Normally the reset to bootloader is a quick double tap not a single tap. Why a HEX file ---

Which OS? Uploading to a Lenoardo is a two step process. First step is the reset (IDE does this by opening and closing the Serial port with a baudrate of 1200 baud) followed by the upload. In the IDE, file -\> preferences and enable verbose output during upload. Next observe in the output window what happens when you upload e.g. blink. A single tap of the reset button should work, it does on my Leonardo. If the reset button does not result in a reset, the reset button is broken 😉 ---

Afterthought: The Leonardo identifies itself as Arduino Leonardo (COMX) in Windows; if you're using Windows and it does not identify itself as that, it's not a Leonardo and the com port will probably not change because of that. ---
