I doubt it is a hardware failure. There was a system menu (old) that did not display a version number in RM. Try sticking a game into the wii (in region) when you get to the black screen, let it sit for 30min, try that with all the in region retail games you have. Perhaps something nice will happen. This wii is region changed yes? You said it was Jap, was it region changed to Jap or from Jap to something else? I believe that the wii was region changed and the proper region select channel was not installed, then a system format was done initializing the region select channel which may not be there. This can also happen via an out of region disc update, but only on older system menu's to give this error at boot. Lets assume that the black screen is RM and it is working, try updating from a proper in region retail disc. Just do savemiifrii, then when you get the black screen, put in the disc and let it sit for 30min.
a friend of mine passed me a console with modchip only. No softmod ever done. i believe it's a console at 3.x version--- it's bricked for long -- after playing an out-of-region game disc !
power it on, the screen immediately shows the typical OPERA ERROR Message, without showing the Health Warning and without a need to press the A button.
blu-teeth module works fine, wifi module works fine. However, no way for me to get into Maintenance Mode, no matter what i tried with the GC controller or pressing the A_+_- keys all together. it seems the GC port is not working at all.
I checked the circuitry continuity of the GC port; and found no defect.
Tried to load in autoboot game disc, or MMM disc; but nothing.... just the disc keep on spinning.
Has anyone any idea ???
any suggestion would be appreciated, but not asking me to flash the NAND. :D
after re-reading thread #304, i intend to follow your words ..."Try sticking a game into the wii (in region) when you get to the black screen, let it sit for 30min, try that with all the in region retail games you have. Perhaps something nice will happen." any good, plz ?
