How can I recover the F405 V4 if a wireless firmware update is interrupted?

If a wireless update fails, the FC may become unresponsive. To recover, connect the FC to a PC via USB while holding the physical BOOT button to enter DFU mode. Use the Betaflight Configurator on your computer to flash the correct “SPEEDYBEEF405V4” target. For future updates, ensure your mobile device remains close to the stack and has a stable battery level.
