Abstract: A device comprises a first processor and a second processor, the first processor being able to execute a boot loader. The device implements a phase of boot-securing in the event of an electrical anomaly occurring while the boot loader is being updated, the phase of boot-securing being implemented by way of an emergency power supply source acting as a relay for a main power supply, the phase of boot-securing comprising the following steps: stopping (203) the current updating of the boot loader; and invalidating (205) the boot loader. The device implements a phase of delayed booting of the second processor, enabling to boot the device in a boot loader update mode if said stored boot loader is invalid.
