Troubleshooting

You will discover why your atfs device will not start, or is showing an error, and how to resolve it.

• Is the device working? — check whether the device is actually unhealthy, with or without a serial console.
• No error file at all — what a missing LAST_FATAL_ERROR.md file does and does not tell you.
• Read LAST_FATAL_ERROR.md — find and interpret the error file, if one exists.
