Hi all, I have a question that I just can't get sorted out. I have an iPad 1 and I want to restore it to iOS 3 or 4. Why? Because it will be way faster and I do not need any function that is iOS 5-only. I only have the SHSH Blobs of iOS 5.1.1. The Internet tells me I can do this, but I keep getting errors and I just don't know what to do anymore. So, now I am here and I hope to get some advice. What I did: I saved my SHSH blobs from iOS 5.1.1. Then I modified those blobs with Bluefreeze to use them with iOS 4.2.1. Then I stitched the blobs into an iOS 4.2.1 IPSW using Sn0wbreeze. Next, I put the iPad into pwned DFU mode and tried to install the modified IPSW with iTunes. This seemed to work until the very end, but then I got the iTunes error 37. I tried modifying my host file every possible way, I tried to run a SSH server, I tried different cable, I tried everything I knew, but I keep getting the error. I tried every possible solution to solve this error, but no luck. So currently, I am stuck at this. Does anyone know what to do now? Can I install iOS 3 or 4 without blobs? The Internet says so, but only from iOS 5.1.1 to 5.0.1 and that is not my goal. Is there anyone that knows what to do now? Anyone that knows more about this than me? I am out of ideas. Thanks in advance. PS. If this is in the wrong section, I request this thread be moved to the correct section by a moderator. Thanks.
