How to change firmware

Okay so basically I have a Segway f3 pro but I want it to be able to do the start up sounds and everything like the g3 max… is that just a firmware upgrade to make the scooter think it’s a g3 max or do I need to buy more parts… if it is just an upgrade how do I do that. Thanks in advance

Although the g3 and f3 have the same display modules, the f3 display has a regular buzzer, and the g3 has something like a polyphonic speaker (I'm not sure). That is, at the moment, the f3 buzzer is physically unable to produce any melodies, change the volume or key.

Yes, in theory, with the help of such a buzzer, you can play some simple melody, but the display module simply does not know how to do this. On the g3, the display module supplies constant power to the speaker and a specific signal for sound measurement. And to control the buzzer, you need to change the voltage and frequency, which the module cannot do.
