I was trying yo do a factor reset of a Deco E4 2 pack system, i used the reboot switch, i think the Main node was reset normally, but the same procedure can not work with the second node, after i power ir ok, the light got red permanantly for dime seconds, then the right LED turns down, while the red light is ok, i can see the old wifi network.

Please your help to do a factory reset of the non Main node with the switch buttom.
