Manufacturers implement a "SIM Lock" or "Network Lock" at the firmware level. This is a database of allowed MCC (Mobile Country Codes) and MNC (Mobile Network Codes).

If your current provider firmware retains the native software update option, use this path:
| Problem | Possible Cause | Solution | |---------|----------------|----------| | "Firmware upgrade failed" | Wrong hardware revision | Check if your router is S25 or S25G. Download the correct file. | | Router reboots but SIM still locked | Unlock didn't persist | Perform a factory reset via the web interface, then re-apply the .bin . | | No band lock menu after unlock | Used basic unlock version | Find and flash Unlock-zlt-s25-v2.bin or later. | | Router stuck on boot loop (blinking LEDs) | Bricked device | Try a : Hold reset button for 30 seconds while powering on. If that fails, you need a UART serial cable and stock firmware to revive it. | | Cannot access web interface | IP changed | Default IP is 192.168.1.1 . Try 192.168.0.1 or check your PC's gateway via ipconfig (Windows) or route -n (Linux). |
