Here's my story:
A friend of mine gave his Wii (NTSC) to me on December 2009. He bought it on early 2007. A few months later, he instaled a modship (WiiKey).
When i got it, the version of the firmware was 1.9a and the video game was semi-bricked (the Opera settings problem..). He told me that i had to update the firmware, naturally, i tried to run 1,9s installation. I don't know if the update was succesful 'cuse when it finishes it says to press "A" button but the WiiMote (don't have GC or Classic) doesn't answer after the installation, and if i reset it begins all over again, leaving me no choice but turning the Wii off.
Well, he doesn't know how he semi-bricked his video game. I've been playing normally since i got it. Zelda TP, Mario Galaxy, Metroid 3, Tatsunoko VS. Capcom, Resident Evil: TDSC, CoD: MW and etc... just got a problem with his copy of SSBB, it gives me the 0001 (or 0002?) error screen. Last week i burned a copy of Monster Hunter Tri (PAL) and the Wii asked me to make the update, i chose not, afraiding of causing any more damages (in the end i was right to do so xP). So i began to research, and i got very useful information, but i'm still not sure in what to do next. I've burned a disc with the System Menu Updates USA v289 that i found on hackmii.com but it gaves me a "System fles corrupted" screen.
When i fix these problems i plan to install HBC on it, just waiting for the SD card. Another question of mine is if there is no problem on installing it on a system with a modchip and if will be ok to play online.
