An apparatus for determining an abnormal Read Only Memory (ROM) update in a portable terminal, comprising: an update start counter for counting a quantity of times a ROM update process begins; an update finish counter for counting a quantity of times a ROM update process is finished; and a ROM update unit for increasing a value of the update start counter when a ROM update process begins, and increasing a value of the update finish counter when the ROM update process is finished, a controller configured for controlling commands and communications between at least the ROM update unit and update start counter and update finish counter, wherein, when the portable terminal abnormally operates, the controller controls a debugger in which the ROM update unit loads the values of the update start counter and the update finish counter, and in a debugging mode compares the loaded values of the update start counter and update finish counter in order to determine whether or not a user has intentionally disabled a portable terminal by booting or disconnection after a ROM update process begins.
