The Nova 2 Lite updates either through the GameSir mobile app (connect via Bluetooth or USB; iPhone users connect in Android mode) or with GameSir's PC Flash Tool. For the PC route, close all GameSir software, hold M + X + B while plugging in to enter update mode, then Install Firmware. The 2.4G dongle is flashed separately by holding its pairing button while connecting. Only install firmware made for the Nova 2 Lite — wrong firmware can brick it.

FAQ

Why must I close GameSir Connect first?
Other GameSir software can hold the device and block the Flash Tool. Close everything, then enter update mode with M + X + B while plugging in.
Is Nova Lite firmware the same?
No. Nova Lite and Nova 2 Lite are different controllers; installing the wrong one can brick yours, so match the model exactly.
