Were you able to inject fusee.bin (instead of Hekate) like @Draxzelex recommended? The reason we want you to try that is it completely bypasses hekate and its configs on your SD card and boots straight into Atmosphere on Sysnand. It will prove/disprove any non-working components and clear the path for next steps…
“When you went to download Atmosphere from its GitHub page, there was another thing you can download called fusee.bin. Its a payload similar to Hekate. Try sending that instead of Hekate; its designed to automatically launch Atmosphere.”
When trying to inject fusee.bin I just got the same fetal error message I was getting before.
