Default Flash counter doesn't reset!

Hi, I have a problem with my S3. I don't know what's going on!
I can't reset my flash counter with TriangleAway anymore. Tried and retried, but nothing!
Before you ask me, I am on vanilla stock XXUGMK6 ROM, stock Kernel and stock recovery. SuperSU is updated to the latest version.
