How to recover data from a screen-bricked phone? Situation

I've got a Samsung Galaxy Fame with a broken touch screen. The owner had it protected with a pattern, and as I am unable to make this pattern with a broken screen, I cannot mount the storage in order to backup/recover data.

Some information:


Power, volume and home button are still working
I can get into recovery and download mode
The phone is stock (No custom/unlocked bootloder and no CWM)
USB-debugging is (unfortunately) disabled


What I've tried:


Connecting a mouse using OTG
Connecting to the phone using ADB
This did not work because I could not mount the sd card because I had no sudo permissions. 
Using a magnet on the screen


I would like to refer to the following question that concerns the same problem but did not give me a solution:
Android ADB Shell Recovery Mounting
This should help you: http://forum.xda-developers.com/showthread.php?t=2786395. Its a program that can mirror your phone to computer. There is also information to enable USB Debugging if you had that disabled.  

Hope my answer helps!
