Greenpois0n: Untethered Jailbreak For iOS 4.2.1 Released [Updated]

Chronic Dev Team

Chronic Dev Team has finally released greenpois0n to jailbreak iOS 4.2.1 for iPhone 4, iPhone 3GS, iPhone 3G, iPod Touch 4G, iPod Touch 3G and iPad.

The jailbreak is untethered and doesn’t need iOS 4.2 beta 3 SHSH blobs to be saved like iPhone Dev Team’s Redsn0w 0.9.7, which is currently available for beta testing.

greenpois0n RC5 is currently available only for Mac users. p0sixninja of the Chronic Dev Team has mentioned that the Windows version will be released soon.

greenpois0n needs iOS 4.2.1 installed on your iOS device for it to work, so if you need to software unlock your iPhone then you should not upgrade to iOS 4.2.1.

greenpois0n for Mac supports the following iOS iDevices:

  • iPhone 4, iPhone 3GS, iPhone 3G
  • iPod Touch 4G, iPod Touch 3G
  • iPad

greenpois0n does not support hactivation, so your iPhone needs to be hactivated via iTunes.

Please note that jailbreaking your iDevice may void its warranty so proceed with caution and at your own risk. Please don’t forget to backup your iPhone before you proceed. You can refer to this post for instructions on how to backup your iPhone.

You can download greenpois0n for Mac from this link (the site seems to be having problems at the moment so use the mirror site) or this mirror site.

Update 1:

Greenpois0n recommends a clean restore before continuing (it’s not ideal).

Update 2:

You won’t see Cydia after jailbreaking is complete, you need to restart your iPhone and launch the new Loader application to install Cydia on your jailbroken iPhone.

Update 3:

If you don’t see Cydia in the Loader app when you launch it then you can install it using Redsn0w 0.9.6 beta 6 (download link) from Dev Team blog just tick Cydia and don’t use the Monte option.

Update 4:

Chronic Dev have released greenpois0n RC5_2, which fixes various bugs including the Initialized error that many users were getting with greenpois0n RC5. So if you had trouble jailbreaking your iOS device then you can try using greenpois0n RC5_2. You can download greenpois0n for Mac from this link (if you’ve problems accessing the site use the mirror site) or this mirror site. Note: Updated the above link to point to greenpois0n RC5_2.

Update 5:

Mac users can follow our step-by-step guide for iOS devices below:

Update 6:

Chronic Dev Team has just released Greenpois0n RC5 for Windows

Update 7:

Windows users can follow our step-by-step guide for iOS devices below:

Update 8:

Chronic Dev has released a new version of Greenpois0n (Greenpois0n RC5_b3) for Mac, which now supports Mac OS X 10.5.x and also fixes many bugs. If you are facing a problem where greenpois0n RC5 opens and exits immediately then you try the latest version as the older version only supported Mac OS X 10.6.x. You can download greenpois0n RC5_b3 from this link (if you’ve problems accessing the site use the mirror site) or this mirror site. [Note: Other links in this post have been updated to point to the latest version]

As always, please let us know how it goes.

    I’m still on 4.1 with my iP4 and might just set aside my day off tomorrow and do this. It’s just such a pain for mento get everything back how it was since I always “restore as new” when upgrading firmwares to avoid complications. Wish me luck.

    • SirTap

      Is anyone able to help? No matter what program to jailbreak my phone I download, from limera1n to now greenpois0n, I am not even able to try it out, etc…I keep getting an error saying
      “Safari can’t open the file “greenpois0n” because no available application can open it.” What does this mean? I am a new mac addict, and really would love some help!!

      • Michael

        You need to download something that allows you to open .zip files. Normally Mac OS X allows you to do that automatically. Look for something like Stuffit Expander, I think it is.

      • http://www.drunkmunki.com DrunkMunki

        depends if your using an intel or PPC mac system, i dont think the software supports PPC anymore since its been phased out by Apple a while ago.

    nothing happens it says loading then nothing happens

    i dont want to be the first one to use it…

    • Mitch

      Ha me either! Engadget said it was rushed.. I think I will stick with my tethered Jailbreak for another 2 weeks for the bugs to get fixed… that is, if there are any. I’ve only had to tether boot my phone 2 times since I jailbroke it a month ago… it’s really not that bad.

  • Dae

    So does this mean that if we have a jailbroken phone, we need to upgrade to 4.2.1 then run greenpoison?

    • http://www.iphonehacks.com/ iPhoneHacks

      Yup, so if you depend on software unlocking your iPhone then you should avoid upgrading to iOS 4.2.1

      • Kotch

        what exactly do u menn software unlock… my iphone was unlock through itunes from my carrier , if i jailbreak it will i have any problem with that??

