I have a phone that I cannot unlock with device password.
I already tried with all the codes that I know, is there anything I can still do besides a hard reset?
I really need all the information from the phone.

You have to delete a file called system/etc/locksettings.db
is it possible to do without root
Not really. TWRP etc.
What is TWRP?
Don’t know if this will be helpful but check this out:
