How to Jailbreak iPhone 4 / 3GS iOS 4.1 with Greenpois0n

Chronic Dev-Team has released Greenpois0n to jailbreak iPhone 4, iPhone 3GS iOS 4.1. In this guide you’ll learn how to jailbreak iPhone 4, 3GS running iOS 4.1 with Greenpois0n jailbreak. Greenpois0n is available for both Windows and Mac OS X.


IMPORTANT

iPhone users: Installing iOS 4.1 on your iPhone 4 or 3GS will updated its baseband which is not unlockable ATM. So, if you depend on unlock you’re strongly advised not to go for Greepois0n or Limera1n and also avoid iOS 4.1. Wait for the PwnageTool update which will be anytime now.

However, iPhone 4 users can still update to iOS 4.1 without updating baseband using Tinyumbrella. Here is how to: update iPhone 4 to iOS 4.1 without updating baseband.

Disclaimer: This guide is for educational and information purposes only. Follow the steps below at your own risk. We cannot be held responsible if anything goes wrong.

Lets jailbreak iPhone 4 iOS 4.1 and jailbreak iPhone 3GS iOS 4.1 using Greenpois0n jailbreak.

How to Jailbreak iPhone 4, 3GS with Greenpois0n

Step 1

Download the required stuff:

Step 2

iPhone 4: If you don’t need to unlock iPhone, simply update to iOS 4.1 via iTunes. But If you depend on unlock, follow the guide linked below to update your iPhone 4 to iOS 4.1 without upgrading its baseband:

How to Update iPhone 4 to iOS 4.1 without updating baseband

iPhone 3GS: If you don’t need to unlock iPhone 3GS, simply update to iOS 4.1 via iTunes. But If you depend on unlock, AVOID iOS 4.1, Greepois0n, Limera1n and wait for the PwnageTool to come out (hopefully within a week.)

Step 3

Connect your iPhone 4 / 3GS to your computer and turn it off.

Step 4

Now execute the downloaded Greenpois0n jailbreak (from step 1).

Step 5

Now hit the “Prepare to Jailbreak (DFU)” button on the Greepois0n and follow the on screen instructions to put your iPhone 4 / 3GS into DFU mode.

* If you find on screen instructions difficult to follow, we have an easy guide to: put iPhone into DFU Mode.
* If you think your device is in DFU mode but Greenpois0n is not detecting it, hit the “Prepare to Jailbreak (DFU)” button again.

Step 6

Once you’re into DFU mode, Greepois0n will tell you that your device is ready to jailbreak.

Hit the “Jailbreak!” button and Greenpois0n will start jailbreaking your iPhone 4 or iPhone 3GS.

Step 7

Once the process is successfully completed, Quit button will appear on Greenpois0n window.

That’s it. Check for the Cydia icon on your iPhone home screen. Have fun with your jailbroken iPhone 4/3GS on iOS 4.1. Don’t forget to share your experience in the comments section.

If Greenpois0n, due to any reason, doesn’t work for you, you can always use Limera1n:

After the jailbreak on iOS 4.1 with a preserved baseband, you can install UltraSn0w to unlock your iPhone. Follow the guide linked below to unlock your iPhone:

Trying to jailbreak my iPhone 4 iOS 4.1 with greenpois0n. Tried it 2 times. Loader icon is not appearing on Home screen.

Yelland October 12, 2010, 8:58 pm

Has the mac problem
Been fixed?

JazzytheMudkip October 13, 2010, 2:01 am

Does this work on iTouch 2G? ):

vodanhz October 13, 2010, 6:13 am

it goes into terminal run some upgrade etc…
once its done. it show up a white icon loader.
install Cydia. it says not enough space (i have just restore.so got 29gb free???)
can’t re-install cydia.
enter Cydia, it crash.

note: cydia also has a white icon.

am i missing something?

azhar October 13, 2010, 6:52 am

u should restart

DEV October 13, 2010, 7:13 am

reset your network on iphone if restart iphone you still have a white icon.
good luck

vodanhz October 13, 2010, 8:39 am

all i see is Loader, not Cydia.
should i download Cydia?

vodanhz October 13, 2010, 8:50 am

doesn’t work. 🙁

all i get is Loader (white icon). restart. reset network. seem to be the same.

when i download/install cydia.it say not enough disk space…

anyone got the same problem?

iPhoneHeat October 13, 2010, 11:51 pm

inside the loader, there is Cydia

tony October 13, 2010, 3:09 pm

get exactly the same problem as you!
What should I do now?

Fauzan October 21, 2010, 12:54 pm

Just use ifunbox,,you can google it and download the new version.. Go to “Application (System)” and delete cydia.app folder.. Then start the Loader again,and install cydia again will now work,..
I had the same problem,it should fix your problem..

kalbo February 18, 2011, 6:46 am

sorry, you should put your idevices in freezer and wait for update.

azhar October 13, 2010, 11:06 am

ouchhhh that really hurt when it will come out

aap4452 October 13, 2010, 6:58 am

Baseband: 02.10.04 – ICE_2_8 can jailbreak with GP?

Yelland October 13, 2010, 12:19 pm

Why isnt the mac link working??

Rodrigo October 13, 2010, 11:10 pm

Hi.

I´m having trouble downgrading my locked Iphone from ios 4.0.2 to 4.0.1.

