Security Brom mode is a protection mechanism that prevents unauthorized access to the system by limiting the ability to reset or flash the device. It is triggered when there is an attempt to perform these actions without proper authentication. Brom (Boot ROM) is a preloader software in Mediatek-based Android devices that loads before the firmware, and it is responsible for initializing the hardware and booting the firmware. Therefore, when security brom mode is activated, it can make it difficult to unlock the pattern, pin, password, and FRP on the device.
