Odinis a utility software program developed and used bySamsunginternally which is used to communicate with Samsung devices inOdin mode(also calleddownload mode) through theThor (protocol).It can be used toflasha custom recovery firmware image (as opposed to the stock recovery firmware image) to a SamsungAndroid device.Odin is also used forunbrickingcertain Android devices.[2]Odin is the Samsung proprietary alternative toFastboot.

There is no account of Samsung ever having officially openly released Odin,[3]though it is mentioned in the developer documents forSamsung KnoxSDK[4]and some documents even instruct users to use Odin.[5]Some other docs onKnoxSDKreference "engineering firmware",[6][7]which presumably can be a part of theKnoxSDKalong with Odin. Publicly available binaries are believed to be the result of leaks. The tool is not intended for end-users, but forSamsung'sown personnel and approved repair centers.[8]

Usage

[edit]

Although none of the publicly available downloads are authorized bySamsungitself,XDA-Developersconsider the files offered on their Forum (Patched Odin v3 3.14.1 for windows) (Odin v4 1.2.1 for linux) the safest option.

For the usage of Odin, the phone needs to be in Download mode. For this, some key combination need to be pressed, such asPower+Volume Down+Home,orPower+Volume Down+Bixbyfor later models.[9]
