Boot slot changed

What happened?

The printer is displaying the message: The printer has booted from an alternative slot due to failed boot attempts using the primary slot. Update the printer with up-to-date firmware ASAP to recover the primary slot. This usually happens after a failed update, or due to a hardware failure. Printer settings may have been reset.

Error name: Boot slot changed 

Error code: #10601

How to fix it?

Try to flash the firmware again. Try to avoid using OTA flashing as your network can be a factor. If it persists, it may indicate an issue with the on-board eMMC storage and the board may need to be replaced. If so, please contact support.
