Abstract: In a method of recovering a bootloader in a mobile electronic device, a bootloader recovery signal is transmitted from a bridge board to the mobile electronic device. The bridge board includes a first internal path and a second internal path. The mobile electronic device includes a third internal path and a fourth internal path. The bootloader recovery request signal is transmitted based on the first internal path and the third internal path. a boot mode of the mobile electronic device is changed based on the first internal path and the fourth internal path in response to receiving the bootloader recovery request signal. Bootloader recovery data is transmitted from a host device to the bridge board based on the changed boot mode. The bootloader recovery data is transmitted from the bridge board to the mobile electronic device based on the second internal path and the third internal path.
