| Symptom | Solution | |---------|----------| | No screen change, box boots normally | Rename file to auto_update.bin and retry | | Progress bar stuck at 99% | Wait 10 minutes; if no change, power cycle (risk) | | “USB Error” | Try a different USB (older, slower 2.0 drives work best) | | Box now has a green screen | Wrong firmware – you need a recovery via serial cable |

Copy the .bin file to the root directory of your USB drive (don't put it in a folder).
