Lem 8 Z29 Firmware

Hi friends, I have a Lemfo Lem8, Build number Z29-A-V1.2. My question is how can I upgrade the firmware and if so how do I do it. I’m sorry, but I’m not very good at that. I’ve read some tutorials but I’m not sure which is the best for now. Do I have to root the watch? Thanks for your understanding and help.

Thanks a lot for the answer and for the advice!
