Repacks often force a specific custom IOS (cIOS) that doesn't match your drive's compatibility.
Why this works: Older repacks used d2x v8. Newer drives need d2x v10-beta52 or v11. By switching to 249, you force the loader to use the most compatible base.
| Step | Action | |------|--------| | 1 | USB drive in Port 0 | | 2 | Externally powered or Y-cable HDD (no flash drives) | | 3 | Format FAT32, MBR | | 4 | Install d2x cIOS v11 beta1 in slots 249 (base 56) and 250 (base 57) | | 5 | Delete USB Loader GX config files from repack | | 6 | Set Loader’s IOS to 249, Device IOS to 58 | | 7 | Retry – replug drive if needed |

The loader expects to find a compatible USB storage device formatted correctly (WBFS, FAT32, or NTFS).
If the loader sees a device but cannot talk to it, or sees nothing at all, it throws: Why this works: Older repacks used d2x v8
"USB Device Not Initialized. Switching to channel list mode."
On repacked versions, this message often appears instantly, even with known working drives.
