Get ADB working on a locked and unrooted device?

Good afternoon,
I need to grab some files from a device with a shattered screen. Unfortunately it's locked with a pattern, the Bootloader is locked and the device isn't rooted. I can't try anything out right now because I don't have the device right now and when I have it I will only have a short amount of time, so it would be good to already know how to (probably) do it.
I never owned a device with a locked Bootloader, so I don't exactly know what you can and what you can't do. My idea was to boot into cwm or twrp via "fastboot boot", and then adb pull the files. But that doesn't work as long as the bootloader is locked, am I right? Is there any possibility to unlock the Bootloader through fastboot?
I already found a solution. Why did it take me so long to think about that? I'll simply connect a mouse via USB OTG...

Issue unlocking bootloader on US996

Hello,
I am going through the official way of unlocking the bootloader through developer.lge.com
I am trying to see my device's ID but can't get into boot loader mode
When ever I run "adb reboot bootloader" in CMD I get the message "no device/emulator found"
- OEM unlock is enabled
- USB debugging is enabeled
- I am using LG usb drivers
Did a ton of googling and not sure what else to try.
I wanna root this phone so bad!
Well I was able to get past the ID issue by using a different PC, however once I was able to input my device ID and everything into the LG site, the message I got was this:
Your device (LGUS996Z) does not support unlocking the bootloader. Please check your model. Your account will be locked if you enter the wrong information more than 8 times.
I don't even understand how it's possible if this us a US996.. gonna be pretty upset if I can't unlock the bootloader
What the heck is a LGUS996Z anyway!?
Gonna be really upset if I can't unlock the bootloader
Here's a picture of the model number sticker:

pretty sure it isn't the us cellular version

Impossible to unlock the bootloader

Hello
I sent my device for warranty because I have ghost touches. I received my phone and they brought it back without any change, I'm still facing ghost touches. BTW thats not the problem.
Previously I unlocked the bootloader and rooted my device, before to send the device for warranty I locked the bootloader again and sent it like it was new.
Now I'm trying to unlock the bootloader but it is impossible to do. When I try to get the fastboot oem unlock data, I put the code on the motorola website and the answer is "Your devices does not qualify for bootloader unlocking".
I tried too to put the old code that Motorola sent me to my email, I put the commands on adb window but also I get an error message "Code validation failure with status 7".
If someone have faced this issue would be great to know how to solve it.
Thanks.

Bootloader not unlocking

Hello there, probably this is one of the stupid questions that you will read so I am sorry.
I got this phone in state of BLOD, checked and found out that I need the device unlocked so I decided freezing will do that job after reading the infamous guide on this page. Took it out and woila, it turns on now. I happily go to settings, enable developer options, and enable OEM unlock and USB debugging, happily restarted my phone and it's still locked. after dancing around for some time trying to find a way to unlock it, I decided to flash official os (android 8) through recovery mode ADB. Now I can't even boot by putting it into a freezer and when I try to flash an other version like android 6, it says that it's meant for "Angler" and my device is "", yeah "" it's empty.
Do I put this device in a wall I am building?

Not an expert but what you had to do was oem unlock and then usb debugging, after that connect the device and give ADB the permission so it installs adb interface driver. After that, reboot to bootloader open adb and try to unlock. It wouldn't be possible so, you manually install the google driver so it installs the bootloader interface, after that do the fastboot unlocking

yes i did, still i get stuck half way thru on odin when i was trying to install twrp
So in your bootloader after pressing up(short click not long), on the upper screen does it say Oem lock = true or false?
If it says oem lock = off it sounds like you have to flash vbmeta in AP so you can flash unofficial binaries. Sorry if I can't follow your problem correctly, just trying to figure out if you just failed at some point or if something really is going wrong... This phone should unlock really easily.
Also may I ask which guide you are following?
Edit: Saw your post on the TWRP thread. So it seems your bootloader is unlocked! As long as you can boot to it you are fine, don't worry!
Get your firmware from frija, https://forum.xda-developers.com/t/tool-frija-samsung-firmware-downloader-checker.3910594/
Make sure you get the right Firmware (Look at your phones box if you still have it, CSC should be at the end of the Model number, also my Box says its a M30FZ even tho it's a M30FN).
After you're back to running firmware and still wanting to install magisk, follow santooshs TWRP thread's install guide.
