iPhone6 doesn t know the passcode how to unlock the passcode

Before you start the operation, if the "Find My iPhone" in iCloud on your iPhone6 phone is turned on, be sure to know the Apple ID and its password, otherwise the phone will not be activated after the system is restored. If you don't know the password, it's best to stop doing the following.

If you belong to the family who can currently unlock the mobile phone with your fingerprint, but you have forgotten the "boot password" that you originally set, we can back up the personal data of the iphone6 on the computer first. If you don't have one, you can skip the step of backing up your data.

Next, connect your phone to a computer with iTunes software installed, or install it if you haven't already.

When iTunes recognizes your iPhone 6, tap the phone icon in the window, as shown in the image below.

Then, in the management summary screen of your iPhone, click the "Back up now" button and choose to back up the data on your phone according to your personal needs.

When you're done backing up your data, turn off your iPoNe6 phone. Press and hold the power button, and then slide it to power off.

Next, please press the operation below to get your iPhone6 into recovery mode:

First, please press the power button to turn on, when the screen will appear Apple logo, do not release the power button;

2. Then press and hold the home button on the home screen until the screen goes black;

3. When you see the screen black, please release the power button and continue to press and hold the home button on the home screen until iTunes on the computer detects an iPhone in recovery mode.

If you don't succeed in getting your iPhone into recovery mode, try a few more times, starting with step five.

Then click the "Restore iPhone" button in the iTunes window, as shown in the image below.

Note: Many friends will notice the "Serial number not applicable" prompt in the iTunes window at this step, since it is in recovery mode, it is normal to show that it is not available here, no need to worry.

Then iTunes will connect to Apple's update server, detect the latest iOS phone system, and prompt us if we want to delete all data on the phone and restore it, click the "Restore and update" button to continue.

iTunes will then automatically restore the required iOS system from Apple's update servers, and when it does, it will automatically restore it to your iPhone.

Finally, when the recovery is successful, reactivating the iphone6 phone is equivalent to restoring the factory settings of the system, and you can set the boot password for the phone again.

After connecting your phone to your computer, open iTunes on your computer.

Then go to iTunes and select your phone button in Devices.

If you haven't used iTunes before, you'll need to sign in to your iCloud account.

Next, here you can choose to restore my iPhone.

Next, choose whether to back up first.

This method is to do a factory reset and then log in to your phone again, so that you don't have to enter the screen lock password to enter the phone.
