I have TinyUmbrella and it says i have the SHSH ipad2wifi 4.3.3 When i click the TSS server button it doesn't connect. I tried 'restore' through itunes and let it backup my ipad but it popped up an error message at end of process. I want to get rid of JB and just have a clean ipad and update to the latest iOS. How can I do that? Thanks.
