Phone unused for a year, forgot the code

Hi all,
I have a Lumia 535
This summer, I accidentally broken the screen
I bought an android smartphone so I didn't moved pictures and anything...
Now, I made it repair but I forgot the code that I inserted into the phone!!!
Is there any way to unlock and access the pictures? I only want them...
The phone is mine, I got also boxes and original cables...
I don't want to hard reset..
I never done root or hacking on this one...
Can I dump the memory or some other methods?

Thanks a lot
