Default [Q] does odin reset the flash counter when you unroot?

like the title says, just wondering if odin resets the flash counter. rooted this phone for my dad a while back but now he wants it back to stock and since i am not very familiar with samsungs root/unroot processes i have no idea if it resets it or not. already tried triangle away but when i rebooted and then went back to download mode to check if it reset the counter it said the binary was still custom.
