Thanks @danxuliu for your great effort. It’s really inspiring to see your work.
@Stefan, we are in contact with @danxuliu (I am especially eyeing his work on TWRP) but please don’t get your hopes up too much. @danxuliu already explains the hurdles he faces and even if we join forces they might be impossible for us to overcome. Additionally, we don’t even have decided whether Fairphone can pour resources into such an endeavor.
