Thats hardly possible (especially regarding hardware), it was your own fault buying an outdated DM520 instead of newer Amlogic based hardware.
My decision wasn't just about the DM520. Even if I had chosen a newer Dreambox model, the overall ecosystem, software support, and community engagement were key factors in my decision.
Hardware alone doesn't make a device superior if the software development and support are lacking. I prefer to move to a platform that aligns better with my needs.
