How to Downgrade iOS 9.1 to iOS 9.0.2 and Keep Your Data

downgrade iOS 9.1Now is the best time to downgrade iOS 9.1 to iOS 9.0.2, at least for jailbreakers. If you want to install cydia on your device and benefit from all sorts of themes, tweaks and apps that are not available in the iTunes App Store, you should get your device onto an earlier version of iOS. Being that iOS 9.0.2 is the latest jailbreakable version of Apple’s mobile operating system, it is the ideal version to downgrade to. Here’s a tutorial on how to downgrade iOS 9.1 and make your iPhone jailbreakable for the Pangu jailbreak.

Apple is still signing iOS 9.0.2, at least for now. Signing means, in this context, that the respective firmware is still usable for a manual restore process. We can download the appropriate IPSW file for your device and install it using iTunes on a Mac or PC. The download is necessary, as iTunes only offers the most recent version by itself, which we can’t use.

Prerequisites: A device running iOS 9.1, the right timing and of course a full backup of your device.

How to properly back up your iPhone

We wrote a guide on how to back up your iPhone and suggest you create a full iTunes backup of your device (including purchases), to make sure that no data is lost. And additionally, to speed up the recovery process, if needed. Our method aims to reduce data loss as far as possible, but as always with restoration, there is no guarantee whatsoever.

How to downgrade iOS 9.1 to iOS 9.0.2

  • First of all, download the appropriate firmware file (IPSW) for your device and iOS version 9.0.2 on this IPSW downloads website. You can also use the site to check whether this firmware version is still signed by Apple. Use a PC or a Mac for this task and take note of where you save the file (don’t run it, please save it!).
  • Connect your iPhone or iPad to the computer, using a regular Apple USB sync cable.
  • Shut it down by pressing and holding the Power Button and “slide to power off” as soon as the slider is displayed. Wait for approximately one or two minutes for the shutdown to complete.
  • Now press and hold the Home Button until iTunes says “There is a problem with the iPhone that requires it to be updated or restored”. It should boot up and display only the iTunes icon and a lightning cable illustration.
  • In the iTunes dialog window, click “Cancel”.
  • If you are on a Mac, hold the Option/Alt-Key.
  • If you are running Windows, hold the Shift-Key.
  • Now click on “Update” in iTunes, while still holding the respective keyboard key. This will allow you to select the file we previously downloaded in the first step.
  • Patiently wait for the update procedure to go through, it will actually downgrade your iOS to the selected firmware version. Do not disconnect the device, nor try to shut it or your computer off.
  • That’s it! Follow the on-screen instructions on your iPhone to finalize the setup process and all of your files and personal data should still be on the device.


Hint: If the above does not work for you, for some reason, then try clicking “Restore iPhone” instead of “Update” and select the firmware file. Note that backups created on iOS 9.1 are not available for import in iOS 9.0.2 and you will lose a lot of your settings.

How to verify your current iOS version

To check if you are on the right version of iOS for jailbreaking, simply run the Pangu jailbreak tool and it will notify you of any issues.

Settings > General > About > Version

Another way is to open up the “Settings” app on your device and tap “General”, then “Info” and check the field labeled “Version”. It should now say 9.0.2, as long as everything went by plan.
