Hey guys! I'm currently on 7.0.4. I want to do a factory restore on it. Since it is jail-broken I can't do it through settings. I've tried upgrading it to 7.1.2 and 8.1.2 by using TinyUmbrella v7.1.2 . But it gets stuck on "Preparing iPad for Restore". How can I factory reset my device or upgrade it to a version which is currently jailbreak-able? Any help would be highly appreciated. Thanks.
