Greenpois0n Jailbreak 4.1: No Mac Download – Your Windows Problems?

By Jamie Pert - Oct 12, 2010

Earlier today we announced that the Greenpois0n jailbreak for Windows was now live, this was particularly popular as a lot of people were having problems with Limera1n, therefore we thought we would see if many people are experiencing problems with Greenpois0n.

The good news is that we have received some comments suggesting that it is working pretty well, however as you would expect some people are still experiencing error messages etc.

I think it would be fair to say that Greenpois0n is not perfect as some people had to run it a few times before it worked, one reader suggests that not switching off their iPod Touch 3rd-gen (running iOS 4.1) at the start resulted in Greenpois0n working, so perhaps try that.

The most common problem seems to result in Greenpois0n saying that it cannot detect DFU mode, I have looked around for a fix to no avail, therefore if anyone knows of a workaround please let us know in the comments section below.

The Chronic Dev Team recently tweeted “if u need some help we are offering some support go to IRC: #greenpois0n”, I do not use IRC, however this could prove to be a very useful way of getting round all of your Greenpois0n problems. Another tweet explained that you must upgrade to iOS 4.1 on your iPhone/iPod Touch beforehand and 3.2.2 on your iPad.

Feel free to describe any problems you have in the comments section below, we will do our utmost to point you in the direction of fixes and workarounds when we find them.

Update: If you are still having problems check out the video embedded below, it has apparently helped some of our readers with the Limera1n and Greenpois0n jailbreak.

    Jailbreak was smooth on i4 but after some problems remains:

    – ambient sensor want work

    – problem with fly mode, sometimes can see orange aircraft icon but still can receive txt or incoming.. Sometimes can see just operator logo.. (after hard reset work ok for couple min and required reset again…)

    – problem with mobile data, need hard reset every couple minutes..

    This happens after jailbreak with greenp0ison

  • funkysy

    i Jailbreak my iphone4 with limera1n on sunday 10/10/10 without any issue and face time works a treat over 3g network. still going strong!!!!

  • Kyaktser

    trying to jailbreak iPod touch 3G 4.1 using Greenpois0n on my XP with no success. Cannot get past trying to get into DFU. Seeing the "Try Again" sign and reading the comments, it feels as if we are all in a lottery draw. Mostly 'Try Again' with an occasional 'winner'. 🙂 I had no luck with Limera1n either. What is this about preserving or saving the SHSH … I have not save anything prior to upgrading to 4.1. Could that be an issue?

  • Glenn

    Lost my carrier on iphone 4 after installing Greenpois0n. Can someone help please?

  • Kyaktser

    Limera1n worked great for my iPhone4 4.1 but not on my ipod touch 3G 4.1. Tried Greenpois0n for the ipod.. no luck so far. not able to get in DFU mode. Tried over 10 times and restored about 4 during that time. phew!

  • civicity

    do i have to have itunes running before jailbreaking??? please i need a fast answer

    • Andrea

      Actually, running greenpoison will automatically close itunes. So the answer is no.

  • I have just updated and jailbroken both my iPad and my iPhone 4 without a problem 🙂

    Follow instructions, u can’t go wrong!

  • yoyodog32

    tried restoring after dfu mode just starts up and nothing happens after that it won't exploit it please help iphone 4 4.1

  • pete goodall

    tried both GP and limera1n, both didnt work for me so now in erasing iphone back to factory settings then i will try again , maybe its an issue with windows 7. if it dont work this time i will try it on xp, i will let you know later

      • Dirtnap

  • ronald difficile

    Gigolo Haiti said : It took me 5 times to get it worked. I had to restore the phone several times til it works. I do not think the Shatter Exploit works fine because after restoring the last time . I lost the Loader icon. Meaning : shouldnt this JB be forever? need suggestions

    • gRenGe

      Shatter exploit is not being used in this Jailbreak.
