NetOdin / Odin: The specialized software used to push firmware to Samsung devices. Computer: A PC to run the flashing software.

Warning: Manually flashing firmware carries a risk of permanently damaging your device. Ensure your battery is at least 50% charged before beginning.  Wired Flashing and Disassembling Samsung Gear S2
