The flasher detects your device automatically, so you can't flash the wrong version.
The firmware is overwritten. ROMs and saves on the microSD card are not affected.
USB-C to USB-C cables are not supported. Use a USB-A to USB-C cable.
Only needed for testing or troubleshooting. A normal install does not need this.
Recovery skips the confirm step and re-flashes a stuck or restarting device the moment it is caught — no need to be quick. It uses the firmware selected above and still verifies the hardware first.
Flash your own .img file. The device is still detected, and a file larger than the chip is refused so it can't brick the device.
