Got a Chateau LTE12 today and it seems to have died within an hour of first trying it. It worked fine, got 4g signal etc and then could no longer see the wifi. Noticed all the LEDs seemed to be cycling so assumed it was stuck in a boot loop. Tried the settings reset button according to the manual, no sucess. Then tried to get it into etherboot mode for netinstall. It seems to work for a second (light turns pink) and then the device resets itself again and all the lights display. A video is attached below, but before I send it back for being dead on arrival, has anyone got any suggestions?
Dissappointing as it's my first Mikrotik device but perhaps I just got a dud?