        • Terryg

          Unlock here refers to folks who want to use their iphones with a carrier other than AT&T.

  • ebda3club

    after Jailbreaking
    i got this in my screen

    Unable to find gBdevList
    Unable to find fs_mount
    Unable to find fs_unmount
    Unable to find fs_load_file

    • azdaspaz

      Same. Trying a fresh restore see if that help, cuz i just upgraded the firmware.

      • Kurtec

        Keep your finger on the home button…it will go through

    • TJ

      Same thing happened to me! After i reset my settings i tried again and it worked!

    • alphapetereson

      Continue holding down the home button even after the screen turns white…I had to do the same thing

  • Fear

    i have a question, i have an iphone 4 32gb jailbroken using redsn0w 0.9.6b4 tethered can i run this GP over the redsn0w 0.9.6b4 or do i need to make a fresh restore then use GP?
    appriciate ur help

    • http://yahoo.com MK

      yes u need to restore and then use GP

    • sirius69

      no you do not just run it over i just did it all program cydia ect all there

  • Chris

    That’ll teach me to be impatient. I decided yesterday not to wait any longer and did the tethered jailbreak on my ipad. Top thanks to the Chronic Dev Team anyway! :)

  • NUFC

    OK so I installed it,

    Iphone 4 32gig
    IOS Ver 4.21

    1st Attempt failed
    2nd installed loader, However when trying to install Cydia I get (NSURLError Domain Error -1100) I dont have a wifi connection where I am just 3g so it might be that or domain is down, I will try when I have a WIFI and update progress….

  • iPhone

    Hi,

    Is there a way to build a custom 4.2.1 so that the baseband does not get upgraded and then jailbreak with RC5?

  • CJAY

    Sounds like theres alotta problems with it already, thank god i dont have a mac and installed this lol

  • Fingers21

    Sounds like your all having problems! I’ll stick with my tethered jailbreak, I never switch my phone off anyway, so it’s never bothered me!

    • http://www.iphonehacks.com/2010/08/grooveshark-streaming-music-iphone-app-removed-from-the-app-store.html Your Momma

      Oh yeah? And what about the thousands of cydia apps that require a reboot? What happens if your springboard crashes while you’re away from your computer? Idiot. Tethered jailbreaks suck…just like you.

  • Adi

    I get the loader but no cydia in it? I have had the above errors also

    Unable to find gBdevList
    Unable to find fs_mount
    Unable to find fs_unmount
    Unable to find fs_load_file

    • jonas

      same here

  • DLock

    @NUFC
    IF you are having trouble with loader and not being able to install Cydia because of all the traffic trying to do the same thing, just download the latest version of redsn0w and follow the instructions and check the “Install Cydia” box only and it will save you a lot of time waiting for GP’s servers to get you Cydia

    • Adi

      If you select install cydia it will jailbreak your phone the redsn0w way and install cydia. You can’t just install cydia

      • DLock

        “For those having trouble getting Cydia via the GP Loader, just let redsn0w install it (don’t choose the Monte option)” – @MuscleNerd

        “(The order doesn’t matter: run GP after redsn0w, or run redsn0w after GP)” – also @MuscleNerd

    • NUFC

      HO can I install ultrasnow ?

      • shrug

        ultrasn0w is for carrier unlock right?
        you can’t.

        redsn0w is the tethered jb option. i think the idea is to use redsn0w to install cydia then GP to make it untethered.

        • shrug

          actually i take that back, it is possible but you need to preserve the baseband. if the baseband gets updated, you’ll be stuck and unable to unlock.

  • Pavel

    I get the same error:
    Unable to find gBdevList
    Unable to find fs_mount
    Unable to find fs_unmount
    Unable to find fs_load_file

    Tried it three time already. The third time did a clean restore as I read that was the way to go. It got stuck on the black verbose screen anyways, though. Seems like everyone is having an issue with this release.

  • bunnaz

    also, if you get the greenpois0n initialized screen & nothing happens just use recboot…

  • John

    GreenPois0n site is currently down. Wait until it’s back up and retry break and it should be error free. GP’s site / server is used to relay Cydia install. So that is probably the issue you are having.

  • Saikhnaa

    I have iphone 4 32GB on iOS 4.1 and not jailbroken. Baseband 02.10.04

    I can use greenp0ison withouth need to upgrade to iOS 4.2.1?

    thanks

    • Saikhnaa

      Am i right that if i want to unlock it using Ultrasn0w, then i should not upgrade to 4.2.1 and use greenpois0n?

