redsn0w

redsn0w is a free iOS jailbreaking tool developed by the iPhone Dev Team, capable of executing jailbreaks on many iOS devices by using low-level boot ROM exploits and additional exploits. It is a desktop application that enables users to jailbreak an iOS device (connected to the desktop computer with a standard USB charging cable) by clicking a series of buttons.

Over the time, DevTeam has implemented new features in redsn0w that allows users to put device into DFU mode, tether boot, preserve the iPhone baseband, fix recovery mode, fetch SHSH blobs and and much more.

The redsn0w jailbreak tutorial:

Using redsn0w is quite simple, all you need is an iDevice with a jailbreakable iOS version (supported by redsn0w) and you’re good to go. From the main window, select the Jailbreak option and follow the on screen instructions for every step. Please note that this tutorial is a general tutorial. Some options may vary depending on your iDevice – some may need to enter DFU mode to perform the jailbreak, some may need a baseband preservation, etc.

Step 1:

Download the latest version of redsn0w from this link and save it in a folder named “Redsn0w” on your desktop.

Step 2:

Double click the redsn0w zip file and extract the application to the redsn0w folder and then launch the executable file. Windows users should run Redsn0w as ‘Administrator’ (right-click on the redsn0w exe and select ‘Run as an Administrator’).

Step 3:

After launching redsn0w, click on the jailbreak button. redsn0w will now begin the jailbreak process and will go through the following steps: Preparing, Processing and Finishing up.

Step 4:

Once the three steps are completed, redsn0w will inform you that the jailbreak was successfully installed. You will see Cydia installed on your second page of your homescreen.

Preserving the iPhone baseband with redsn0w

If you rely on an unlock and your iPhone’s current baseband version is unlockable, preserving it might be very useful if you want to install a newer iOS version. Newer versions of redsn0w are now capable of preserving your baseband, which was once a feature that was exclusive to the Dev Team’s PwnageTool jailbreak tool. See the video below of a quick tutorial:

 

How to put your device into DFU Mode

In order to jailbreak some iDevices, you need to learn how to reliably place it into DFU mode. DFU mode stands for Device Firmware Upgrade mode and getting your iDevice in it is really easy. Just follow these steps and you’ll manage to successfully enter DFU mode:

Step 1:

You’ll need to connect your iDevice to your PC / Mac.

Step 2:

Next, please hold the Home + Power buttons on your device simultaneously for exactly 10 seconds.

Step 3:

A bit tricky, but stay with us: release the power button but keep pressing the home button for another 10 seconds.

Step 4:

Release the home button, and your screen should stay completely black.
To check if your iDevice is really in DFU mode, open iTunes and see if it reports that it has detected an iPhone in recovery mode.

Exiting the DFU mode is quite easy also, just hold the home button and the power button for 10 seconds and then release both. If unsure, here’s a video tutorial on how to enter DFU mode:

 

How to tether boot using redsn0w

Tether Booting is the action of booting an iDevice that has been jailbroken using a tethered jailbreak. Unlike untethered jailbreaks, tethered jailbreaks require a tethered boot anytime you wish to reboot the device. The following video will show you how to properly thether boot your iDevice:
