Please help me. I've tried almost everything suggested in the forums to try and get the letterbomb hack to work. Nothing works.

I have a SanDisk 2GB SD card endorsed by Nintendo for the Wii. I've tried several other microsd/adapter cards 1GB and 2GB variations.
I have tried, formatting the wii.
Inserting the SD before AND after bootup
Scrolling through dates
Changing the date
Changing the date and time
Formatted all sd cards to both FAT and FAT32

Nothing works

Initially I was on 4.2E softmod, but it got updated to 4.3E stock. The wii is around 3-4 years old.

Please help
