If you would like, feel free to watch this tutorial in video form.
redsn0w is one of the longest running jailbreaking programs and is still going strong on it’s latest 0.9.8b3 release. redsn0w is a simple to use jailbreak that should take just a few minutes from start to finish to complete.
This is a tethered jailbreak for some devices on iOS 4.3.4 and iOS 4.3.5. As with all jailbreaks it is highly recommended that you connect your device to iTunes and let it sync to back up all of your data. You should not lose any data in the jailbreak but there’s always a chance that something could go wrong so it’s always a good idea to be safe.
To start with you will need to download redsn0w 0.9.8b3 for either Windows or Mac.
These screenshots were taken using redsn0w 0.9.6rc15 however the process remains the same in 0.9.8b3.
If you are on a Windows Vista or Windows 7 computer there is one additional step. Right click on redsn0w.exe and then click Properties. Select the Compatibility tab and here you’ll need to do two things. First check ‘Run this program in compatibility mode’ for Windows XP Service Pack 3. If you don’t see an option for Service Pack 3 try Service Pack 2 or Windows 2000. Next check ‘Run this program as an Administrator’. Apply the changes.
At this point you are going to need to locate the 4.3.4 IPSW firmware file (even if you are jailbreaking on 4.3.5) for your device. If you are unsure where the firmware file is on your computer click here to learn how to find it. Once you have found the firmware direct redsn0w toward it and give it a moment to process.
At this point redsn0w will ask you to select your options. The most important thing is to keep the Install Cydia option checked, everything else is up to you. Not all options are available on all devices however so let me briefly explain what each does.
- Install Cydia – Installs Cydia, the main package installer for jailbroken devices
- Install custom bundle – Allows you to install a custom bundle
- Enable battery percentage – Enables the numeric battery percentage
- Enable multitask gestures – Enables the use of four or five finger gestures to control multitasking
- Just boot tethered right now – You will need to use this to boot your device every time (including after the jailbreak)
- Just enter pwned DFU mode right now – Allows you to immediately enter a pwned DFU mode state
Once you have selected the options you would like, click Next.
At this point you are ready to begin the jailbreak. Plug your device into the computer and then hold the Sleep button until you get ‘Slide to Power Off’. Shut off your device.
At this point you need to put your device into DFU mode. It’s a simple process and redsn0w will walk you through it. If you drop a button or mistime something just let your device boot normally and try again.
Once you successfully enter DFU mode then give your device a few moments to let the jailbreak run. Your device should display that it is downloading jailbreak data then start displaying lines of code. When it is done your device should look just like before the jailbreak with the addition of a white Cydia icon.
Open redsn0w again and do the same process as before until you get to this screen. Instead of rejailbreaking however at the option select screen instead choose ‘Just boot tethered right now’. Enter DFU mode like before and give your device a few minutes to boot up.
Now on your device you should see a normal Cydia icon on your SpringBoard. Congratulations, you are now jailbroken!
