Hi Reagan!
Can you share a video with us? Then we can see what is happening.
Please make sure that you use a known working hard drive. And that you use the "PS4 Console Reinstallation file" instead the update only. This one can be found here: https://www.playstation.com/en-us/support/hardware/ps4/system-software/
Also make sure that the USB is formatted in FAT32 and that the "PS4" and "UPDATE" folders are created, like this:
Root > PS4 > UPDATE > (Place update in this folder).
Please let us know if this worked.
