Heimdall Benjamin Dobell

Heimdall is a cross-platform open-source tool suite used to flash firmware (aka ROMs) onto Samsung mobile devices. Heimdall connects to a mobile device over USB and interacts with low-level software running on the device, known as Loke. Loke and Heimdall communicate via the custom Samsung-developed protocol typically referred to as the 'Odin 3 protocol'. USB communication in Heimdall is handled by the popular open-source USB library, libusb.
