Iphone 6 not restoring on itunes. Why?

So am restoring my iphone 6 because it got stuck on the apple logo. This happened because i tried to restarting the phone by holding the power button and home button while it was frozen on a app. It never restarted back to the home screen and instead stayed on the apple logo. Now the bigger issue is while it is downloading the software update so it can restore, the iphone goes from the recovery screen to the apple logo. I don't think this is normal because it isn't showing the loading line at the bottom of the apple logo. When the software update is finished downloading on itunes it says error can't download update because of my Wi-Fi.

  • Will restoring my iPhone on my iTunes unlock my forgotten passcode? I put a new passcode on then stupidly forgot it and nkw I can't get in because i'm getting it wrong. I've read to restore it on the computer which I'm doing now but i'm scared it won't work. What do I do if it doesn't? And will it work?
  • Why is my iphone 4 (not an IOS) not connecting to my itunes 10.6? I've downloaded the latest version of itunes 5 times and every single time it says "the iphone can't be used because it requires iTunes version 10.5 or later". What to do? What to do?
  • What Does Restoring An iPhone Using iTunes Do Exactly? I have a jailbroken iphone 4. Yesterday, I deleted a file from the system of the iPhone using iExplorer on Windows (I deleted the file so that I fix an issue), The issue I was having was gone after deleting the file from system. The question: If I restore my iPhone using iTunes to factory settings, I know the jailbreak would go, but will the DELETED file reappear again? Thanks for reading, now you can answer (if you know it) :D
  • Restoring iphone information not using icloud? I recently broke my iphone 4s (kept up to date in software). I don't believe I ticked the icloud option on. However, my phone did make backups to itunes whenever I charge it. If I get a new phone, what information will carry over to my new phone? (Trying to keep as much as I can) Someone also told me that if I could log into the app store that my information and contacts have already been stored to the cloud, wondering if that's true?
