Happened to me. Once the recovery menu displayed, I couldn't figure out a key combination to get out of the menu or navigate within the menu. I googled Android recovery menu and found a list of key commands including volume up/down and others but there was no response from the keyboard or mouse connected to the Rock64. Unfortunately, no one had any advice so I had to reload the eMMC and start over.
