Folks, good afternoon.

Unfortunately and suddenly my Nintendo Switch is showing the error code 2002-3999.
What were done to try to fix it:

a) Format my SD card (64 gigas) and put all files again (Ctrl C_Ctrl V/copy and past).
b) Instead of use ExFAT format i have change to FAT32/NTFS.
c) replace boot.dat and license.dat

Its had never happened before and sometimes the green light does not come on, only the blue light (from the Dongle).

I am using the NAND and Emunand (SXOS_beta_v3.0.4 / Nintendo Firmware 10.1.0.
Thanks for all.
