An electronic device according to various embodiments of the present invention comprises: a first memory including a boot area, a kernel area, and a recovery area; a second memory configured to load data corresponding to at least one from among the boot area, the kernel area, and the recovery area included in the first memory; a communication module; and a processor electrically connected to the communication module, the first memory, and the second memory. The first memory includes instructions that cause, when executed, the processor to: download data in the first memory through the communication module; when there is a request for updating the downloaded data, perform rebooting; when performing the rebooting, confirm whether a new version of recovery data is included in the downloaded data; and when the new version of recovery data is included in the data, update the downloaded data on the basis of the new version of recovery data. Thus, by reducing procedures unnecessarily repeated in the process of updating data, it is possible to rapidly and easily update data. Additionally, other embodiments are possible.
