HP Prime Firmware Update Problem

[Maestro]

If I could duplicate the functionality of the device without the touchscreen, I would probably be OK. I get tired of fingerprints on the screen anyway, so I could do with just physical buttons. However, I do not believe I can program or use many of the Apps without access to the soft buttons (that I am aware of), so I guess I have to exchange this broken unit at Best Buy. If anyone knows how to duplicate the soft buttons with physical key presses, please let me know before I take it in (in about 5 hours).
