If you unfortunately forgot your password and failed to unlock your iPhone for a couple of times, your iPhone might be disabled. You will be asked to wait for a while to try again. But what if you cannot remember the password even hours later or you just cannot be patient to wait.
Here I would like to share three different solutions for the unlocking.
Solution 1: Restore your iPhone through iTunes
Step 1: Launch your iTunes on your computer, if there is update available, please update at first.
Step 2: Connect your iPhone to your computer, click the icon for your iPhone after it is detected by your iTunes.
Step 3: Click Back up Now on the interface of iTunes.
Step 4: Click Restore iPhone after the syncing finishes. And your iPhone will be restored to factory settings.
Step 5: You can choose to set up your iPhone as new or restore from a previous backup file.
Solution 2: Restore your iPhone from iCloud
Step 1: Sign in your iCloud with your Apple ID on your computer.
Step 2: Click “Find My iPhone”.
Step 3: iCloud will therefore locate your iPhone. Choose “Erase iPhone” and thus the disabled situation will be unlocked.
Note: You can only do so when you switched on “Find My iPhone” and your iPhone is wifi connected.
Step 4: Follow onscreen instructions to erase all content and settings and then setup your iPhone as new or use a previous iCloud backup file.
Solution 3: Restore through Recovery Mode
What if you don't have old back and didn't synced your device previously. We need to turn to Recovery Mode for help.
Step 1: Turn the device off by holding the power button and sliding off.
Step 2: Connect to iTunes.
Step 3: Hold both home button and power button until the screen lights up.
Step 4: Once the screen lights up, release the power button and keep the home button until you see “Connect to iTunes” appears.
Step 5: Release the home button after you see iTunes icon.
Step 6: Now you will see message says that ( iTunes Has Detected An iPhone In Recovery Mode ) Once you click OK to agree that message and the next step hit restore button again , at this time the process of getting last backup and running . Unfortunately with this message the data on the device will be lost and there is no way to preserve.
