Hi basically I just did the antenna mod where you replace the stock antenna with sma connectors so you can attach whatever antenna you wish. I was very carefull as well but now after putting it back together my controller does nothing. No lights or anything. I have put it on charge and still nothing..... I did post this is the mavic mini hardware mod section as well sorry for the double post. I have only had it for around 2 weeks so I'm panicking thinking now it is dead? I'm not sure what is wrong or if someone has had this problem and fixed it. Any help will be so much appreciated. Thank you
