Yellow Lights, no rc signal help

Hi, all I have a DJI 3 Advanced updated the firmware to the latest today, and the drone went successful but the GL300B controller isn't updating or doesn't appear to be. The light won't go blue... if I update via USB stick or SD card, or from drone neither work and the text file doesn't update. If I try from the app, it shows unkown firmware. So I'm assuming something gone wrong.

Anyone have some ideas?
