GreenPois0n iOS 4.1 Jailbreak: Problems on iPhone 4, iPod Touch?

By: Alan Ng | October 14, 2010 | 61 Comments

After delaying it’s intended 10/10/10 release, most of you will already be aware that the iOS 4.1 jailbreaking tool GreenPois0n is now available to download. We want to know if you are having any problems with your iPhone or iPod Touch after installing.

If you haven’t already downloaded GreenPois0n, you can try it out over at the official website here, although we wouldn’t recommend it to those who are seeking an unlock method on iOS 4.1 too.

GreenPois0n has been implemented with the Limera1n jailbreak by Geohot, which means that it now supports a variety of iOS 4.1 devices, not just the 4th gen iPhone 4 and iPod Touch as previously stated.

For those who have already installed GreenPois0n, is everything working fine or do you continue to have problems with the software? List your issues below so our other readers can help you out.

Hi I have a problem with my iPhone 4 4.1. I can’t enter dfu no matter how hard I try. I helped my other friends jb with green poison and so far so good. Is it possible that it is impossible to go into dfu mode?
Zack
I tried BOTH Limera1n and Greenpois0n, and neither of them worked. I did them on two different computers too, one running XP and one running Win7. Limera1n kept saying that the jailbreak was successful but on the phone after a restart it wasn't there. And Greenpois0n failed every time. BULL SHIT.

I installed green poisons jailbreak on my iphone 4 4.1 and have had not one issue with anything.
Cant wait until they come out with the unlock for the phone as well so it can be used on other carriers.

i tried limerain first and spent hours/days trying to get cydia icon to appear , but no joy !!!! viewed all the comments and watched you tube advice etc …. then when green poison came out had problems too , i have ipod touch 3g running 4.1 . in the end i restored ipod to factory settings and it worked first time!!! now jailbroken , just synch back to i tunes after j.b and you should be o.k !!! worth trying this because i tried everything else suggested and was on the verge of throwing the bloody thing thru the window !!!!

I jailbroke my ipod with green poison and it worked for a month or so and I updated to 4.3 and of course undoing the jail break but it didn't fully restore it says somethings wrong with my internal device. I'm new to Apple products but I have no idea what happened?!?
staceyausten
how did you restore the factory settings?

Econn98
Why would you download Greenp0ison? They kept playing around with you, didn’t tell anyone it wouldn’t work with older devices, then didn’t even deliver on their promise date????? Limera1n deserves all of the credit and gratitude, use them and their site. It’s better and Geohot deserves the traffic!

seyaad
put in and ran away nowhere to help the problem cause by limerain at least greenpoison team with dev team is there to answer

Luke wignall
Sorry but greenpoison is rubbish! Doesn’t even jailbreak most of the iPods? WTF let down much!
safcmad
I installed Greenpois0n and it has worked a treat. Easy to follow instructions and I’m not intending to unlock so this is perfect. Top notch!

I installed Limera1n on my iPhone 4 with OS 4.1 with modem firmware 02.10.04. After installation when I ran Limera1n it started fine but it could not find cydia. It was not able to download it from the internet though I could browse the internet using Safari. It kept saying check your internet connection. I tried at least 10 times even re-installing Limera1n did not help.
Yesterday I installed greenpois0n. It loads everything including Cydia. I ran cydia and it installed with out any errors. But my cellphone still does not recognise the SIM card.
Is my phone unlocked or not can somebody please help.
XmLo
I installed first Limera1n and it all was cool, except for some problems with the apps bought in iTunes, they didnt even work with my iPhone, and when i tried with GreenPoison the same happened, any1 know why??
Arianna
I believe I installed this correctly. Cydia is on my iPod touch. But when I go on to apptrackr.org, my safari is unable to download the files. Am I missing something? =(

If you used Limerain then reboot the use greenpoison. If u used greenpoison then rejailbreak with limewire. Worked for me. Also download the app "Palringo" on device or pc and join the group CHUMMPBREAK. IT A Jailbreaking and cydia help group.

JD
Used Greenpois0n. Easy to use and thought it was flawless until I tried to send an Mms. Keep getting an error message saying it’s unsuitable for the mms adaptation.

Just installed Greenpois0n on ipod touch 4g with 4.1…still needa run the loader but ill post back afterr i do
Fayalhd
Greenpoison slowed my iPod touch 4g down especially in games

jim aASD
this didn't happen due to greenpois0n….i would recommend you to delete some cydia apps you don't use, and some games(if you have a lot)…….this should speed up your ipod a little bit!

aa_36
i installed cydia and whiteboard after jailbreaking, but after i set the themes i still see no difference..

jim aASD
i have heard that whiteboard is not working on some ipods…try to download winterboard (it is far better than whiteboard) and download any theme you want..enable the theme, respring and if you don't get a positive result………then i don't have any other ideas!

I got iphone4 4.1 advice how to jailbreak bcos I tried both green poison n limera n my phone is factory unlockeD
JKT
Do not use GreenPois0n for Mac. Not only did it not jailbreak my phone after multiple attempts, it crashed the USB bus on my Mac, leaving it unusable so I had to force reboot it. Avoid!
Phillloyd
Used greenpois0n on 2 iPhone 4′s running 4.1 in the uk.

T-mobile version perfect, has facetime and mms running great.
3uk version runs great has facetime but no mms.

iPod Version- 3rd Generation 4.2.1.
I downloaded Cydia and then I tried to download Installous. It was taking soo long so I stopped it and started to re-download installous. But it keeps on showing the bar (when downloading) going all the way to the end, then nothing happens and the Installous icon doesn't pop up on my home screen. Help.

Ok, a few days ago I tried to reset my iPod Touch since I don't like it jailbroken… so I forgot I had to restore it by iTunes in order for it to take it off, so instead I went to Settings>General>Reset only on my iPod – it said it'd only take an hour… so an hour goes by and I see it is frozen were the greenp0ison skull is loading.
I try to connect it to my iTunes, but it doesn't make it to wear my iTunes can read the device, taking the opportunity to restore from my PC.
Please help, I have to idea what to try… I try to stop it by holding down the top and square button, but when I turn it on, it does that whole process ^^^ again
