Jailbreak iOS 5.0.1 with Redsn0w 0.9.9b8

iOS 5.0.1 Beta has been seeded to developers, starting yesterday. This update fixes the notorious iPhone 4S battery drain issue that has been causing sleepless nights to Apple engineers. Apart from this, it also fixes a security hole related to the iPad 2 smart cover and brings the much desired multitasking gestures to iPad 1.

The gestures let you easily return to the Homescreen by pinching and switch between running apps by swiping left or right. We have already shown you how you can enable these gestures on iPad 1 without jailbreaking, but you no longer need this tweak once you update to iOS 5.0.1.

Note that iOS 5.0.1 is currently in Beta and is available for download for only Apple registered developers. Apple has not yet given the public release date, but going by their previous releases, we expect it to be out in the next week or so.

Redsn0w has now been updated to support iOS 5.0.1. The previous version of Redsn0w was also able to do the job. It, however, required you to point to iOS 5 IPSW in order to jailbreak iOS 5.0.1. This trick is no longer needed, as the iPhone Dev Team have added iOS 5.0.1 Beta keys to Redsn0w.

Here is how you can jailbreak iOS 5.0.1 on iPhone 4, iPhone 3GS, iPad 1, iPod Touch 4G/3G using Redsn0w 0.9.9b8. iPad 2 users will have to wait until a jailbreak for their device becomes publicly available. Note that this jailbreak is tethered for all supported devices, except the iPhone 3GS old bootrom, for which the jailbreak is untethered.

1. Download iOS 5.0.1 IPSW and update your iDevice to this latest firmware.

2. Download Redsn0w 0.9.9b8 for Windows or Mac OS X.

3. Launch Redsn0w and navigate to Extras –> Select IPSW.

4. Now browse and select iOS 5.0.1 firmware on your Computer.

5. Next go back to the main screen and click on ‘Jailbreak’.

6.On the following screen, make sure ‘Install Cydia’ is selected. Click ‘Next’.

7. Power OFF your iDevice and connect it to your Computer via USB cable.

8. Click ‘Next’ and follow the onscreen instructions to put your device into DFU mode.

A. Hold down the POWER button for 3 seconds.

B. Without releasing the POWER button, also hold down the HOME button for 10 seconds.

C. Without releasing the HOME button, release the POWER button BUT KEEP HOLDING the HOME button for around 15 seconds.

Your device should now be in DFU mode.

9. Redsn0w will now inject the Limera1n exploit and jailbreak your device.

Once your iPhone reboots, it will be jailbroken on iOS 5.0.1. Since this is a tethered jailbreak, you will need to run Redsn0w once again and use the Extras –> Just boot option to boot into tethered mode. Otherwise, Cydia and other jailbreak apps will not work.

You can also do a semi-tethered jailbreak of your iPhone or iPad using a Cydia app called SemiTether. Read our article on semi tethered jailbreak for iOS 5 to know what it is, and how to get it on your iDevice.
