| Problem | Likely Fix |
| :--- | :--- |
| Router won't enter upgrade mode | Try holding WPS + Power for exactly 20 sec. Some variants use Reset button. |
| Flash tool stuck at 5% | Firewall blocking TFTP. Disable Windows Defender Firewall temporarily. |
| After flash: no internet | Reset to factory defaults via pin hole reset. Then reconfigure APN manually. |
| Telnet says "Access denied" | Flash an "unlocked telnet" bin after main firmware. Some C00 builds block root. |
| Web UI shows half Chinese | Load English WebUI file: webui_en.bin from same firmware pack. |
| Band lock not sticking after reboot | Save AT command as a startup script via rc.local if telnet is available. |
