Updating to iOS 9 Manually with Firmware and iTunes

This will update a device running a prior version of iOS to iOS 9, as described here it will perform a software update, it does not restore or reset the device. Nonetheless, always backup before beginning a software update.

Place the file somewhere easy to locate, like the desktop

Launch iTunes after you have the latest version

Connect the iPhone, iPad, or iPod touch to the computer with a USB cable

Select the device in iTunes

Under the Backups section, either choose iCloud, or choose “Back up to this computer” and select ‘Encrypt iPhone backup’ , then click “Back Up Now” – don’t skip backing up! When finished backing up, continue

Now you must choose to use an IPSW file by entering an alternate update method:

For Mac: OPTION + Click on the “Update” button
For Windows: SHIFT + Click on the ‘Update’ button

Navigate in the file system to the IPSW file you downloaded and select it

Confirm that you want to update to iOS 9 by clicking on ‘Update’

Let the process complete, this can take a little while

iTunes will show a progress bar as it extracts the software from the IPSW file, updates the iPhone / iPad / iPod touch, and then reboots. DO NOT INTERFERE with the device when it is being updated, doing so may mess up the update.
