Missing pictures and videos

[Spiritualengr]

I just went import/backup all the photos and videos on my phone to my computer before I ran the new update. I noticed that I'm missing a lot of media from the last two to three weeks, including everything I recorded and shot over the holidays. There where there a couple of days ago because a head sent a few to my wife. They apparently didn't get backed up onto the OneDrive. I looked and the last pictures on there where from Dec. 18. I have been on WiFi constantly since the 28 & was rarely off of it while traveling.

I have tried running recovery software but I can't find one that will recognize this phone.

Any help or idea on how to get these files back?
