Previously, we posted a tutorial on how to jailbreak your A5 devices untethered with the non-DFU method using the Redsn0w tool to on iOS 5.1.1. This time however, we are going to go through jailbreaking untethered 5.1.1 using the DFU mode (Device Firmware Update) using Redsn0w 0.9.12b2. This method can only be used on A4 devices (referring to the processor), the non-DFU method can be used for A5 devices only as iPhone 4S and the new iPad.
Although the non-DFU method is preferred most of the times, it’s advisable to use the old school DFU method for people who have a lot of data on their A4 devices. In addition to that, it works better with iCloud. The non-DFU method has issues with iCloud syncing and some how those issues aren’t there when you jailbreak using the DFU method.
Jailbreak your A4 iOS device on iOS 5.1.1 untethered
Step 1: Connect your A4 device to PC.
Step 2: Connect it with iTunes.
Step 3: With the device turned off, hold the Power and Home button together for around 10 seconds, and release the Power button but keep on holding the home button until iTunes tells you that your device has been detected.
Step 5: Click on the Jailbreak button.
Step 6: In the options menu check install Cydia and click on Next.
Step 7: Once you are on your lockscreen just unlock it and run Cydia.
Be sure you follow these instructions as they are, if you face any problems don’t worry there is always a way around it, even if you end up messing up with the iOS. That’s all to it, nothing complicated just a couple of easy steps and your device will be jailbroken. Be sure to comment and tell us about any problems you faced or if this method was better than the previous one.If you found this post useful, hopefully share the word!
