Heimdall is a cross-platform open-source tool suite used to flash firmware (aka ROMs) onto Samsung Galaxy S devices, developed by Benjamin Dobell at Glass Echidna.
Heimdall follows the naming scheme (i.e. Norse mythology) of Samsung's leaked flashing software, Odin, and uses Odin's protocol to interact with Samsung devices.
