So now that we have defined Jailbreaking, we should be just about ready to begin. Oh yes, and one more thing, the requirements. You will need to download a few files before starting this tutorial:
Your iDevice's firmware, which can be found here:
http://www.felixbruns.de/iPod/firmware/ ***(Don't Download It Just Yet Though)***
Redsn0w http://blog.iphone-dev.org/tagged/redsn0w ***(This is for iOS 4.3.5 and below!)***
Redsn0w http://blog.iphone-dev.org/redsn0w-iOS5 ***(This is for iOS 5 and above!)***
Please Note: If you can't find the Redsn0w download links on the site, then scroll all the way down to where the comments begin, and look above that. The download link should be somewhere there.
Ok, If we have everything prepared, we can begin:
• Step 1: Plug in your iDevice, and then turn it off. It is important you do it in this order, because if your turn it off first, then your iDevice will boot as soon as you plug it in.
• Step 2: Open Redsn0w. (If you are going to jailbreak iOS 5 and above please skip steps 3 and 4)
• Step 3: Download the firmware file that your iDevice is currently on, or if you already have it on your computer, hit the browse button and look for it. The extension should be .ipsw.
• Step 4: Now, click next and select what you want to install. Keep Cydia ticked, because it is the whole point of jailbreaking.
• Step 5: Click next again and follow the steps to put your iDevice into DFU (Device Firmware Update) mode.
• Step 6: Redsn0w will now begin to jailbreak your iDevice.
• Step 7: After it has finished jailbreaking, and after it has finally rebooted, you are done! If Cydia has a white logo, or safari crashes, then you have a tethered jailbreak, meaning that every time you turn off the iDevice, you MUST boot it tethered. This means doing steps 1-4 again, BUT, in step 4 do not tick anything other than "Just Boot Tethered Right Now". Then follow Redsn0w from there.
***PLEASE READ IF YOU ARE HAVING TROUBLE JAILBREAKING IOS 5***
If you are having trouble, you should download the firmware file of iOS 5, that's right, just 5, to your computer for your device, and then quit Redsn0w and start it up again. On the home screen there should be something called Extras, and from there it will say select ipsw. Select the firmware you just downloaded and it will say you are going to use this firmware. After that, go back to the home screen and jailbreak like that. This is a tethered jailbreak by the way, so please read step 7 for information on this.
Alright, if everything is cleared up and you have Cydia up and running on your iDevice, then you are finished! Thanks for reading this tutorial and I hope you enjoy your jailbroken iPod, iPhone or iPod Touch!
