Odin (firmware flashing software)

Odin is a utility software developed and used by Samsung internally. It can be used to flash a custom recovery firmware image (as opposed to the stock recovery firmware image) to a Samsung Android device. Odin is also used for unbricking certain Android devices.[1]

There is no account of Samsung ever having officially openly released Odin, though it is mentioned in the developer documents for Samsung Knox SDK[2] and some documents even instruct users to use Odin.[3] Some other docs on Knox SDK reference "engineering firmware",[4][5] which presumably can be a part of the Knox SDK alongside with Odin. Publicly available binaries are believed to be the result of leaks.[6]

Heimdall is a free/libre/open-source, cross-platform replacement for Odin.[7] The name Heimdall, like Odin, is an allusion to Norse mythology; both Odin and Heimdall are among the deities of the Norse pantheon.
