Bricked in rommon mode, flash is missing

Hello all,

I have a C3850 that was powered on for the first time today, and seems to be bricked, only booting into rommon mode. The flash directory is missing, and I can't do an emergency recovery because the sda9 directory is missing as well. I tried to boot from a usb flash drive but that is failing as well. This switch has been sitting for a couple of years and had never been utilized before. Below I have listed in the comments the output for my boot attempts and directory verification/troubleshooting. Any input or assistance is greatly appreciated.
