serious help needed

I feel i have have just completed fooked my wii up.

Firstly have have been away from the mod seen for a few years now its all changed, i had to dust of the wii again as i decided to give back to nintendo and i pre-ordered zelda skyward sword.

However it arrived a day earlier (today) very excited it asked me to update my wii i thought what the heck my modding days are over and nothing else on wii i want to play it would be shelved afterwards.

The update failed from the disk tried from the internet epic fail, my wii is running 4.0e firmware so i thought its prob the homebrew channel etc blocking the update and i need to reformat my wii to get rid and start a fresh but nope same problem.

Now looking at other threads people running the game via launches but im trying to load my sd card via the home menu and my wii crashes so now i cant access homebrew etc as ive deleted it and cannot run update or access my sd card without it freezing :(

Any help please!

Clearly you have either installed Priiloader and have the block updates hacks enabled or else you installed some StartPatch patches. Try holding reset while turning on your Wii. If Priiloader shows up, go into the settings and disable the update blocking hacks and then you should be able to update from the disc and play like normal.

If Priiloader doesn't show up, it must have been startpatch. In this case, you'll need to run StartPatch again, either via bannerbomb or HBC (which you would have to reinstall via bannerbomb first) and remove the patches using it.
