How do I either remove the PIN or retrieve the files from a locked S3 Neo?

I'll keep it short, my girlfriend's phone is locked, a PIN code, she forgot the code and now can't unlock it. She used the ADM to lock it and for some reason when you enter wrong PINs no option to login with your google account comes up. She doesn't to hard reset it because she can't risk losing the files. We tried using the Dr.Fone software to either lift the lock or extract the files but the program recognises her S3 Neo as a Sony phone for some reason.
Any ideas?
