I remember it being a sort of hacky way to update to 3.65 and retain 3.60 hacks, but is there any difference in the end? Would it be any cleaner starting from a fresh 3.65 OFW and installing h-encore+enso instead?
From looking at the source, the Enso recommended in the h-encore readme is just a 3.65 port of Yifan's 3.60 Enso, so without the "factory reset all you want, it stays active because boot_config is not in ur0"