Could I solve this problem more easily upgrading to iOs 4.1 keeping the baseband, jailbreaking with Greenpois0n and finally unlocking it 4 with UltraSn0w?

Thanks for the help!

ha3f October 14, 2010, 4:53 am

both Limera1n and Greenpois0n are great,,,,but which is the best for 3GS 4.1 05.14.02 unlocked factory? any idea??

Ryanu October 16, 2010, 1:24 pm

No unlock for 3GS yet…

stdjmax November 18, 2010, 6:17 pm

which is the best for 3GS BB 05.14.02 (new bootloader)?

vodanhz October 14, 2010, 5:19 am

anyone having problem where GP says not enough disk space?

TheGrid October 14, 2010, 1:55 pm

GP gives me “not enough disk space” after it completes the Cydia download. I’ve tried reset of network and severial attempts of GP re-install but no luck. I’m on a iPhone 3GS with baseband 05.14.02 iOS 4.1. Yes I’m one of those stuck on the iOS4.1 until an unlock is avail.

Limera1e works fine for me, but GP no luck.

iPhoneHeat October 14, 2010, 5:44 pm

Limera1n is also ok 🙂

vodanhz October 15, 2010, 3:45 am

funny thing was, one time limera1n works the instance i put to DFU when limera1n just run. it show up the lime drop.

after that, i did another restore to see if the method is actually work. and it failed. after about 5-6 tries, it didn’t work. so i ran GP, and this time, download and successfully installed, no “disk space” error,

hopefully a more stable version comes out for both limera1n / Greenpois0n.

ta 🙂

R0BB13 October 14, 2010, 9:11 am

is there any jailbreak or unlocks for 4.0.2 uphone 3gs?

iPhoneHeat October 14, 2010, 5:41 pm

use Limera1n

peter October 16, 2010, 2:18 am

This has not been working for my 3Gs with 4.02: limera1n says that it is jailbroken, but there is no icon; greenpois0n says “jailbreak failed”. I have tried both numerous time – no success.

iPhoneHeat October 16, 2010, 2:42 pm

keep retrying with Limera1n

Wakaas October 16, 2010, 2:53 pm

Open iTunes. Connect ur device. Open limera1n. Don’t close iTunes. Make it rain and follow instructions. U will succeed.

QO October 15, 2010, 1:20 am

Just looking for clarification. I have an IPhone 3GS, os 4.1, bb 5.14.02 & am using a mac for jailbreaking. I have to use green poison (when the mac link is enabled) because Limerain is only for windows to jailbreak. Then I have to wait for either the new pwnagtool, or for a software to pair w/greenpoison to unlock b/c ultrasnow isn’t for my baseband. Is all that correct or is there something I can use now? Also I can’t seem to get my phone into DFU mode.

iPhoneHeat October 15, 2010, 3:54 am

you cannot unlock even after PwnagTool because you baseband is already updated.. Limera1n for mac is out.. You can jailbreak right away but will have to wait for the ultraSn0w update

Zigen October 15, 2010, 4:42 pm

hail chronic dev-team! i was able to jailbreak my iphone 3GS 4.1/ 5.14.02. at first i was using laptop running on windows xp. i kept on having a ” quit” “try again” result. i did try on a windows vista. finally got a successful jailbreak! 🙂 just wondering why can’t i jailbreak on xp? any minimum system requirements? thanks chronic dev-team! 🙂

Naushad October 16, 2010, 5:54 pm

i am on iphone 3gs 4.0.1 05.11.07 new bootrom.
i was anxious to know that greenpoison or limerain is untethered jailbreak?
and if i update not from itune and use green poison my baseband will not update…and i can unlock through ultrasnow??

iPhoneHeat October 16, 2010, 10:15 pm

wait for PwnageTool if you depend on unlock

stupid3G October 17, 2010, 12:43 am

Does Green Poisi0n work on a 3G with 4.01 or just 3Gs and above? I tried to go into DFU endlessly!!!! No Worky….

Nafees Mansoor October 17, 2010, 1:11 am

Hi,
I got an already unlocked iphone4g from apple store..it is running iOS4.1 baseband 02.10.04
what i’d like to know is if I can jailbreak and still preserve the unlock from apple..I hope the jailbreak doesnt result in my phone getting locked? Thank you.

sowat99 October 25, 2010, 1:53 pm

@iphone_heat @iphoneheat hi I just newly bought my iphone4. It came with the 4.1 ios. I would like to jailbreak it using GP. but was wondering if GP is compatible with windows7 64-bit? Please reply thanks..

sowat99 October 27, 2010, 2:40 am

@iphone_heat #iphone_heat its okay you did not reply.. I jailbroke my iphone 4 using these informations:
Windows Vista 32bit OS
itunes 9.2
Green Poison.

Followed your guide, successfully got into DFU Mode, but most of the time Jailbreak Failed 🙁

So what I did was whent it was in DFU mode, I only released the sleep button and kept holding the home button while pressing Jailbreak it. Just keep holding the home butto, you will see the whole screen go white just keep holding the home button, then you will see the itunes cable, just keep holding the home button, then you will see now the texts booting up in your screen, you can now let go of the home button, then voila you are jailbroken. Hope this could help anyone who is in need of green poison..

I try with GP. all work well until I try to install cydia from
the loader.

It download the Cydia then install it, but all I got is White icon cydia (not chocolate one).Try to launch it and failed.Try to re-boot and still have the same problem.
