Jailbreak iPod Touch 4.2.1 with GreenPois0n on Windows

Recently, I got iPod Touch and like any other Apple Device owner wanted to jailbreak it to remove restrictions and install unsigned / cracked apps. So, I selected GreenPois0n to jailbreak my iPod touch 4G with iOS 4.2.1 and here we go with the procedure.

1. Download GreenPois0n – RC 6 is latest at the moment.

2. Power Off iPod and connect it via USB.

3. Launch the GreenPois0n.exe and to put your device into DFU mode, follow procedure with timings.

* Press and hold the sleep button for 2 seconds
* While holding Sleep button, press and hold Home button for 10 seconds
* Release the Sleep button but continue holding Home button for 15 second

4. Press on Jailbreak as soon as it detects your device in DFU Mode when it is ready to Jailbreak.

5. GreenPois0n will start jailbreaking your device and Soon, your device will show something like Boot Screen. Wait till the Tool says Jailbreak Completed.

iPod will restart itself and you’ll notice that boot logo is no more the apple logo. It means Jailbreak successful.

On Homescreen, there will be an icon named Loader from where you can install Cydia.

After installing Cydia, you can opt for adding Sources to get Installous that allows to install cracked apps.

i did all of this, but when the skull comes up, it wont change. it doesnt go to the home screen and im stuck. what do i do?

    Rohit Langde - April 4, 2011

    You mean iPod hangs on the screen when skull appears. In that case, restart the GreenPois0n application and repeat the procedure by reconnecting the USB cable.

    I had to repeat all steps when Jailbreak didn’t happen even though application showed it successful.

    Rohit Langde - April 6, 2011

    I didn’t get your question.
    Do you mean Restart or Start after Jailbreak? Which Boot Logo is being shown- Apple or Skull?

Tedde - April 11, 2011

I have tried several times and always gets stuck on skull screen. What can i do. reply

cking - April 11, 2011

son did this to his itouch. when you go to turn it on it does the apple screen then switches to the skull screen and stays there. Nothing. When i plug it into itunes, nothing. When i hold the power and circle button down to restart, we just do it all over again.
is there a solution or is it screwed.? Does this also void any warranty?

mick - April 14, 2011

Katrina - December 20, 2011

I need help with my iPod touch (4th generation) running firmware version 4.2.1. I followed the steps above, but it never fully completes. It gets stuck after it states the jailbreak is complete, but it never goes to the reboot stage to power off and install cydia. It shuts down after a few minutes then shows a picture of iTunes logo and the connector. What does this mean? please help!

Katrina - December 20, 2011

by they way I have tried this like 5x’s and it says no firmware found. very confused. I was giving this Ipod touch by a friend who upgraded..now I wonder why…

adiel - January 13, 2012

i did all all and it worked but there was not a icon named loader and i couldn’t find cydia

David - February 29, 2012

It’s really late to ask but ON my ipod touch (version 4.2.1). After I dowloaded the file from my computer, it tells me to follow the steps like first turn off the the ipod touch, then hold the sleep button for 2 secs and then without releasing the sleep button hold the home button for 10 secs and then releases the sleep button and hold the home button for 15 secs. BUT MY PROBLEM IS..I CAN’T SEEM TO GET MY IPOD INTO DFU MODE, I’d retry the steps a BILLION times but it never works. Pease HELP!!!