      • Saikhnaa

        Quote “greenpois0n needs iOS 4.2.1 installed on your iOS device for it to work, so if you need to software unlock your iPhone then you should not upgrade to iOS 4.2.1″

        - What does this mean? Why can’t i upgrade to 4.2.1?

  • Kotch

    is there anyway to emulate run the mac version on pc??

    • JC

      Run Mac OS with VMware and then run the program or install Mac OS on a PC (neither of the two are simple). Do a google search for how to achieve this

      • Kotch

        ort thx ill do that

        • Jet

          I have Snow Leaperd install on an AMD machine with ati 5770 video card. Works great. Look around newer installers work great. Pretty easy to do.

  • BIGARMS

    Just tried this on my wifes 3gs,didn’t work got the same unable to load messages as above,tried 4 times and a fresh restore…….NO DIDNT WORK…..think ill leave my iphone 4 on jailbroke 4.1 for now!

  • Joe

    GreenP0ison is shit. Bottom line. MuscleNerd, Comex, and GeoHot are the only true jailbreakers. The folks at Greenp0ison must have been smoking too much weed when they put this piece of shit out.

  • http://www.motorbeam.com/ fas

    What the hell, throw all this and give me the unlock plz.

  • goonerlen

    this is not working for me tried it 10 times?

    is this version buggy? have the team rushed this out before geohot brings out rubyra1n to jailbreak 4.3 firmware and below?

  • JohnDoe

    I have an iPhone 4 with jailbroken 4.1 on it. Are there any real advantages to upgrading to 4.2 other than the free MobileMe option to find your phone if lost? I am not a gamer.

  • BIGARMS

    i just went for it on my iphone 4 and it worked,now got a custom logo on startup,the loader didn’t work so i had to download the latest Redsn0w and only ticked install cydia,its untethered and has no problems!

  • Adi

    Once you have used GP download redsn0w and install cydia works 110%. Servers are getting hammered thats why you can’t install cydia and only get the loader icon.

    • DLock

      Adi i worktold you it would work lol

I tried 10 times and nothing happen. Can someone explains please? I have iphone 4 and 3gs running 4.2.1

    • james

      you need RC5 which is mac only, rc4 is not for 4.2.1

    the 1st time got sucked on greenp0ison initialized (on phone screen) , so I turned off the phone , turned on again in DFU , retried the JB , and this time all worked great .

    LOOOOVE the Apple – skulc animation :D

    THANK YOU THANK YOU THANK YOU

  • Dexter

    Damn, GP needs Mac OSX 10.6 to run!!!!!!!!! WHY?????

    • Kotch

      you can create a partition and install mac on it.. thats what i did ….

      • iPhone 3G

        How do you do this can you teach me?

          If your pc is newer than p4 the download this h**p://thepiratebay.org/torrent/5996525/Mac_Snow_Leopard_for_PC_s__iATKOS_S3_v2.zip
          When download is done burn it on dvd at 4x speed and the follow this video h**p://m.youtube.com/index?desktop_uri=%2F&gl=US#/watch?xl=xl_blazer&v=3GfQGUr7X4I and it should work
          To install on different partition Google it.. There are many walkthroughs

  • Karen

    can you say mirror site?????

  • Monte

    dudes!!! on the last step continue to hold the home button down, never let off of it untill you see the greenpoison logo come up. yall are letting go of the home button too early.

    i dont seem to have anything in the loader folder. any help there?

    • Sam

      like Monte said, holding the home button much longer made the gp work flawlessly. :) and my loader seems to be downloading cydia fine…well after my fourth try lol

  • Steven

    The lastest IOS that I can download right now is 4.2
    Is that 4.2.1?

    • Kyros Koh

      iOS 4.2 is 4.2.1

  • Tony

    Thank you, Chronic Dev Team, waiting for Windows version..

  • Dean

    First jailbreak for my IP4 OS4.2.1.
    Got a “complete” message after JBing but no Cydia.
    Did I do something wrong? I tried restarting but still nothing.

    Feels and looks as if I did nothing with my phone :/

  • ordinary_guyz

    for those who got nothing in loader.. just rejailbreak it with Redsn0w 0.9.7b6 and click only Install cydia.. then you will have an untethered 4.2.1. it happens to me, i found nothing in loader.. so then i decide to jailbreak it with redsnow..
    after done, normally u will see a black cydia or crash cydia. but this time the cydia is working. so then i decide to restart the phone. after restart, the cydia didnt crashed. so thats how i realise how to solve the problem..

  • smate

    Hold Home button for a long time (minutes) it will take some time to pass first cycle, HOLD HOME until device turns off. Loader will most likely fail to install Cydia even if it shows up and download process starts, instead use redsn0w tethered jailbreak to install Cydia. Perfectly working on iPad.

