This is the latest version I have at the moment drive.google.com/file/d/1epamw3L7YP2NL6QqMYkQqRcCDxY3UhXr/view?usp=sharing
Please note - new flash tool included.
If you already have V-Com drivers installed you are good to go.
Our YT Channel has videos ( www.youtube.com/channel/UCPt33KEKqPJfxFTf7CaKcFw/ ) for flashing and there are many more available on the web.
Please make sure you know what you are doing before you try this.
I have a zeblaze thor pro with mt6739 chip and flashed this firmware. It has a bug. The screen brightness is too low and even with adb, I was unable to adjust it brighter. The watch is only for use by night. I falshed it twice, without any result. I don’t recommend to use this firmware unless there is someone who is able to repair it. 
same BUG with brightness, please some one backup stock system.img file and upload here, can`t see any think with this FW
