UPDATE:
@mozbius commented and shared this link on how to restore the deleted config file. https://forums.wyze.com/t/wyze-cam-v3...
And some of these guys in the comments have also been able to reload the firmware onto the camera with the MicroSD card. https://support.wyze.com/hc/en-us/art...
My Wyze Cam v3 died on me. In the app it shows this message. "Device is offline (error code 90) Please check your internet connection or power cycle the camera." I also tried to factory reset it by pressing the Setup button for 10 seconds but the red light stays on and never starts blinking.
