I got my Wii U in 2022 with Tiramisu and WUP installer GX2 installed on. I downloaded some games and it worked fine, but when I tried to download more the progress bar froze, but WUP installer was still running (the bubbles in the background and the music kept going). I then tried to install the Aroma environment and downloaded Nusspli. Instead of freezing it gave me instead the "Permission error (read only filesystem?)" error and when I returned to the Wii U home menu it told me that the USB drive was write protected (The drive has a Y cable). I tried everything! I formatted my Wii U and the SD card (SanDisk 32gb) a lot of times, and still haven't found the problem! It's been 2 years!!
