Aegis Legend 200W "Coil not detected"

[donseeland]

I quit smoking and tried vaping for 2 weeks now and I love it. I have an Aegis Legend 200W and Geekvape Zeus Dual RTA. Then I bought the Drop Dead RDA which worked fine on my Aegis Legend. But when I switched back to my Zeus Dual RTA, it says "coil not detected". I tried the Zeus RTA on my cousin's mech mod and it worked fine. I updated the firmware on the mod and changed coil on my RTA but it still won't work. Would appreciate any suggestions guys. Thanks

Dirty 510 pin or threads?
Is the pin in the mod still popping up to meet the atomizer? Try wiggling it a bit with a pin or small precision screwdriver.
