This firmware update is designed for the WYE 200w.

Please note this update is not designed for the WYE 85W and will make your device unusable if installed.

We have recently encountered an error with a small number of WYE Mods where the device will occasionally shut down and not power back on for some time.

To apply the firmware update please follow these steps in order [Video Instructions also available below]:

  1. Remove Batteries from the WYE mod
  2. Press and hold the up and down buttons together whilst plugging in the usb from your computer.
  3. Drag and drop the firmware update file into the folder of the WYE.
  4. The Teslacigs logo will then appear on the screen of the mod and then the update is complete
  5. Please unplug device from your computer and use the device as normal
