How to download and install iOS 9 final version:
Before installing the final version of iOS 9, it’s highly recommended to make a complete backup of your device to either iCloud or using iTunes to your computer. We have separate detailed guide on how to make the backup and prepare your device for iOS 9 that you can check out here. Once you are done with making backup using the instructions provided at that link, follow the instructions below to install iOS 9 on your device.
Clean Install:
This is the recommended way of installing any major version of iOS. Here’s how to go about about this on your device.
Step 1: Download and install latest version of iTunes from here.
Step 2: Grab the iOS 9 download link tailored for your iOS device from here: iOS 9 Download Links For iPhone, iPad, iPod touch [IPSW Links].
Step 3: Turn off Find My iPhone on your device by navigating to Settings > iCloud > Find My iPhone toggle it to off.

Step 4: Now connect your device to the computer and launch iTunes.
Step 5: From the left sidebar panel, select your iOS device from Summary tab under Settings.

Step 6: Now if you are on a Mac, hold the Alt key or if you are on Windows PC, hold the Shift key, and then click on the Restore iPhone… button as shown in the screenshot below.

Step 7: iTunes will now prompt you to select the .IPSW file you downloaded in the Step 2 above. Select it.

That’s it. Now sit back and relax as iTunes installs final version of iOS 9 on your iPhone, iPad or iPod touch. Be patient as this could take some time. Once it is installed, your device will boot directly into Hello screen of iOS 9.
OTA Update Install:
The easier way to install the iOS 9 update is to get it via the built-in OTA update mechanism in iOS. While it is easy, it is not recommended for major iOS releases such as version 9.0 as they tend to cause performance related issues. But if that sort of thing doesn’t bother you, you can give this method a go.

Make sure you backup everything as explained earlier just in case anything goes wrong. Also make sure your iPhone, iPad or iPod touch has at least 1.3GB of free space and is charged well over 50%. Once you have all of that sorted, simply head to Settings > General > Software Update and update from there.
