Flash Global ROM Onto Chinese Band?

If I remember correctly, the Chinese version is the same thing as the later global release and it should not be necessary to flash a ROM, it should contain English right out of the box and more feature will come later with update over zepp life/whatever the app is called now

I'm not gonna risk it, since there are likely hardware differences too. October 3rd seems to be the likely global release date, so about a month away.
