I've recently got hold of an edev switch, which has been factory reset by the previous owner who wanted to use it as a retail switch but failed. As it stands it's just a nice collectable, as it can't do anything without devmenu installed or the correct/newer sdk. I've tried the 2016/2017 sdk...
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
