I recently bought a second-hand Wii U, that was bricked. I was able to uninstall Coldboot Haxchi and factory reset the system. Afterward, I installed Tiramisu and the Wii U end of things is working fine. However, I am not able to load vWii / Wii Mode or Virtual Console Wii / Gamecube Games at all. Every time I open Wii Mode it shows the Health and Safety Information, sometimes I am able to press A. After a few seconds I hear the DVD drive, the power LED flashes once and the system turns off (Red Power LED). I guess that the previous owner also made some mistakes installing Homebrewing in vWii. I obviously don't have a working NAND backup, as it was already broken when I got the Wii U. I also tried vWii Decaffeinator multiple times (Aggressive and Regenerate setting.txt) however I still have the same problem.
I hope that someone is able to help me, would be great to use my Wii U to its fullest. Thank you!
