Help! I'm stuck on 11407

This means that Klipper is failed to start.

First - don't worry, you can still re-flash stock firmware, then attempt to reinstall Duck Pro.

You need to re-flash stock firmware and then try again if you want.

Links to the stock firmware:

• 2.3.5.3
• 2.3.3.9

Place it as update.swu in that folder with strange symbols.
