How to Jailbreak an iPod Touch 4.2.1

Last Updated: June 4, 2020

Many people are beginning to jailbreak their iPods and iPhones, which means that once they've jailbroken their device they can get any app for free. I'm going to tell you how to jailbreak your Version 4.2.1 iPod Touch.

Steps

1
Confirm that the iPod you have is in fact Version 4.2.1. You can do this by unlocking your device and clicking Settings on the front page. You then tap on General and go to About. Scroll down until you find version and beside it, the number of the version that you own. If it is 4.2.1 then the following instructions will work for your iPod.
2
Go to www.greenpois0n.com which is a jailbreaking website that is known to be the easiest way to get the job done. Click on the downloads tab at the top of the page and scroll down a bit; you will find "Jail Firmware 4.2.1" and right underneath that there will be two choices. You will click the second one that says "greenpois0n RC6.1 (win)" and install it.

A box will pop up that has the options, one that says Greenpois0n and then right under something that says README. Click Greenpois0n and then ANOTHER box will come up that says "Prepare to Jailbreak." Click that but first make sure you have your iPod already plugged into the USB of your computer.
4
It will have 4 simple steps that you follow within the amount of seconds given. It will say "Get Ready to Start," "Hold down on sleep button," "Continue to hold down on sleep button but hold down on home button as well," and "Release sleep button but continue to hold down on home button." If you followed the directions successfully then a button underneath will say "Jailbreak" and you can click that.
5
After the jailbreak has been completed your iPod should flash white and then turn black and display a bunch of white letters across the screen. Wait for this to finish and then after the Apple symbol should appear, proceeded by the jailbreak sign, which is a picture of a skull.
6
Go to Loader after your device has finished loading and tap "Install Cydia." This is where you go to download Installous, which is where you can get your apps from.
7
After Cydia has been installed, open it up and on the bottom there will be some buttons, tap on Manage. Tap Sources. At the top right, tap Edit. At the top left, tap Add. In the box, write http://cydia.hackulo.us/ After, you tap Add Source. Let it load, and the under the Entered by User section, click the link that says Hackulo.us. Scroll down until you see Installous, which is where you can get all of the good apps.
8
Open Installous, which should now be downloaded onto your iPod in the area where your other applications are.
9
From here you can browse apps and find ones you like or search them up. If you see an app you would like to get, then just open it up and click Download. From here there will be a bunch of links, and usually the very first one works, but if it doesn't scroll down to the last one and see if that works. If a new page opens, then you know it is working. Click "Start Download" and from there you should know what to do.

Question

What should I do if my power button is broken?

Community Answer

Set your auto-lock on 30 seconds and wait for it to turn off. You can find auto-lock in settings under "General" or "Brightness."
Question

Are there any other sites available?

Yes, if you look at an online search engine.

Warnings

Jailbreaking any Apple device immediately voids the warranty, which means any damages won't be covered anymore.
