I have an N3DS with emuNAND and my firmware version is 9.5.0-28U. I already updated the Nver to -28X. I then did the whole backup emuNAND, Nintendo 3DS folder, and then formatted emuNAND. Set it up like normal and linked my NNID. I then restored my emuNAND bin and my Nintendo 3DS folder. The only problem that is even after using the guide to "fix" this error, I still get it when launching eShop from Hans.
