I UPDATED TO 4.3U AND I DIDNT KNOW IT WOULD MAKE ALL MY GAMES DISAPPEAR fml

[yoongillest]

OK so there I was being a stupid little girl thinking she knows what she's doing.

I really wanted to play the Mario Kart Channel or something but that needed me to connect to WiFi so I tried connecting my age-old Wii, that had already been softmodded beforehand by some guy in some technology store, to the internet. So I thought everything was going well, when the Wii asked for an update and I was like HELL YEAH LET'S UPDATE THIS OLD CRAP it's been too long, like 8 years? So I updated it, and suddenly the Homebrew channel was gone!! I thought it was super weird until I tried opening up the USB Loader GX, AND IT WOULDNT LOAD AND A BLACK SCREEN WITH A BUNCH OF CODES APPEARED that was like this:

"Exception (DSI) Occured!
code code code
STACK DUMP:
code code code
CODE DUMP:
code code code
Reloading in 20 seconds"

And because my parents paid almost 200$ to get the Wii softmodded and installed with like 500 games (that the store bought and \put into this terrabyte so it's kinda legal), I NEED HELP ASAP. OMG THEY STILL DONT KNOW and my mum uses the Gold's Gym game in the USB Loader to exercise ugh why

So I've done research and all of them were like, "You have to softmod it again" and I am seriously the most technologically challenged person ever. I don't know what in the world I'm doing.
So far, I've done the LetterBomb thing (thank Heavens for it), installed BootMii as boot2 and IOS and I got the Homebrew Channel back!!
I thought my work was done but I opened USB Laader and it was still the same.

I'm such a beginner please help. I have a terrabyte full of games that I need to reinstall somehow. And unsuspecting parents that might kill me for wasting their money. My family really loves the USB loader GX man, WE HAD COOKING MAMA

Any next steps??? I've read most of the things at the start of this forum (like the ones in red) but I don't know what I actually have to do next. Please help I'm in such a panic oh my goodness I just wanted to play MarioKart fml
