How to update Spacecraft-NX (HWFLY-NX)

Notes

• SX FW: If your SX modchip is not running Spacecraft-NX (HWFLY-NX), then please follow this guide instead to install Spacecraft-NX.
• No card reader: Not needed. You can access your SD card contents via USB without removing it from the Switch. See this guide for instructions.
• "HWFLY Toolbox" will not allow unflashable chips to become flashed. Unflashable ones have a BGA FPGA IC on the board. Flashable ones use a QFN FPGA.
