Method 1: Connecting through USB-cable (step-by-step instruction)
The most obvious method is to use the original USB Type-C cable (or quality cable). However, even here there are pitfalls. First, the USB port on the computer must support USB 2.0 or higher (there is no USB 3.0 on the Redmi 4X, so the speed difference will be negligible).
