Method 1: Fix Disabled/Locked iPhone or iPad using iTunes without Losing Data
If you have synced your iPhone or iPad with iTunes before, it is easy to unlock your device by restoring. To avoid data loss, download and install Yolisoft iPhone Data Recovery on your computer first. It is a professional tool to help you retrieve deleted or lost data from your iDevice directly or from iTunes or iCloud backup.
Method 2: Unlock Disabled/Locked iPhone or iPad by Using iCloud
Provided that you have set up "Find My iPhone" on your iPhone or iPad, you can use iCloud to get back your device.
Go to https://www.icloud.com/#find on your computer or other device.
Sign in with your iCloud Apple ID.
Click "Find My iPhone" and "All Devices" at the top of your browser window.
Choose the iPhone or iPad you want to erase, and click "Erase iPhone/iPad" on the top right.
After the process completed, there is no passcode on your lock screen. Now you can choose to either set up as a new iPhone/ iPad or restore it from the iCloud backup.
Method 3: Unlock Disabled/Locked iPhone, iPad or iPod Touch in Recovery Mode
If you have never backed up your iPhone or iPad and set up Find My iPhone in iCloud or synced your device with iTunes, recovery mode is your last resort to restore your device.
Open iTunes and connect your iOS device with your computer or Mac via an USB cable.
Turn off the iPhone or iPad by holding the Power button to swipe the "slide to power off" to the right.
On an iPhone 6s and earlier, or iPad: press and hold the Power and Home buttons at the same time. On an iPhone 7 or iPhone 7 Plus: press and hold the Power and Volume Down buttons at the same time. Don't let go of the two buttons until you see the recovery mode screen.
A message will pop up which means your device have been in recovery mode. You will be asked to choose Update or Restore. Click "Restore". iTunes will download software for your iPhone or iPad. It might take some time to restore your device.
After the restoring process finished, you will see a white screen with "Hello" in different languages. Then you can reset your device as a new one.
