The provided adapter allows you to connect a Type-C device, or you can use a Type-C to micro-USB cable without the adapter. ^^ The EDL (Emergency Download) mode enables the EDL cable function, which triggers Qualcomm devices to switch to Qualcomm HS-USB QD-Loader 9008 mode. ^^ The HAR (Harmony OS) mode enables the Harmony OS cable function on Hi-silicon devices, allowing the device to switch to UART COM/Serial mode. ^^ Due to the variety of colors, you may expect to receive one of a black, red, or yellow cable (as shown in the image) in your package.
