Is this compatible with MHI2_US_POG11_P5251?

Just got a 2024 718 Cayman and wondering if this works with FW version MHI2_US_POG11_P5251 or if I need to find a way to downgrade.

Thanks!

It's not working with my 2024 Boxter with P5250 either.
And as far as I know, downgrade of these new hardware units without DVD player is not possible.
I'm in the same boat...

Same issue with the More Incredible Bash Github repo.
It looks like the developers aren't interested anymore in creating a solution for the new headunits Porsche currently uses.

I have a backup of the firmware of my unit, but need somebody to take a look at it.

is there a developer guide?
