Hi,

After I (manual) updated my M9 deco V2 to version 1.5.3, one of the units stopped working.

Here's what I tried so far:

1. Reset the unit with the reset button (does it make any difference if you press it short or long?). This resulted in a blue pulsing LED which, according to the manual, means Deco is ready for setup.
2. Try to add a new deco using the app --> Deco cannot be found.
3. Removed the unreachable Deco from the network and repeated step 2. No success.
4. Placed the deco next to a connected deco and also connected it using an ethernet cable. Again, nothing.

Is there someone who can help me out? Any help will be appriciated 

Regards.
