FAQ: Can I use 3.01VESC tool for 5.2 firmware? 

We don't suggest to use 3.01 VESC tool to do so, because when you use latest version vesc tool it will always jump out reminds to update new firmware, and also the 3.01 vesc tool is too much slow to be opened. 

Reminds:

If you're using Spintend remote Uni1 or Uni1 v2 with Ubox, no need extra receiver hooked in the Ubox, since it has internal receiver already.
