3 weeks ago another NL29 on FW 6.2.1 malfunctioned.
Boot up video: https://youtu.be/VTIgSCBrQ2c
After about "5 minutes" it may flash green 3 times every 20 seconds or white and then usually the whole control square goes off while the rest remain on.
Doesn't request IP or connect to WiFi.
Touch bottons unresponsive.
Won't soft or hard reset.
Does anyone know how to recover it?
