Firmware on the 8BitDo Pro 3 updates through 8BitDo Ultimate Software (V2) over a wired USB-C connection; Bluetooth and the 2.4G dongle cannot flash firmware. The updater enters upgrade mode automatically, so no button combo is needed. To use the Pro 3 on Nintendo Switch 2, the console must be on system version 20.1.1 or later; a 2025 firmware update (v2.0) also added shake-to-wake for Switch 2.