  • Sixxdog_UK

    Worked great , many thanks , keep up the great work :)

  • DL Valure

    hey my loader wouldnt display cydia so i jus ran redsnow and installed cydia and it worked

  • larry

    i got the jailbreak but theres no cydia in the loader so i downloaed redsn0w so how do you use redsn0w to install cydia thanks

    • DL Valure

      jus run red snow like your going to jailbreak your i device but only check install cydia make sure you have the original ispw 4.1.2 and run it….mines worked perfectly

  • Dave

    same as everyone else:
    Unable to find gBdevList
    Unable to find fs_mount
    Unable to find fs_unmount
    Unable to find fs_load_file
    then initializing greenp0ison

    Tried 4 or 5 times with a clean install.

  • Sixxdog_UK

    OK :

    1) I was on JB 4.1
    2) Run GP
    That works but gives the usual cant find this that etc errors.
    3) Loader does not install cydia.
    4) Re-break with redsnow Install cydia only.
    Reboot device

    Simples , working 4.2.1 un-teathered , with working cydia.

    Thanks guys. YOU ROCK :)

      Keep the home button down until greenpoisoin logo shows on screen ,ignore the errors , then install cydia via redsnow.

  • http://www.rankvist.se Norrsken

    What a piece of shit…

    Can´t get the iPad into DFU-mode. it only restarts and tells me to connect to iTunes.

    I´ve tried with the iPad when it wasn´t restored and then I restored it, and it still doesn´t work. It only restarts and won´t get into DFU – or at least the step where the screen should show the greenpois0n logo doesn´t appear.

    Two tumbs down.

    Yeah, I´m using a iPad Wifi 32 gb.

    the site is down at the moment hence why downloads arnt working. its downloading the old version rc4

  • BIGARMS

    if it don’t work and you get stuck on the screen with the 4 errors,reboot phone and do a restore in itunes,make sure you back up your phone first,then try again with Greenpois0n and it should work……this happened to a 3gs i just done! The loader still didn’t work either so you need the latest Redsn0w to install cydia

  • slash

    I want to know if i upgrade to 4.2.1 and jailbreak with greenpoison will MYWI still work

    anybody?

  • Warezchewy

    I guess it won’t work if you have iPad baseband on your phone

  • Stranger

    I get the same error also:

    Unable to find fs_mount
    Unable to find fs_unmount
    Unable to find fs_load_file

    … I downloaded redsn0w but looks like I need the 4.2.1 file for it, won’t that rejailbreak then?

    • Sixxdog_UK

      You point it at the 4.2.1 ipsw , and it will create a new file , DONT use that file just allow it to JB and when this is done you have cydia on your iphone.

      the GP and RedSnow , allow for eachother to co-exsist as RS does not modify boot loader but GP does.

      • Sixxdog_UK

        MAKE SURE you check Install Cydia ONLY.

  • Henry

    It doesn’t work.. Have error so many times.. Is this buggy version? @@

  • BIGARMS

    it will jailbreak it again but it’ll only add cydia,yes you need the 4.2.1 file,search iphone firmware on google,its the top result,don’t panic ive done it already!

    worked great! thanks dev team!

    After I kept getting the error and empty Loader app, I installed RedSn0w and downloaded 4.2.1, then I installed Cydia with RedSn0w… WORKED! It’s untethered and has cydia now. Thanks Dev Team!

    • Sixxdog_UK

      Voila :)

  • Gavin

    I cant seem to get this to work!

    When I try the jailbreak only greenp0ison initialized (on phone screen)

  • MariO

    i restored my iphone 4, was jailbroken with redsn0w 0.9.6b4. i jailbreaked it with GP and didn’t get the Cydia icon in Loader, did it again, and didn’t show, so i kept GP jailbreak and downloaded 0.9.6b6 and installed only Cydia and it worked like a charm, also you don’t need to connect your phone to the computer after a reboot or shutting it down.

  • twoblacklabs

    Ok. Here is the trick to getting it to work. Mac version. Iphone 4 4.2.1 Download greenpois0n again. What we were trying to use last night, didn’t work. The file size last night was 1019kb. The version that works is 990kb. Worked fine for me. This is after 12 tries with the old version. BTW, it’s the same version number. Hint. Don’t let go of the home button while little snitch prompts you to let greenpois0n connect. In fact, why not turn little snitch off ahead of time and save yourself a step. Enjoy!

  • Paul Compton

    Ir u are jail broken with redsnow, do u have to restore first then break again or can u just run green?

