4. Method 4: How do Apple iOS9 Beta, iOS9 GM, and iOS9.1 Beta1 users upgrade to the official version of iOS9?

According to previous practice, iOS9 GM (version number 13A340) should be exactly the same as the official version to be pushed in the early morning of the 17th, so these users will not be able to receive update prompts. After iOS9.0.1 is released later, they can normally start from GM upgrade. The iOS9.1 Beta1 version is higher than the version that will be pushed soon, so naturally you will not be able to receive this update.

If you want to re-flash the iOS9 official version firmware, you can only download the corresponding firmware according to the method provided in "Method 2", and then use iTunes to flash it. For iOS9.1 Beta1 public beta users, they need to first delete the previously installed description file, restart, and then flash the phone normally.

Hope this helps,
