A "Hard Reset" is meant to completely wipe the device and then download and reinstall the original OS and apps. So it isn't meant to allow for getting data back. That said, you can try the following and see if it will help.
There are a few apps/programs out there that "may" be able to help you recover the data.
A few of the programs you could try would be... DiskDigger, MobiSaver, Android-Recovery and Tenorshare. They are all data recovery apps/programs. There are many others out there, so check around and see which you would rather try. There is also one called RECUVA, that I have heard is free, which you could try.
One important note though, most of these programs are not free. They may say they are "free" or have "Free Trials"...
