I had the nimbus app on my 2DS for a while and it worked just fine; however, recently my SD card gave out and I had to make a new one. Now when I try to launch the Nimbus app it goes to a black screen. I already set the luma3ds game patching flags. I cannot update any games, (error code 005-4270) so I assume it is stuck on the pretendo mode if it’s working at all.
The app has decided it will work now and i can update games again so i don’t even know
The black screen is normal and intended behaviour. You need to switch to Nintendo Network to update games, Pretendo does not have any plans of supporting eShop
