greenpoison wont even start. My iphone hasnt entered into it yet. I have my iphone JBed with redsnow (tethered ofcourse) and apparently I can JB it with GP without even having to UNJB my iphone now. So Im just hoping I can get help figuring out why the program isnt even starting on my macbook. frustrating eh! lol

  22. Rock_Bege says:

    Mike what version of OS X are you running. I believe you must be running 10.6 (Snow Leopard)

  23. Rock_Bege says:

    But your understanding is right, If you are currently jailbroken via redsnow (tethered) you can run greenpois0n rc5 over the current jailbreak without having to start from scratch. If so then just ignore steps 9-12

  24. Mike says:

    ahhh Im running 10.5 leopard. Didnt know you had to be running snow leopard. thanks bro!

  25. Joel says:

    I can’t get this to work from my mac laptop. First:

    – there is no “sleep” button on my MacBook Pro
    – there is no “home” button on my MacBook Pro

    What am I doing wrong my friends?

    Peace !~

  26. haha says:

    LOL Joel! :))

  27. Rock_bege says:

    Joel-

    It is referring to the sleep and home buttons on your I OS device (whether it be iPhone,iPad or iPod touch) sleep button refers to the botton on the top (which is also the power button) home button is the circular button on the front of the device

  28. [...] For those encountering a problem where the app stalls on “initialized”, you can download GreenPois0n RC5 2 to resolve [...]

  29. Tracy says:

    GreenPois0n.app opens fine for me, I didn’t need to change any permissions or anything.

    Very easy jailbreak.

    BTW if the Loader is empty, try again because the servers are swamped, it took me a few times before Cydia installed because of it.

  30. josh says:

    Incompatible library version: greenpois0n requires version 6.0.0 or later, but libcurl.4.dylib provides version 5.0.0

    How do i fix?

  31. babbe says:

    Rock_Bege YOU ARE THE MAN!!

  32. jbertot says:

    @Rock_Bege Wonderful ! Thanks a lot ! As for me the cydia downlaod worked perfectly

  33. Dr. Mo says:

    im trying to launch greenpoison, but it crashes..
    im using 10.5…do I need RC5-2? or does RC5 work on 10.5??
    please help

  34. [...] GreenPois0n RC5_2 がリリースされました。これで、一発 JailBreak [...]

  35. mrhek says:

    why are so many people having problems and why do they need to go to Terminal? Before I used Greenpois0n, I had the tethered Redsn0w 4.2.1 on my Iphone 4. All I did was download Greenpois0n, read directions to go in dfu mode and now im untethered. It was so simple.

  36. [...] GreenPois0n RC5 2 is out for Mac but it requires Mac OS X 10.6 in order to run, right? Wrong! Thanks to this hack from cmdshift we can get GreenPois0n RC5 running in Mac OS X 10.5.8, so those on older Mac OS X versions will be able to jailbreak iOS 4.2.1 using GreenPois0n RC5 too. [...]

  37. John says:

    I did everything fine, but suddenly mobile substrate crashed couple times, my iphone power it off and won’t boot again! Black Screen always, doesn’t matter if I press the sleep button or the home button or both together. :(

    Damn, did I brick my iPhone? Any thoughts?

  38. nsfw says:

    Wow, reading some of these comments, your license to operate computers should be taken away guys.
    If yer a MAC OSX user, pick up a unix/linux/bsd 101 book and learn some basic stuff like how to change a directory and how to make a file executable. Your life will be a lot easier. Maybe learn VIM too.

  39. Dominic says:
