Information processing apparatus and firmware update method

An information processing apparatus comprising:

• a hardware processor that:
• executes an installed firmware of a first version;
• stores history of execution of execution processes;
• acquires a set of firmware of a second version that is newer than the first version and verification state information that indicates progress of verification for each of a plurality of processes defined by the firmware of the second version from a server;
• and
• installs the firmware of the second version to update the firmware of the first version with the firmware of the second version, wherein
• the verification state information indicates progress of verification that an error does not occur during execution of each of the plurality of processes, and indicates either a completed state where the verification is completed or an unverified state where the verification is not completed,
• the unverified state comprises an error state where an occurrence of the error is confirmed, and the hardware processor further prohibits installation of the firmware of the second version when the verification state information that makes a set with the firmware of the second version indicates the error state for an execution process specified by the history.

A firmware update method comprising:

• executing an installed firmware of a first version;
• acquiring a set of firmware of a second version that is newer than the first version and verification state information that indicates progress of verification of each of a plurality of processes defined by the firmware of the second version from a server;
• and
• updating the firmware of the first version with the firmware of the second version, wherein
• the verification state information indicates progress of verification that an error does not occur during execution of each of the plurality of processes, and indicates either a completed state where the verification of a non-occurrence of the error is completed or an unverified state where the verification of the non-occurrence of the error is not completed,
• the firmware update method further comprises setting a settability state of an unverified process, out of the plurality of processes, to a disabled state where a user cannot make settings to allow execution of the unverified process, and
• the verification state information of the unverified process indicates the unverified state.

A firmware update method comprising:

• executing an installed firmware of a first version;
• storing history of execution of execution processes;
• acquiring a set of firmware of a second version that is newer than the first version and verification state information that indicates progress of verification for each of a plurality of processes defined by the firmware of the second version from a server;
• and
• installing the firmware of the second version in order to update the firmware of the first version with the firmware of the second version, wherein
• the verification state information indicates progress of verification that an error does not occur during execution of each of the plurality of processes, and indicates either a completed state where the verification is completed or an unverified state where the verification is not completed,
• the unverified state comprises an error state where an occurrence of an error is confirmed, and
• the firmware update method further comprises prohibiting installation of the firmware of the second version when the verification state information that makes a set with the firmware of the second version indicates the error state for an execution process specified by the history.
