Print halted

My print is halted, probably due to a bad connection to the hotend thermistor. The smoothie LEDs are flashing, but I cannot connect via the serial or ethernet connections.
Is it possible to restart the print?

it’s probably too late now anyways, but no there is no way to cleanly restart the print, unless you have some means to find out at exactly what line of gcode the file stopped.
