Thank you for your feedback

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.

Log into OS shell as root.

Enter:

/usr/sbin/hwec_cmds -secure_boot set 00
/usr/sbin/hwec_cmds -boot_mode set legacy

Reboot the system.
After that, proceed normally with the reboot.
