2. I downloaded 12.0.0 (SD1A.210817.037, Nov 2021) fw version for Pixel 6.
3. I renamed file Radio-oriole g5123..................img to radinov.img
4. I put the file radionov.img in folder PLATFORM-TOOLS
5. I turn on usb debugging on my phone
6. I connect my Pixel 6 by usb cable to my windows 11 laptop.
