Hi Cyril,
I am glad you are enjoying this build.
Right now I am not at home with my buildmachine, which is in desperate need of some hardware upgrades. I will only be back at home with my upgraded machine towards the end of the year.
I hope, by then, /e/ will have released their updated sources for android 12 as there are way better nd up to date devicetrees for this device based on android12.
