Apple has just released download iOS 5.1.1 IPSW update for all iDevice owners along with the next-generation iPad Retina display tablet with pre-installed iOS 5.1. Producing and pushing out the update to its mobile operating system, taking the latest version of 5.1.1, which offers some additional features, bug fixes and security patches though, its also serves to keep the jailbreak development team live and forcing them to roll out an update to perform an untethered or tethered jailbreak tools.
Its confirmed by several sources that the current latest version of Redsn0w jailbreaking tool can be used to jailbreak Apple’s latest iOS update a tethered on A4 powered devices such as the iPhone 4, iPad 1, iPod touch 4G and 3G, as well as allowing them to continue the access to all the advantages of a liberated iOS device.
The iPhone Dev Team member and developer MuscleNerd has confirmed that Redsn0w can jailbreak 5.1.1 iOS on non-A5 devices to make tethered. Here’s what you looking for, a complete step-by-step guide on jailbreaking your iPhone, iPad and iPod touch on iOS 5.1.1 using Redsn0w.
How To Jailbreak iOS 5.1.1 Using Redsn0w
Step 1: Download latest version of the iPhone Dev Team’s Redsn0w tool for your operating system PC (Windows / Mac).
Step 2: Before get started, you are adviced to make a backup all the content of your device by connecting iOS device to iTunes and perform it, or you can opt back up the device to iCloud if enabled using this alternative method.
Step 3: After backup completes, upgrade your device’s firmware to iOS 5.1.1. This can be done either via OTA update on your device, or by simply pugging in the device onto your PC or Mac, launching iTunes and accepting and installing the update, or by downloading the iOS 5.1.1 direct links (device-specific firmware file) and manually update/install via iTunes.
Step 4: Download iOS 5.1 (not iOS 5.1.1) IPSW file that suited for the specific device you are using.
Step 5: Locate downloaded Redsnow folder from step 1, unzip the contents and run the executable file to launch Redsn0w.
Step 6: Select ‘Extras’ on Redsn0w GUI and choose the “select IPSW’ option.
Step 7: When prompted, point to IPSW file wich you grabbed from step 4 (the iOS 5.1) and select it.
Step 8: Now go to the main home screen of Redsn0w, select “jailbreak” and then click on next, then when asked, and make sure to select “Install Cydia” option before preceeding.
Step 9: You will now have to put the device into DFU mode. This is a must required process for the jailbreak to be successfully jailbroken. So, make sure to follow all steps carefully.
Step 10: When iDevice in DFU mode (detected), Redsn0w will automatically set all the rest of the process before finishing off on the device. Don’t panic, when the procedure starts you’ll see entirely white lines of text scrolling down the device’s screen. After completion, the device revboots, the jailbreak process is complete which should be witness by the presence of Cydia icon sitting on the iOS device home screen.
Note: This isn’t an untethered jailbreak, but a tether one, so you’ll need to boot your device into tethered boot mode on every restart or reboot. Simply by launching Redsn0w, select “Extras”, then “just boot” in order to boot your device tethered, which is a bit time wasting.
I prefer to wait for the untethered iOS 5.1.1 jailbreak so that it can be automatically done without needing to re-connect to the Redsn0w jailbreak tool to boot device tethered.
