If your cuboid shows the atomiser short screen here’s a simple quick fix.
1. Release the battery door.
2. Hold down the fire button and don’t let go.
3. Close the battery door while still holding down the fire button.
4. Wait a couple of seconds while still holding the fire button.
5. You should see the coil screen begin to read the ohm.
6. Release the fire button.
7. Continue to vape.
8. Go buy a new mod because it only gets worse and eventually breaks altogether. Thanks for watching and give me a thumbs up.
