What I am wondering is...
1) Are you using dongle to inject? Or modchip?
2) Are you launching fusee-primary from within Hekate? If so, there was an issue in a past version of Hekate that created problems with the SD bus clock. If you haven`t done already... Can you use very latest Hekate (or my Hekate mod called Switchboot) to try booting?
3) Cannot exclude hardware errors - or voltage drops... Just try something for me... Does the same thing happen with and without the joycons connected?
What did you tried to do?
Please, read what
