If you have similar question, please read this thread.
The device is blinking and won’t allow me to use the device. When on charge it charges but when I try to use to lights just keep blinking


Answer:
The Yocan UNI flashes 5 times means the battery wont detect the vape cartridges.
Please try to loose the 510 thread adapter, or use a q-tip to clean the contact points.
