Stuck updating Amlogic M8 firmware.


I'm trying to flash a rom I've picked up for this particular series boxes. The problem is that once I have booted into the android system recovery <3e> it requires me to move by using the volume buttons and enter button to select. There are no volume buttons to use for selecting, I've tried my wired usb mouse and keyboard and neither got me anywhere. Also tried the wireless keyboard/remote that came with the unit to no avail. Does anyone have any suggestions for me? Thanks!
