Yocan UNI flashing 4 times troubleshooting

I have a uni Box vape with herb cartridge that stopped working and now only blinks 4 times when trying to use it, I have red the sugestions and have cleaned it up but it did not work. Also tried tightening and loosening. It blinks with or without the cartridge so how can I make it work again? I am no longer in the USA so replacing it wouldn't be a solution, waiting for the Support.

Answer:
The Yocan UNI device flashing 4 times, means it can't detect the atomizer.
Yes, most of time clean the contact points or loosed the adapter can solve this flashing error.

Here are other ways to fix this problem.
1. Install a brand new cartridge to have a try.
2. Contact the head shop you bought it from or get in touch Yocan support at service@yocantech.com
