So I used Cydia Impactor and Yalu to jailbreak my iPhone 6s, which is in iOs 10.1. With this jailbreak when your iPhone dies or resets you will have all the jailbreak app icons on your page but you cannot access them unless you manually jailbreak it again through your computer. Here is the problem. (AND PLEASE READ THE EDITS BEFORE REPLYING) I am trying to update to iOs 11, however, when I try it says that there is an error, it says "Software Update Failed" and underneath it says "An error occurred downloading iOS 11.2.6". I only have 2 options to tap which are "Close" and "Settings". Both options take me back to the software update page. After this occurred I think that it is the jailbreak problem, I cannot access Cydia to uninstall jailbreak because I have to re-jailbreak it on my computer to access Cydia. When I plug my iPhone to my computer, and yes, I have tried every USB slot, and I have tried two different Apple Approved connectors (the ones that come in with your iPhone), my computer does not recognize the iPhone! When I connect it my iPhone vibrates to let me know that it is charging (I have it on silent), but my computer will not recognize any new devices, my iPhone will not ask to trust this computer, and my iTunes will not recognize it, no app recognizes it at all. Therefore I cannot install iOS 11 because I think its because I have Cydia, I can't uninstall jailbreak because you have to have access to Cydia (which I don't have), but I cannot jailbreak my iPhone to have access to Cydia because my computer will not recognize my iPhone. Here is what I have tried: 1. Use Apple approved connectors 2. Tried every USB slot on my computer 3. Tried factory resetting my iPhone 6s (when I factory reset all the apps were gone exempt the default apps the jailbreak apps) 4. I have updated iTunes 5. I made sure my iPhone 6s was on and unlocked while it was plugged in All of these attempts did not work and I'm desperate for answers. Please help me. EDIT 1: I have tried DFU mode, I had my phone connected to the computer, I put it in DFU mode (nothing appeared on the screen as it should) HOWEVER my iTunes is not recognizing that my iPhone is not in DFU mode, it's not recognizing it at all. I think it is because my computer itself does not recognize my iPhone. YES I DO HAVE THE LATEST ITUNES. Edit 2: I have tried to plug my iPhone 6s to my brother's computer, it is windows 10. It would not recognize my iPhone. I've come to the conclusion that it's not my computers fault but that my iPhone is the reason why any of the computers cannot recognize it. I repeat THE IPHONE is the reason why any computers will not recognize it.
