i have a unpatched switch with 6.2 clean Sys and 8.1 Emunand Sx os, the question is that i want to stay with my firmware 6.2 because in the future a new exploit will work up to 7.0 without jig (i know that autorcm can ban the switch). it's possible to create a clean emunand for online? i have to use sx os or atmosphere for this clean emunand?
