Kodo Device lights indicate it is charging but once I take it off the charger it blinks 5 times when I try to use it.
The Kodo vape mod flashing 5 times when you hit the fire button, means that it detect short-circuit.
Please check the 510 threaded oil cartridge, try to use q-tip to clean the contact points.
Or install brand new cartridge, and hold the power button of Yocan Kodo.
If above vape tricks still fix this issue, please contact Yocan support team.
