Gopro hero 11 black downgrade from 2.10 to 2.1

[HorvathAdam]

I'm reading in discussions that the firmware of newer GoPro Hero 11 Black cameras can only be downgraded as far back as version 2.12, and no further. This is also my own experience. My question is whether it's possible to downgrade from version 2.10 to version 2.1. Does anyone have experience with this? My question concerns the original factory firmware. The reason I'd like to downgrade the factory software to 2.1 is so that I can then install LABS 01.20.70.

Why? What feature are you missing in the newer firmware? And I have no idea, I have no data on downgrading.

Actually, I'd like to use the LABS_HERO11_01_20_70 firmware because it's the last LABS firmware that supports motion detection in photo mode. To the best of my knowledge, the 2.1 official firmware was the last one on which the LABS_HERO11_01-20_70 could still be installed. Now I might have the opportunity to buy a camera with official firmware 2.10. My thought was to downgrade the 2.10 to 2.1 and then install the LABS_HERO11_01_20_70. I'd like to know if anyone has experience with this.