  • Eddie

    I can report that this works. The trick is to just hold down the home button in the last phase of the install until you see the Greenp0ison skull. Then you can release.

    One minor issue, Loader returns an error that “You must be connected to the internet.” WiFi on the iPhone 4 (4.2.1) is working fine, I’m going to assume that it’s because everyone’s hammering the GP servers (???)

  • Nephariouz

    Anyone know of a way to sync iOS 4.2 with iTunes 9.2? I don’t like version 10 and won’t upgrade to it.

  • eddie-a

    this release is all sorts of fucked up.. no cydia.. website doesn’t have the actual file.. FAIL

  • Tom

    Thank you So much chronic dev team and thank you iphone hacks also, for your 3rd update about redsn0w it helped so much

    P.s. the version on the greenpois0n site did not work for me, i tried 7 times and nothing, but the mirror link did first time i recommend that. also i had to use redsn0w newest version to get cydia as it was not showing on the launcher :D

  • eddie-a

    cydia app is hidden! how do I get it to show up along with the rest of cydia apps on the home screen.. I can only find through spotlight

  • Justin

    So I followed the directions above, did jailbreak with GreenPoison (Link found for Torrent site on AppAdvice, obviously because GreenPoison site is down). Went through with GreenPoison had trouble with the loader application so I used Redsn0w 0.9.7b6 to install cydia only. Worked flawlessly, now I have untethered jailbreak thanks to GreenPoison and cydia thanks to Redsn0w.

    Does anyone know if this JB is working well with the iPad baseband unlock from the redsn0w tethered JB?
    My iPhone is JB and unlocked with this right know, but I don’t know if I’ll loose the unlock or something…

  • Teeb

    KEEP YOUR FINGER ON THE HOME BUTTON WHILE DFU’ing. 100% Works!

    As far as loader>cydia issue goes, i kept opening loader even eventually cydia showed up, just took about 15 minutes to install 100%.

    by the way, after installing a few apps, tethering 3g, qtweeter etc, my phone kept respringing at the home screen and i couldnt do anything.

    so I restored to 4.2.1 and im jailbreaking again.

  • vanillafrap

    I can’t open the GP app. I’m running on OSX 10.5.8. Any ideas?

  • Dustin

    Anyone know why after downloading Greenpois0n it won’t open. It keeps asking to relaunch…any help?

  • Morshed

    Redsn0w is the best for JB, no hastle no probs, no error.

  • Anand

    Getting error failed after a fresh restore too in ipad 3g 64gb ..

  • Kei

    I really, really, REALLY would wait a week.

    But don’t wait much longer. 4.3 will be out before you know it, and then you won’t be ABLE to update to 4.2.1 before jailbreaking!

  • Pun1x

    If you get
    Unable to find gBdevList
    Unable to find fs_mount
    Unable to find fs_unmount
    Unable to find fs_load_file
    Don’t worry just run redsn0w after that and load Cydia.
    It worked for my on 3GS and 4
    Make sure you are using GP rc2!

  • ali

    SOLVED: Greenpois0n RC5 “Failed” Error
    Ok, for those of you that are trying to use Greenpois0n to jailbreak 4.2.1 and getting the “Failed” error, here’s what I did and it worked. NOTE: The steps below assume that Greenpois0n.app is on your Desktop.

    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!

    Yes Yes Yes it works on ipad 64gb 3g thnxxxxxx

    I was able to jailbreak my 16GB wi-fi iPad I also got the
    Unable to find gBdevList
    Unable to find fs_mount
    Unable to find fs_unmount
    Unable to find fs_load_fil But the launch app showed up. I did try to install Cydia using redsn0w but it didn’t work. I kept hitting the launch app and it finally installed cydia. not sure what happened. also in itunes at one point had 2 ipad devices listed. mine and one that needed to be activated I deleted the second one. So far every thing works. Not sure if I just got lucky. I am going to wait on jailbreaking my iPhone4.

  • matatoto

    Finally. jailbrake my 3g,3gs,ipad
    follow tukkerstown method for ipad.

  • Greentime

    OK, I screwed this up a couple times before getting it to work flawlessly. I wouldn’t be afraid to try it as long as you back up your iphone first. After you back it up, restore it. Download the correct Green Poison and follow the instructions. After you load it restore the iphone to the correct date. Nothing will be lost and it will be perfect. I had to take the chance since I had started getting tired of having to teather boot and bring my macbook everywhere with me. Cheers!

  • Rick Burke

    Greenpois0n does work on 3gs, but just needs a little jiggery pokery if you’re getting the ‘fs_mount’ error. Keep the home button pressed a little longer after receiving the message (I did it to the end of the jailbreak) but it will work.

  • Dirtnap
