Note5: Impossible Downgrade

[Edember Ruazol]

Hey, I bought this Note5 sealed last year but it was shipped with Android 6.0 then I upgraded it a Nougat then I didn't liked the UI so I want to revert back to Lollipop because of the beautiful clock shadows and lockscreen effect. But in the process of downgrading through Odin, it says: SW REV CHECK FAIL.. (I forgot the numbers on it..)

I'm basically saying how to downgrade to a firmware with lower version of bootloader??

You don't if the phone is locked against downgrading the version of Android. There are hardware fuses in the phone - if one of them is blown, you can't revert back past a certain version. If the next one is blown ... etc.
