@Steve_Fox, I found out today that kospet has changed their firmware section and now the firmware for the vision is available as well (https://www.kospet.com/rom/KOSPET_VISION_V1.4_20190925(32+3).zip). I downloaded it and have now ported twrp for you (ported it from the one coming with prime_v2.3):
instructions:
- flash with sp flash tools in download only mode
- copy magisk manager to the watch and install
- use magisk manager to download magisk.zip
- reboot to twrp with the command “adb reboot recovery”
- install / flash the magisk.zip
