How to recover files on my locked LG G3 phone?

Hi guys, I hope I can get some help here. This is my situation... My kid locked my LG G3 by entering many times a wrong unlock pattern. Now I can see just a lock screen and I can't use the two available options to unlock it which are:

1. entering a PIN - I didn't set one
2. unlocking with my Google account - I don't have Internet and I cant use this. I can neither turn my data connection on nor enable my wi-fi because I can only see the lock screen.

This is how my phone is somehow soft bricked, because I can't do anything with it. I can only reset it by removing all files and settings from recovery mode but I want to save my files. So, the question is how can I recover my files in this situation? Here are all of the details:

- my phone is not rooted
- I can enter in download and recovery mode
- I DO NOT have usb debugging on, I can't use ADB
- I remember my unlock pattern and my Google account credentials, but I can't use them.
- I don't have Android Device Manager enabled, I can't unlock from: google.com/android/devicemanager

If you need some other details, I will provide em. Thanks in advance.

The following method only applies to devices that have Android Device Manager enabled.

On a computer or other mobile phone, visit:*google.com/android/devicemanagerSign in using your Google login details that you also used on your locked phone.In the ADM interface, select the device you need to unlock (if it isn’t already selected).Select ‘Lock’In the appearing window, enter a temporary password. You don’t have to enter a recovery message. Now click ‘Lock’ again.If it was successful, you should see a confirmation below the box with the buttons Ring, Lock and Erase.On your phone you should now see a password field in which you should enter the temporary password. This should unlock your phone.Now, before you go on with your life, go to your phone’s lock screen settings and disable the temporary password.

A good idea, but I don;t have Android Device Manager enabled, any other ideas? I need to turn usb debugging on somehow or do something via the download mode. This would help.

Are you able to reset the phone manually? Other than this... I don't think there is another option.

Yes, I can reset the phone, but this is what I really don't want to do. I will lose all of my photos from the last several years which is really bad solution of the situation. Come on, there must be another option. I will consider suggestions like breaking the phone apart and pulling out the memory chip, I don;t want to lose my photos and files.

Hello, did you solve that situation without losing your files? I have exactly the same problem and I'm out of ideas. I'd be really grateful if you could help me.
