- You can return to using firmware 10.1.1 only as long as Apple signs iOS 10.1.1 firmware files.
- It is important to backup your iOS device using either iCloud services or iTunes, so that you can recover from a backup if something goes wrong.
- Please note that the process includesdeleting all data from your device and then restoring it from a backup, so this may take some time depending on how much data needs to be restored and the speed of your Internet connection (if you are restoring from a backup from iCloud).

- Click on the OK button.
- While holding down the Alt / Option key on a Mac or the Shift key in Windows on the keyboard, click the Restore iPhone ... (iPad / iPod Touch ...) button.
