Reliability problems with Xiao?

Thank you very much for your reply 0hotpotman0!

I’m not an advanced user so i would like to undertand 2 things:

  • The booloader in the link is the official one from Seeedstudio?
  • This bootloader will fix this problem?

Because I don’t want purchase other accessories to have the same problem after some days.
So if the answer is yes to both, do you have a step by step guide with cheaper programmer? i don’t have a raspberry and i don’t want purchase it just to fix a Xiao’s problem.

Thank you.
