Hi,
I had SXOS on emunand in 9.0.0 version & my sysnand updated
Yes, thats the reason my switch is bricked, in some point I had CFW on my sysnad & use the Haku33 software to "clean" the console until the 17.0.0 update :(
When I first try Atmosphere I did it migrating the SXOS EmuMMC using Hekate...
