Got this Error to day after my little brother updated my switch to 9.0. I would appreciate any help. I have already restored all backups. will not boot to anything. I can still enter RCM and I can sill inject payloads and all that. However I cant access the system nothing after Nintendo switch boot logo if it even makes it that far. I have used multiple SD cards Samsung and the official Nintendo switch one. I have also tried exFat and Fat 32. I can post pics and vids if that will help thanks for just reading this.
