    Abstract: A mobile device may be configured to monitor its systems and subsystems to detect a flashing command from a flashing tool or source, generate and store a flashing request value in a secure area of the mobile device in response to detecting the flashing command, send the flashing request value to the flashing tool or source, and send a notification message to a server computing device of a trusted entity. In response, the mobile device may receive a notification-response message that includes a secured flashing request value from the server computing device, and determine whether the secured flashing request value matches the flashing request value stored in the secure area of the mobile device. The mobile device may ignore or discard the detected flashing command in response to determining that the secured flashing request value does not match the flashing request value stored in the secure area.
