How to Jailbreak iOS 5.1 with Redsn0w [Tethered]
A version of Redsn0w has been released to jailbreak iOS 5.1 tethered. While easy to do and easy to reverse, be sure to understand the difference between a tethered and untethered jailbreak. Put simply, tethered means the device must be connected to a computer to boot properly and become usable. Some consider this annoying and therefore it is not always recommended.
- Compatible with: iPhone 3GS, iPhone 4 CDMA & GSM, iPod touch 2nd, 3rd, & 4th gen, iPad 1
- Download iOS 5.1 and update if you haven’t done so already
- Download Redsn0w 0.9.10b6, Mac & Windows versions are available
Notice that iPhone 4S, iPad 2, and iPad 3 are not supported by this jailbreak.
Jailbreak iOS 5.1 Tethered with Redsn0w
- Turn the iPhone, iPad, or iPod touch OFF
- Connect the iOS device to the computer using the power cable
- Launch Redsn0w (run as Admin from Windows)
- Put the device into DFU mode: hold the Power button and home button together for 10 seconds, then release the Power button while continuing to hold Home for another 10 seconds
- Click “Jailbreak” in Redsn0w to start the jailbreaking process and click “Next” when asked, you’ll see some console gibberish appear on the screen and when finished you’ll be back at the iOS home screen
- Now you must boot tethered, put the iOS device back into DFU mode (hold Power button & home button for 10 seconds, release Power and hold Home for 10 more seconds) and launch Redsn0w again, click on “Extras” and click on on “Just Boot”
- When the iOS device boots, it will be fully usable
Every time the iPhone, iPad, or iPod touch is turned on or off it will need to be booted using the Redsn0w tether. This means if the battery dies or the device is rebooted for any reason, you will need to connect the iOS device to a computer running Redsn0w and choose the same “Boot Tethered” option from the Extras menu. If you jailbreak and have the white Cydia icon this means you did not perform a tethered boot, launch redsn0w and do so to resolve that.
Currently iBooks does not work either, if you’re in the midst of reading a page turning novel you may want to avoid this jailbreak for the time being.
