Hi there

My main deco unit is solid yello LED. 

Have tried to reset but it does nothing and stays yellow. 

I visited the forum https://community.tp-link.com/en/home/stories/detail/672 and followed the instructions. 

When I get to reset and turn on Deco the led stays solid yellow, and then the LED turns off after about 10 seconds. It allows be to go to the firmware upgrade page 192.168.0.1 but the firmware upgrade fails. It states I may have used wrong firmware, I tried both available ones in the download section. 

Where do I go from here? 

Thanks
