Do you have a twilight hack saved in the wii system memory? Do you at least have a patched wii menu with rescue system, via starfall v0.5?
Do you have an autoboot copy (or at least a normal copy) of Zelda TP?
How did you brick your wii? What system version is it?
Those are all questions that need to be answered if you want to fix your wii without savemii/modchip. But still, if you missed the first two questions, chances are you will need to get savemii or/and a modchip to save your Wii.
