    Does this work with 512MB RAM devices? I wonder if Microsoft changed the update system, because so far it was not possible to update devices like Lumia 530 by joining Insider Program, even if you changed registry values. I think once you join Insider Program hardware (or some kind of unique ID) is also a requirement, while the “normal” updates from Current Branch (the public one) only uses model description that you can trick via registry as described on the article.

      Should work on 512MB RAM devices. This trick simply changes any phone to a Lumia 950 – it is eligible for all upgrades. However, W10M on 512MB RAM is buggy.
