Zeblaze firmware 20181218

Anyone know where I can find this firmware. It’s on my watch but I can’t seem to find it to download it so I can patch the boot.img , adb isn’t working for me , I should have putting the magisk.zip on the memory before I installed twrp .

Can you post the exact firmware version details that you have on the watch right now please?
You will find it in Settings, About Watch.

Should be all you need.
