If you do not work very well the physical volume buttons and so to access the options, you have few options:
Or you're patient and you're playing with the buttons to see if one of the times reacts ...
Or you can install some different recovery, and since many of them can use them or with the physical buttons or touch buttons.
I can say little more.
I use a philz TOUCH recovery and management with the touch screen itself without touching any hardware button.
