Default G900M - Problem with OTA update

Hi.

I don't know if someone can help me, but I really don't know what to do with this problem.

I bought one G900M (version from Brazil) on the release date and after a few weeks I install a custom rom and the TWRP recovery.
The problem is: I tried to go back to the stock ROM, but I still have the recovery with the CUSTOM "mark".

I tried to re install many times, do a wipe/format from the recovery, with no success.
I always receive the message when I try update the phone by OTA what say "The operating system on your device has been modified in an unauthorized way. Try downloading...

I appreciate any help.

You tripped Knox when you rooted. There's no way to undo this.

But I'm not talking about Knox. I'm talking about the OTA update.
I reinstall the original firmware, stock version. Should work, no? Or Samsung changed the things again?
