try flashing the software old or latest without marking the BL file "BootLoader" in odin... and for csc pick home csc... its a real slight chance.

it never works that easy , only combination or gsi custom roms which requires u5 or 1 for combination , especially if you are on the latest binary , i really want to know if you can anyhow downgrade without these two like with softwareboxeftpro or something.

it actually worked for me more than 2 times, bootloader blocked its own replacement, so i just replace others and hard reset, i don't know if it works for everyone i just said what i already tried more than once, but not always success.

What binary are you on ? If you are on binary 5, you can downgrade

Well, when i tried it(s7/u7) it gave me the infamous smartswitch erm cyan screen whenever you boot no way back but to flash the current official binary again with odin.
