To troubleshot anything, you swap element to narrow the problem.
it works with USBLoaderGX, it works with everything !
Try a different HDD to see if the problem is hardware or software
try a different wiimote, a different IOS slot, a different loader (wiiflow, cfg), a different way to launch homebrew (channels, hbc, etc.), a different sd card, a different game,
etc.
Rev.1262, IOS250 (Rev 65535) +AHB (d2x v10beta52 base57). The console is connected by wi-fi, and the loader doesn't find new updates, so my guess is that I'm in the latest version.
- your IOS is good
- your version is not really the latest. it's the "latest internally released", but the latest stable is 1268, latest beta is 1268mod4, you have to replace the boot.dol manually if you want to update. Links are in my signature.
Black screen is usually, in logical/common occurrence order:
- bad video mode (reset settings should have fix it)
- wrong USB Port !
- Flashdrive instead of HDD
- loader IOS and game IOS are different, gameIOS not using a good slot. (reset should have fix it)
- HDD does not have enough power (y-cable, external power, try a different usb cable, yes different cable sometime fixed problematic hdd!)
- ISO is bad
- ISO path is wrong, fix
this way
- your HDD is FAT32, your files are write protected.
- You enabled debug pause, and don't have a debugger (reset setting should have fix it)
There might be other possibilities, I don't think of them right now
