@rotigoos, I am sorry to hear that, but there is no technical way to reuse a license. I am working with my Pis every day for over 3 years now and not a single one of them died so far. I believe you that this can happen, but there is no way for us to check whether it is true or the user just tries to get another license for free. Or if the Pi was intentionally broken. This is why we are currently reducing prices for personal use (see our main page).
Nevertheless, we always tryto help our customers. Could you please write an email to our support@emteria with a description of circumstances under which your Pi died? Please include some information about how it was used and which safety measures you have taken to prevent hardware destruction.
