Did you just update your Apple device to iOS 9.1 and you are considering downgrading it to 9.0.2? Well you’ve come to the right place, because today we’re going to teach you how to downgrade your iPhone, iPad or iPod Touch from iOS 9.1 to 9.0.2.
One of the main reasons why people want to downgrade their iDevices to iOS 9.0.2 is that 9.1 is currently not jailbreakable, the 9.0.2 update can be jailbroken using the tool offered by the Pangu hacker team.
Keep in mind that downgrading to iOS 9.1 is now possible because Apple is still signing the 9.0.2 firmware, but once the American multinational technology company headquartered in Cupertino, California will stop signing that iOS version, you will no longer be able to downgrade your iDevice back to 9.0.2.
First of all, you will need the iOS 9.0.2 IPSW file that’s exactly created for your device, keep in mind that if you download an IPSW file that’s not made for your iDevice, it will not work, at the same time, you will need the latest iTunes version 12.3.1 or older for Windows or Mac.
HINT: Keep in mind that full iTunes backups made on iOS 9.1 will not be restorable on 9.0.2 because backups that are made on higher versions of iOS are not compatible with older versions of iOS, so, instead of doing a full iTunes backup just sync the data individually to iTunes and save them manually on your computer.
Downgrading iDevice From 9.1 to 9.0.2
First of all, turn off the Touch ID & Passcode feature by going to your device’s Settings->Touch ID & Passcode, also, you will need to disable the “Find My iPhone” feature by going to Settings->iCloud->Find My iPhone.
Now connect the device to your Windows PC or Mac and launch the iTunes application, after that, you will need to tap on the Summary tab that’s located in the left panel, right under Settings, now, you will notice that iTunes will display details of your connected iDevice, including the current iOS version that the device is currently running on.
You will need to hold down the Shift key (if you are on Windows) or the Option/Alt key (if you are using a Mac), click on “Restore iPhone” and a new window will pop-up requesting you to browse the IPSW file (the 9.0.2 IPSW file that you’ve downloaded), once you do this, the iTunes will downgrade your iDevice back to 9.0.2 update, this will take about 10-15 minutes and once it’s done, your iDevice will automatically restart.
