Soon after Apple released iOS 5.1, we all heard that hackers warned users not to update their devices to iOS 5.1. Unfortunately, it seems not every user read the warning in time so now users on iOS 5.1 have lost their untethered jailbreak. Fortunately for owners of non-A5 devices (all devices except iPhone 4S and iPad 2), you can now semitether your device!
iPhone Dev Team released Redsn0w 0.9.10b6 for those Apple users who upgraded to iOS 5.1 but remember this is just a Tethered jailbreak not untethered one.. But also that’s not all also the BigBoss updated “SemiTether” jailbreak tweak to work on iOS 5.1. So before we began our little and easy guide there is a lot of important notes you should read it before entering the guide:
- This jailbreak is tethered jailbreak which means you’ll need to connect your device to computer everytime it reboots. You’ll need to do a tethered boot.
- If you rely on unlock, don’t follow this guide. We’ll post a guide shortly on how to preserve baseband and keep the unlock.
- The jailbreak is not meant for A5 devices, i.e. iPad 2, iPad 3 (“new iPad”) and iPhone 4S.
How To Tethered Jailbreak iOS 5.1 iPhone, iPad and iPod Touch Using Redsn0w 0.9.10b6 [Guide]
STEP 1: Download iTunes 10.6 for Windows/ Mac OS X, Download iOS 5.1 IPSW.
STEP 2: Download Redsn0w 0.9.10b6 Tethered jailbreak [Mac users][Windows users]
STEP 3: Now simply back up your iPhone and then restore your device using iOS 5.1 ipsw. (If you are already on iOS 5.1, just ignore this step and go to step 4)
STEP 4: Now open Redsn0w 0.9.10b6 from your desktop and press on “Jailbreak” button then “Install Cydia” and follow on-screen instructions to put your device into DFU mode.
STEP 5: Now you are having Redsn0w tethered jailbreak on your device which means every-time when you download a tweak or anything else you will have to launch Redsn0w, select “Extras” then”Just Boot” and put your device in DFU mode to get it rebooted and working.
STEP 6: This step is optional as instead of downloading Redsn0w and doing the steps above you have the ability to download a tweak called “Semi Tether” which can be found in Cydia store via BigBoss repo.. here’s the repo http://thebigboss.org/semitether.
