Apple released iOS 9.1 for iPhone, iPad and iPod touch, which includes number of bug fixes and improvements. Apple has also patched two Pangu jailbreak vulnerabilities in iOS 9.1, so you won’t be able to use it to jailbreak iOS 9.1.
If you want to upgrade to iOS 9, and jailbreak your device then you have a small window of opportunity as Apple is still signing the iOS 9.0.2 firmware file. So if you’re on iOS 8.x.x then you can update your device to iOS 9.0.2, and still jailbreak iPhone, iPad or iPod touch using Pangu Jailbreak.
Please note that Apple can stop signing iOS 9.0.2 firmware files any moment. You won’t be able to upgrade to 9.0.2 once Apple stops signing the firmware file. So install iOS 9.0.2 as soon as possible.
- You will be able to update only to iOS 9.0.2.
- You will be able to update as long as Apple continues to sign iOS 9.0.2 firmware file.
- Similarly, if you want to downgrade from iOS 9.1 to iOS 9.0.2, then you can check our article for step-by-step instructions:
- It is important to take a backup of your iOS device to iCloud or using iTunes so you can restore from the backup if something goes wrong.

How to install iOS 9.0.2 software update
If Apple is still signing iOS 9.0.2, please follow these simple instructions to update to iOS 9.0.2:
- Turn off Find my iPhone via the Settings app (Settings > iCloud > Find my iPhone).
- Download the iOS 9.0.2 firmware file for your device. The iOS 9.0.2 firmware file for iPhone 6 Plus, model number A1524 (which can be found at the back of your device) is iPhone7,1_9.0.2_13A452_Restore.ipsw. Accordingly, download the appropriate firmware file from our iOS firmware file download page for your iPhone, iPad or iPod touch.
Note: If you’re downloading the firmware file using Safari then ensure that auto unzip feature is disabled or use Chrome or Firefox. Alternatively, renaming the .zip file as .ipsw file should also work.
- Connect the iOS device to your computer.
- Launch iTunes and select the iOS device from the top left corner.
- Hold the Alt/Option key on the Mac or Shift Key in Windows on your keyboard and click on the Check for Update option, instead of restoring. Important: Please note that holding the Alt/Option key on the Mac or Shift Key in Windows is very important. If you don’t press them then iTunes will update your device to iOS 9.1, so please be careful.
- Select the iOS 9.0.2 ipsw file you had downloaded earlier.
- iTunes will inform that it will update your iOS device to iOS 9.0.2 and will verify the update with Apple.
- Click Update.
- iTunes should now install iOS 9.0.2 on your device.
- After downgrading, the iOS device will restart. You should then see “Slide to upgrade”. Enter the passcode, and then wait for the downgrade process to complete. You may be prompted to activate your device.
That’s it. Your device should now be successfully upgraded to iOS 9.0.2.
If you get the error message “This device isn’t eligible for the requested build” then it is probably because Apple has stopped signing the iOS 9.0.2 firmware file or you’ve downloaded the wrong firmware file for your device.
