I am currently running a jailbroken iPad 2 on iOS 5.0.1. I want to upgrade to iOS 5.1.1, but Apple has already released iOS 6 and stopped signing the previous version. I have my SHSH blobs and a stitched IPSW, but iTunes is not allowing the restore. What is the correct method to use these blobs to complete the upgrade?

To upgrade your iPad 2 to iOS 5.1.1 after Apple has stopped signing the firmware, you must use a tool like RedSn0w that can utilize your saved SHSH blobs. Since you are already on iOS 5.x and have your 5.1.1 blobs, you can use the Restore function within RedSn0w to perform a local restore. First, open RedSn0w and navigate to Extras, then Even More, and click on Restore. Click on IPSW and select the official iOS 5.1.1 firmware file for your iPad 2. RedSn0w will prompt you for your blobs. Click Local and select the SHSH blobs you have saved for iOS 5.1.1. Follow the on-screen instructions to put your device into Pwned DFU mode. RedSn0w will then use the blobs to stitch a temporary firmware and restore your device to 5.1.1. This process bypasses the Apple signing servers. If you encounter errors, ensure you are using a version of RedSn0w that supports iPad 2 restores, such as version 0.9.15b3.
