Not a firmware issue, but indicative of a grounding issue.

The current sensors are the coal mine canaries of your switch- they're the easiest path to chassis/earth ground for stray electrons, so they're the first to blow when there's a problem.

Ask sirhc, he'll bend your ear about grounding- l usually just recommend you search this forum for the word grounding and keep reading until grounding no longer looks like a word, there's plenty of good stuff around.

Anyway, you can RMA your switch if you like, we can repair this level of ground current damage reasonably inexpensively.
