EX6110 Red light all the time

[FFNETTO]

My WiFi Extender was working normally. Suddenly the Power light turned red and it is like this ever since. Reset, pushed everything and it just doesn't change. Have no idea of what should I do.

When you pushed reset, did you push and hold for 7-15 seconds while powered on? 

You can try recovering it with tftp or nmrpflash.
are you on windows? if so, follow this guide

just make sure you enable tftp

and here's a video walk through using a tftp client. Use the built in one for windows 10 though. the video is more of an example of how its done.
