I'm using the latest atmosphere sigpatches. does fusee-primary have sigpatches? I can't boot into fusee-primary because it crashes everytime I try to push the payload.I believe you might be using sigpatches from fusee-primary but launching into Atmosphere with Hekate, and that's why you can't install NSPs. About the issue booting with fusee-primary, make sure your CFW and your fusee-primary.bin files are updated, that also might be the issue.
