There is also an error 002 fix in your loader's option.
I recently helped a mate with Softmodding his Wii, and after the Dogeggs 3.1-4.1 guide was followed to the letter. We installed a copy of USB Loader GX and plugged in my HDD to test the Wii.
To our Surprise about 75% of games were coming up with a blue screen with the below Error
An error has occurred.
Press the Eject Button, remove the Game Disc, and turn off the power to the console.
Please read the Wii Operations Manual for further instructions."
I origionally thought my HDD had been corrupted and was not impressed. but when i Pluged the HDD back in to my WII it worked fine??
I then thought we must have done something wrong in the Hack, although Dogeggs hack has never failed me before so it had to be something i had done.
The only thing i Personally do my self configure the SD Card (A modified copy of mine with Images etc) So i Formatted the SD Card and started from Scratch.
So Finally the Fix.
Back up your SD Card to your PC
Format the SD Card
Download and install http://usbloader-gui.googlecode.com/..._Installer.exe to your SD Card
Copy the Images folder from your Back Up to your SD Card.
Copy any other Apps or Wads from your Backup to your Newly set up SD card.
Place the SD Card back into your Wii, and select USB Loader.
=No More Error #002!!!!
Please let me know if this doesn't work for you, and i will help where possible.
