I feel completely inept right now.
Just got my WiiU Super Mario & Luigi Deluxe Set with a firmware in the 4s I believe. I updated to 5.3.2 via Mario Party 10, then spoofed to 5.5.1. No problems doing any of the above.
I'm stuck completely on getting any eShop titles to work. Every time, I move the contents to SD/install, put into WiiU, run browser/WUP, run browser/WUP, back to home and get 0xFFFFFFFF error every time. I've tried 5 different games: Super Metroid, Super Mario World, Donkey Kong 64 & Ocarina.
I've used NUSGrabber cmd line and NUSGrabber GUI 1.7. Had no issues with cmd. My GUI only populated fully like twice, literally has never listed regions, and downloads previously selected titles constantly: it straight up doesn't work.
I've tried Euro versions and USA version of games. Latest one was 0005000010108F00 (Super Mario World). I'm at my wits end. What the hell am I doing wrong?
Not a complete noob to this scene, opened up my Wii, DS, PSP & Vita with minimal issues. Please help. I'm sure it's something done. Bonus points if you tell me what the hell is wrong with my NUSGrabber.
