The Wii only received its 4.2 update the other day, but already the Internet's alive with reports it's causing machines to stop working completely, with many popping up on our very own forums. The update's major purpose was to remove the Homebrew Channel from consoles, as well as protect the Wii more robustly against piracy, but it appears it's had an unintended negative effect on legitimate gamers too.
Nintendo hasn't released an official statement yet, but admin NOA_TECH_JAN did have this to say in the company's official tech forums:
Some of you have reported problems with your Wii console after updating to the Wii System Menu 4.2. The symptoms most people are describing usually occur when the Wii has been modified. However, some of you also mention your system has never been modified.
We'd like to help get your system working properly again. If you're experiencing problems with your Wii console after downloading Wii System Menu 4.2, and you believe your system has not been modified, please give us a call. If we find that you have a normal system and the update caused your system to not work, we'll repair it at no charge.
Please call our Customer Service Department at your earliest convenience, 1-800-255-3700. We are open 6 AM to 7 PM, Pacific Time, 7 days a week.
Hopefully Nintendo will soon put this right with a future update.
