MODERATOR EDIT - this is untested by us so we cannot say if it ok or not. Flash at your own risk.
I have tried it and it works perfectly.
It is only for Lemfo Lem5 W618. Make sure you have this model before installing it.
I was sent the Lemfo firmware.

Unfortunately, the smartwatch does not start after taking the flash of this firmware
