In addition to @dadibrokeit 's thoughts:
It doesn't sound 'kosher' to me, sounds like a botched repair but I don't know that... Many phones these days intentionally block functions of 3rd party parts (Apple, Samsung) but that doesn't seem to be true of Honor (yet) So:
Besides seeking a repair that works instead of rolling over...
You can try getting into your phone in several ways:
Method 1: Unlock using Android Device Manager (ADM), also called Google Find My Device, can unlock remotely... IF already enabled! To use it:
1. Open a web browser (on another device) and go to the Google Find My Device page and sign in with the same Google account as your phone.
2. After you log in, select the locked device from those linked to the Google account.
3. Click the “Lock” option and set a temporary password. Next, click "Lock" again to confirm.
4. Go to your phone, lock screen settings and disable the temporary password.
I'm not sure this will help if the screen still won't let you enter the pin... if so, I'd try NOT locking it checking to see it you have access and try chaning or turning off the secure login. (I'm guessing on this.)
Method 2: If you are running Android 4.4 or lower, (doubtful) you can unlock your phone without a PIN or pattern by using your Google account:
1. Enter the wrong PIN or pattern five times in a row. Your phone will block another attempt for 30 seconds.
2. After the wait, you’ll see an option "Forgot Pattern" at the bottom of the screen.
3. You’ll be prompted to enter your backup PIN OR log in with your Google account. Sign in with the Google account linked to this device.
4. Unlock your phone: Once signed in, your phone will unlock, and you can create a new screen lock method if you wish.
Method 3: Factory Reset
If you HAVEN'T enabled ADM a factory reset is an option.
THIS WILL DELETE ALL YOUR DATA, INCLUDING THE PASSWORD!
To do this:
1. Turn off the phone and disconnect any cables.
2. Press and hold the volume up and power buttons simultaneously—until the recovery mode screen appears.
3. Scroll the recovery menu using the volume buttons and select option to factory reset.
4. Confirm: The phone will reset to the out of the box state...
(ERASING EVERYTHING but what it came with!)
5. Reboot... the phone will reboot, allowing you to configure it as a new device.
You possibly can recover your important files via the HONOR Cloud service after the factory reset. it syncs your app data, notes, passwords, and other essential files across devices, so you may not lose data permanently.
Unlock Phone without PIN/Pattern via Google Account
Someone else may have a better idea for you, but that's the limit of my knowledge on this one.
Good Luck.
