Flashing Procedure

• Extract the firmware zip and open SP Flash Tool V6.

• Ensure the operation dropdown menu is set strictly to "Download Only".

• Under the Download-XML field, click Choose and load flash_signedDA.xml from the firmware directory.

  Under the Authentication File field, click Choose and load authsv5_jagar.auth from the same firmware directory.

• Check the Auto Reboot box.

• Optional Step to preserve data: In the partition table checklist, scroll down and de-select the userdata partition.

  Unchecking this prevents SP Flash Tool from overwriting the partition or destroying existing encryption metadata.

• Click the Download button in SP Flash Tool.

• Connect the DC-1 over USB to initiate the flashing sequence and allow the write process to finish completely.

• The unit will reboot automatically upon completion. If it does not, hold down the top-right power button until the Daylight boot splash appears.
