# Samsung Odin
Samsung Odin is the canonical name used in this archive for the host-side Samsung firmware-flashing utility and protocol family referenced by the notebook spelling “Oden.”
## Stage placement
Odin is a front end at the host. The device bootloader remains the authority that accepts or rejects images based on signatures, model and partition compatibility, binary revision, rollback state, and lock policy.
## Evidence to preserve
Record device model, firmware package and hashes, Odin version, AP/BL/CP/CSC slot mapping, bootloader and binary revision, download-mode status, lock and FRP state, Knox status, and the complete flashing log.
## Evidentiary boundary
The presence or use of Odin does not establish that unofficial firmware was accepted, who initiated a flash, or whether the action was authorized.
