sadly, no luck. For the themes, I also tried Themely but it reverted back to the default white theme after restarting.
I will also try formatting the sd card I'm using.
Hi, I just updated my Luma3ds to 7.0.5 and Youtube was just stucked in the Nintendo 3ds screen, Pokemon Moon crashes and themes (CHMM theme and the default red theme) doesn't work after installing/applying and after you restart the console. Any ideas on how to fix this? Thanks
