The Weirdest Thing Happened

[RileyIssKing]

So I was rooted and tried flashing back to stock after a bootloop and then the weirdest thing happened....Odin completed all of the steps and my s7 started downloading in download mode and everything completed successfully and when it rebooted... it looked like NOTHING CHANGHED. The only thing different was that the 'custom' with the unlocked padlock on the boot screen was removed and super su was telling me there was no binary installed. I used root checker basic and I am unrooted so did it work? It did this 2 times after, I tried again... is this common? I've flashed stock many times before but never has it ended up like this
