This guide just saved me, I just fixed my "half bricked" Japanese Wii U. I just want to say thank you for taking the time to gather all this information and displaying it in this fool proof guide for the community.
Hi there, I've recently got a japanese wii u for modding purposes but as you saw in the title it's having some problems. The thing when i plugged it on everything worked great until i tried to begin with the homebrew process and the internet browser would not work. It displayed the error code...
I may try the new ram site, and download more RAM to my Switch. Not sure if ddr3 is the right ram
for it tho. Edit- no it uses floppy Ram, just like @AncientBoi
