Update firmware

I tried to upgrade my ortur laser and I use pdf instructions, I successfully open the ortur folder but when I put the new file, the folder is closed and I recive a message that the drive is not connected, I work with win 10 , and when I trying to check the version in lightburn I see in the device “grbl” insted ortur
Please help

Ortur uses GRBL firmware, so seeing GRBL as the device is expected.

Okay, why do I see in the tutorial videos that “ortur” appears?
Why i can’t update firmware? I think I have 1.1 version
