Sometimes the update doesn’t start or freezes. Here’s how to fix common errors:
| Problem | Likely Cause | Solution |
| :--- | :--- | :--- |
| TV ignores USB drive | Wrong file name or file system | Reformat to FAT32. Rename file to install.img or as per your model’s manual. |
| “Invalid Update Package” | Wrong firmware for your model | Double-check the model number. Even one letter difference (e.g., X32G900 vs X32G901) matters. |
| Update starts but stops at 50% | Corrupt download or bad USB sector | Re-download the firmware. Try a different USB drive (older, smaller capacity drives work best). |
| TV turns on but screen is black | Incorrect “USB Top” port used | Move the USB to a different port. The “Top” port is usually the one farthest from the HDMI jacks. |
| Remote doesn’t work during update | Normal behavior | Do not use the remote during the flashing process. Only use physical TV buttons for power. |

The USB Top method bypasses the internet entirely. It is the "Gold Standard" for service technicians because it performs a clean flash rather than an incremental patch.
