While I talked about jailbreaking iOS 4.3.4 using RedSn0w on my last topic, I assumed that everyone knows already how to jailbreak an iDevice using RedSn0w. For those who don’t, here is a step-by-step guide on how to do it. Once again, I would like to remind everyone that if you are running iOS 4.3.3 right now, DO NOT upgrade anymore to iOS 4.3.4. This is because you do not need RedSn0w to jailbreak your iPhone 4. Better use JailbreakME 3.0 for a fast and easy jailbreak.
This is a general procedure dedicated for someone who was stuck on iOS 4.3.4 that still wants to jailbreak (excluding iPad 2). The result would be a TETHERED jailbreak. Meaning, you will have to jailbreak again every time your iPhone is rebooted. Better than nothing.
First of all, always update your iTunes to the latest version. Make sure that your device is in iOS 4.3.3 or 4.3.4. If not, update first through iTunes to achieve iOS 4.3.4.
- Download the latest RedSn0w 0.9.8b3 and iOS 4.3.4 and save it in a folder easy for you to find (best on your desktop).
- Unzip RedSnow and launch .exe file. If you are using Windows 7 or Vista, this is an additional step. You need to right click the .exe file and select for the compatibility tab. First, check “Run this program in compatibility mode” for Windows XP Service Pack 3. Next, check also “Run this program as an Administrator” and Apply the changes.
- Browse for the firmware you had just downloaded.
- RedSn0w will prepare to jailbreak your iPhone. Wait for a few seconds. Select “Cydia” to be included in the installation.
- Turn off your iPhone and make sure it is connected to the computer. To continue, click “Next”.
- Follow the onscreen instructions to get your iPhone in DFU mode. You will have to press the Home and Power buttons in this procedure. Make sure to follow.
- If you had successfully turned your iPhone in DFU mode, RedSn0w will now start to inject the jailbreak process in your iPhone. Wait for RedSnow to do the job and it should be done in a couple of minutes.
- Your iPhone will reboot once the process is completed. Cydia icon will now be present in your iPhone.
Congratulations on your newly jailbroken iPhone 4!
