Hello Kasey,
Make sure that the connectors were clean and well connected.
Maybe that during the reassembly you have damaged the flex cables.
To recover files you can try adbcontrol.
Install the proper usb android driver on pc and the ADB. Then you will be able to connect to your android devices from pc through a java Window, simulating screen and touch.

I hope you will save your files, but for the next time use Google foto with online backup or other similar services.
