When in UEFI Boot Mode (optional Secure Boot), the device cannot be downgraded to Legacy Only. If a Legacy Image downgrade is necessary (v5.0 and below), disable Secure Boot and change to Legacy Mode. Then the downgrade procedure can be done.

  1. Log into OS shell as root.
  2. Enter:
    /usr/sbin/hwec_cmds -secure_boot set 00
/usr/sbin/hwec_cmds -boot_mode set legacy
  3. Reboot the system.
  4. After that, proceed normally with the reboot.
