Update method (USB or SD)

  • Use an empty USB stick or SD card formatted as FAT32 or vFAT

  • Insert the media after the unit boots; the screen can go black briefly and the update continues automatically

  • After completion, hold the Settings button for about 10 seconds and open Software Version to confirm the new version

Important notes

  • Use stable power during installation. Many drivers keep the engine running to avoid low battery during the update.
