So here's my situation. I have a jailbroken ipad2 on 5.0.1 and I want to upage to 5.1.1 and re-jailbreak after restoring. Here's the issue. Apple is no longer signing the 5.1.1 update, but according to my cydia app on my ipad, cydia has saved my 5.1.1 shsh blob even though I have never updated to that version of ios. How do I go about upgrading to 5.1.1 and not ios 6? I'm assuming I need to use Tinyumbrella? Please point me in the right direction. I've searched, but haven't found my specific situation.
