Firmware updating method and electronic apparatus using the same

A firmware updating method for updating a main firmware component of an electronic apparatus electrically connected with a removable memory device, the method comprising:

• (a) performing a firmware updating procedure to update the main firmware component by using a firmware updating component in the removable memory device;
• (b) deleting the firmware updating component and then rebooting the electronic device if the firmware updating procedure is successfully finished, or directly rebooting the electronic device if the firmware updating procedure is unsuccessfully finished;
• (c) determining whether the firmware updating component exists in the removable memory device after rebooting the electronic apparatus;
• and
• (d) sequentially performing the steps (a) to (c) again if the firmware updating component exists in the removable memory device in the step (c).

An electronic apparatus, comprising:

• a memory module storing a boot code component and a main firmware component;
• and
• a processor configured to perform a firmware updating procedure to update the main firmware component by using a firmware updating component;
• wherein the processor is further configured to delete the firmware updating component and then reboots the electronic device if the firmware updating procedure is successfully finished, or configured to directly rebooting the electronic device by manual means if the firmware updating procedure is unsuccessfully finished;
• wherein the processor is further configured to determine whether the firmware updating component is presence after rebooting the electronic apparatus;
• wherein the processor is further configured to sequentially perform the firmware updating procedure again by using the firmware updating component if the firmware updating component is presence after rebooting the electronic apparatus.
