Ravi, It sounds like you are suggesting a private modification of OpenCore. Is that correct? If I modify my copy of the download manager to pass the queryInterface, then the modification will need to be reinstated each time there is a new release of opencore that changes the download manager. I have been operating under the principle that new nodes can be added without changing any portion of OpenCore or Android. I am trying to use the download manager as the master node in the pipeline which loads my own parser node. Am I misunderstanding your suggestion?
