ADM not allowing me to reset the passcode on my HTC Bolt


AC Question

So around a month ago, I got this HTC Bolt. My one friend knows my password, and i don't want him knowing my password, so today I decided to enter a pattern lock. Almost immediately, I forgot this pattern, and to make a long story short, I'm locked out of my phone. I can't use the fingerprint scanner, and it won't let me use any alternative methods. I tried the Android Device Manager, I told it to reset the password to a PIN, but it told me "Since Google has verified that a screen lock is already set, the password you entered won't be needed." Yes, I'm aware there's a screen lock already. I need to reset it, please and thanks. My Bolt is running Android 7.0 Nougat, and some people have been saying that ADM doesn't work with newer versions of Android. However, I'd love to get back into my phone WITHOUT deleting everything. Is there any way to either get ADM working or to get into my phone without a screen lock?
