After fasthax / safehax I finally decided to do it since cubic ninja took a too long time to arrive (When I did fasthax/safehax cubic ninja arrived the next day) I went to mii plaza and saw there was an update. I tried to update but got error 009-6106. I tried to do it through eShop but got error 007-6106. Is there any fix for this? I read something about formatting but I don't want to lose any data. If I need to format, is there a way to backup data and format or is there any other solution?
