So... they say hindsight is 20/20. And I've proved that point... So with all these things we're Never, ever supposed to do. Is there a fix if we stupidly did?
I was installing USB Config as a channel when I was informed my Wii was out of memory and had to go to Data Management to fix the problem. Now, there was nothing that I wanted to remove from there except for the WiiFlow forwarder channel, which was taking up a lot of space, and would be redundant if I wanted to use USB Config instead.
So I boot up into Priiloader, launch HBC and Wad Manager to remove the WADS that I had installed when installing WiiFlow and the WiiFlow Forwarder (I should claim mea culpa here as when I installed WiiFlow, I was just following a guide a had DLed and just blindly followed it). I hate to say it, but without thinking I removed a file named "Wiiflow Starnight Channel Forwarder-WSNF" as well as "4.3U_SystemMenu_v513DarkWiiRed.wad"
Now let me explain, I didn't think removing the "4.3U_SystemMenu_v513DarkWiiRed.wad" would cause a problem, because when I installed that in the first place it caused me problems and I used DOP-Mii:Wii Brew Edition to downgrade back to 4.2, which I had been at before I installed this .wad (yes, I found out later downgrading was bad) and I assumed that I'd be running on a 4.2 system menu again.
After removing these wads my Wiimote wouldn't work and I was left with no option but to restart, and of course now I can't start my Wii. I can't load Priiloader anymore in order to boot BootMii. It's not even getting me to a bricked screen, it seems as if its not even recognizing the Wii anymore - as my TV is just displaying a "No Usable Signal" on screen which is what it displays on the input channel before a device (ie. DVD player, console etc...) is powered up.
As I type this I'm in the process of copying over the backup I had made of my nand/keys file from my Mac in a desperate hope that this fixes it, but if it doesn't, is there anything I can do? **EDIT** This had absolutely no effect on anything and I still can't launch my Wii.
