Apple made iOS 9 (and subsequently iOS 9.1) beta public for anyone to test out. You were no longer restricted to needing a developer account with Apple to give the upcoming iOS version a try and lots of people got to preview the operating system before hand. That said, it is iOS day and iOS 9 has been released to the stable channel. As you read this, countless users are downloading and upgrading to it (while others are going to wait until the jailbreak is out). If you took the iOS 9 or iOS 9.1 beta for a spin, you might be wondering how you can get the stable and final release of iOS 9 on your device. Here’s the walkthrough.
Step 1: Open iTunes and make sure you have the latest version running. While you’re at it, make sure the charging cable isn’t damaged since we’re trying to avoid errors caused by faulty cables or outdated iTunes.
Step 2: On your iPhone, go to Settings>iCloud and disable Find my iPhone.
Step 3. Open iTunes on your desktop and connect your device.
Step 4: Put your device into Restore mode. To do so, hold down the Power and Home button until you see the Apple logo. Once you see the logo, release the Power button but keep pressing the Home button until you see on the screen the familiar connect to iTunes screen.
Step 5: When iTunes detects the phone in recovery mode, it will give you the option to restore the phone or update it. Click the ‘Update’ button.
Step 7: While your wait for iOS 9 to download via iTunes, make yourself a thin crust pizza. (Your phone might exit recovery mode and if it does, simply put it back in recovery mode once iOS 9 has downloaded. Connect it to your computer and follow steps 5 and onward skipping Step 7).
Step 8: Once iOS 9 has downloaded, iTunes will update the phone and install the latest stable version of the operating system
Step 9: The iPhone will upgrade as it normally does. Once it’s done, it will ask you to unlock the device with the slider text reading ‘Slide to upgrade’. That’s all it takes.
