Hacking fortnite won't work without switch update

[Draxzelex]

i installed the atmosphere files on the sd card as shown in the tutorial.
When i start the switch (power and "+" button) i get into the SX OS, select options , payloads and hekate_ctcaer_5.5.7.bin
Hekate starts and i select launch > atmosphere CFW i get error "unknown pkg1 version hos version not supported or emuMMC corrupted.
When i select stock sysnand i get error "pkg1 decryption failed

How is the SD card formatted?

Sorry for the possibly late reply, but the problem is he's chainloading it via the SX menu. Obviously he has a Mariko Switch and updating even OFW to the latest firmware DOES break SX OS EmuNAND due to the fuses. The OP should use the SX Gear boot.dat to load Hekate. This is just for people wondering why and what's the solution as he already solved it in another thread.
