Hi, I have just bought a K2 and trying to get it work with no success so far. Specs: SD 256GB, iPhone 8, Win 10. I have already solved the fat32 formatting issues (not available under Win10), saved the latest firmware to the SD Card, inserted, and the firmware update started with the camera icon blinking red. Nevertheless, it does not finish, it keeps blinking periodically (with the WIFI and the video camera leds). No Wifi signal is detected, I have already tried the airplane mode, the network reset on the phone. My notebook does not detect the wifi signal, either. I am powering up the DVR from the 1Amp USB socket of my notebook. Any idea how to fix it?
