iOS 5.1 untethered jailbreak using Redsn0w 0.9.10b6

How to Jailbreak iOS 5.1 with Redsn0w 0.9.10b6

Finally iOS 5.1 has been dropped, and we recommend everyone to stay away from such update if you really care about your jail broken device, as recommended by the iPhone Dev Team.

Device which runs on A4 chip or older can still enjoy this benefit by doing tethered jailbreak on iOS 5.1 and can degrade back to earlier firmware if you have Signature HaSH blob (SHSH) for those firmware.  Whereas for devices which runs on A5 chip like iPhone 4S and iPad 2, it is not possible to degrade back to older iOS 5.x firmware even if you have SHSH blob stored.  So don’t upgrade to iOS 5.1 if you care about your Jail Broken iPhone 4S.

Here is a nice tutorial about how to carry out a tethered jailbreak on iOS 5.1 for devices which runs on A4 chip or older like:

  • iPhone 4
  • iPhone 3GS
  • Original iPad
  • iPod touch

iOS 5.1 untethered jailbreak using Redsn0w 0.9.10b6

Step 1: Download RedSn0w 0.9.10b6 from Here and execute it.

Mac: sites.google.com/a/iphone-dev.com/files/home/redsn0w_mac_0.9.10b6b.zip?attredirects=0&d=1

Windows: sites.google.com/a/iphone-dev.com/files/home/redsn0w_mac_0.9.10b6b.zip?attredirects=0&d=1

Step 2: Keep your A4 device on DFU (Device Firmware Update) mode.

Step 3: Once Redsn0w gets executed click on jailbreak, it will start scanning and a pop up appears asking you to Jailbreak and install Cydia. Click on Jailbreak option and click next

Step 4: As mentioned above… Don’t try it on device which runs on A5 Chip.  Click on Next

Step 5: Installation of Cydia will start and once done it will take you to the Home screen wherein you will find Cydia App Installed and the icon in white block which shows that the installation is yet to complete.  So to complete the installation successfully we need to do a tethered reboot.

Step 6: Get your device back to DFU mode.

Step 7: Run Redsn0w and you will find a screen similar to the image below, just click on Just Boot and the device will start tethered rebooting.  At the end it will take you to the home screen, now you can see the Cydia icon properly displayed which shows that the installation is complete so is the jail breaking process.

The main drawback in here is that each time we reboot our device we will have to follow the last two steps.

So it’s all your call now whether to jailbreak or not but our suggestion is to do it only if you have a device which runs on A4 chips or older.
