So I received a soft brick after running tiny format and using sysDowngrade. Updated to 11.2 using recovery. Because Exidia stays on the SD it remains there after tiny format. Once I was back on 11.2 I used Exidia (dgTool) to restore the backup to 11.0 this is why it says to make backups. Then I...
although i ended up accidentally changing my nand with no way of going back bc i didn't know you needed a gamecube controller to restore it (i have a wii minus/1.1, which doesn't have gamecube controller support)
and if i find the sd card i have my NAND backed up on, i can not only restore the NAND if i solder the right part in, but i can also put my NAND on dolphin, then i can play dolphin online, like PMEX Remix or MKWii Riibalanced
