Hi. I have and issue while upgrading my Balance 310 from 5.x firmware to 6.3.3.
During flashing process I have power failed down. After that Balance 310 can not start, it has Power (green) and Status (red) are turned on all the time. I have tryed to reset it, but all in vain.
As far as I know, it has two firmware slots and second (backup) slot is made specially for such troubles, that I have.
Could someone kindly explain, how to make second slot active and boot the router?
