    • Yes this is Marshmallow OTA file. Don’t get confused with numbers S121 is Indian variant and S205 is global variant of k3 Note

    • Use this combination “Volume UP+Volume Down+Power Button” to enter into Recovery mode

    • Yes some time it stuck on 49% but wait for some time to complete the process.
