    Hi guys!
    I have an Galaxy note 4 locked to sprint, so i am trying to downgrade the OS from 5.1.1 to 4.4.4 so i can unlock it with the SSU unlock tool but every time i try it i get this error,
    SW REV CHECK FAIL : [aboot]Fused 4 > Binary 1
    [1]eMMC write fail : ABOUT.
    I have tried everything changing computers, USB ports , different cables, but seems like no way out of it .

    it would be amazing if someone could shed some light on this matter! also regarding the unlock if anyone has some ideas if it really works or not.

    I have attached some pictures and info about the device.

    Thanks !

    Most models have "hardware fuses" that are purposely blown during upgrade to prevent you from being able to downgrade. Your error message confirms that is the case for your phone.

    You could always call Sprint and ask them for the correct unlock codes...

    I have Note 2 from ATT, which is different. But I was able to downgrade from 4.4.2 to 4.1.1 using Odin v3.07.
    After Flashing when I inserted my MetroPcs card I got error #66M. I researched it online, and it said either corrupt
    imei or phone reported stolen. So, I took it to MetroPcs and it was activated by them.
