I'm on step 4, section IV of the guide, on O3DS XL. Everything went down successfully up until now, all of my backups match the sizes stated in the wiki (my original backup size matches Samsung's, the updates I downloaded from the guide match Toshiba's).
After dumping my OTP I'm now trying to...
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
