Hello mr. andrew. I have the same case. I know that people are not really using nintendo WII nowadays.

Just bought a 2nd hand WII, and without any knowledge, I had connected the WII unit to my Wi-Fi and suddenly it asked to update. So then I did my update, after some times, stopped, and suddenly the GREAT ERROR 003 showed up.


Please, if you received this reply, do contact me at 0168324901 or mail be at abuhassannoh86@gmail.com.

I live at Kota Kinabalu, and I do not know if there's any local shop here that can help me to solve this problem.

Thank you.
