    Wii Freezing, Even After NAND Reformat

    Please help...my Wii is posessed and I'm out of ideas on how to fix it. I have moderate experience with Homebrew, extensive computer experience, and have been a software tester. I mention the bit about software tester because I've used those skills to methodically try for weeks to pin down what the exact problem is -- without success.

    First, here's what's wrong: About 50% of the time, immediately after starting the Wii and clicking to accept the safety info screen, the Wii freezes. Occasionally, I will be able to start a game, only to have it freeze during gameplay. And even less occasionally, I will be able to play for some time without errors.

    The errors started about a month ago with an occassional message immediately after boot stating that the Mii Channel could not be loaded. After clicking to acknowledge the message, the Wii would freeze. The only way I was able to get past this was to leave the Wii unplugged for some time, then try again (possibly indicating a power supply issue), however even this was not successful all the time. Nothing had changed on the Wii for months with the exception of several new games -- no system updates and no tinkering with Homebrew.

    At this point, I decided to try to fix the issue by restoring the original NAND backup I created when I installed bootmii/Homebrew. Unfortunately, due to either computer gremlins or (more likely) my mistake, my original NAND backup was deleted. Yippe...easy solution not available. Thankfully I do have boot2 bootmii installed.

    So, as my second choice, I decided to try to fix the issue by trying to reformat the Wii. In my mind, there wasn't much other choice. Unfortunately, the reformat essentially got stuck at some point and I had to stop it by powering down. Of course, this messed some things up and entering in some of the menus now caused the Wii to freeze. Essentially, getting close to a partial brick.

    After reading on this forum about NAND Formatter, I hesitantly used it to reformat the NAND completely. After formatting, I used the LEGO Indiana Jones disk to install 4.1U then did an upgrade to 4.3U through the Wii menu. I purposely did not copy any of the original Miis back since I was suspicious of them (after the original Mii Channel error). My Wii Shop information remained even after the NAND formatting and I have been able to reinstall any previously-purchased games without problems. I have a NAND backup of this configuration.

    Unfortunately this didn't help completely. I no longer have the Mii Channel error messages and the errors caused by the partial Wii system reformat were fixed. However, the Wii still freezes ~50% of the time immediately after boot (with no error messages).

    After more forum reading, and convincing myself that it was a bad power supply, I tried a new PS, which didn't make any difference either.

    I can turn on the Wii with the remote, so it's not a bad Bluetooth module. And wireless works, so it's not a bad wireless modem. I've tried booting into "Maintenance Mode" with no effect either.

    I do not currently have Homebrew or any custom IOSs, themes, channels, etc installed with the exception of boot2 bootmii.

    At this point, I'm out of ideas. I'm actually considering removing bootmii and sending it to Nintendo to fix, even though there's a chance they may find some trace of Homebrew and refuse to fix it. Either that or buy an old Wii off eBay/Craigslist. Either way, I'm trying to save the investment in Wii games I've purchased (which granted isn't tremendous only ~$50). I'm guessing possibly something hardware related, but I'm not sure.

    Any help anyone could provide would be *greatly* appreciated. Please let me know what logs, etc would be useful in sharing with the site if anyone is generous enough to take an interest in my issues.

    Thanks in advance for any help...

    From the whole story, I think it's a hardware problem. Sending it to Nintendo won't help you: they can tell it has been tampered with.

    Thanks for the response. Two questions if you don't mind...

    1) Can Nintendo detect Homebrew even if the NAND has been reformatted? I know in the thread I read, the author mentioned that his reformatting solution does change the file permissions and that Nintendo could possibly view that as unauthorized modifications and could refuse service. Is this why you mention that Nintendo wouldn't help me?

    2) Do you know if third party service centers or Nintendo Authorized Repair Centers that look the other way when it comes to Homebrew? I suppose an option for me would be to find a service center that wouldn't care what softmods have previously been installed. Any suggestions from anyone that's had to have their Wii professionally serviced?

    EDIT 7/5/11 (had one more question I thought of...)

    3) Are there any guides on Wii hardware debugging? I've searched the forums and can find snippets here and there about how people have replaced various components, but no overall guide. Based on my reading, it's not the bluetooth module, WLAN adapter, or DVD drive. I'll be checking the fan this evening to see if overheating is an issue. Other than those components, what is easily user-replaceable? I don't mind disassembling the Wii to replace a fan, but would like to avoid major components like the motherboard. At that point, I might as well just buy a used Wii.

    1) Yes, they can.
    2) I never looked into this, but I think there are.
    3) I never looked into this either.

    Bliepo, thanks for your quick responses. Since it's something that sounds like it's beyond my ability/desire to fix, I just bought a used Wii on Craigslist for the same price Nintendo *might* have fixed it (assuming they ignored any Homebrew evidence). Thanks again.
