Some blog posts suggest a method to bypass the UI lock using the "SU" (Super User) shell. This is high-risk and strictly for advanced users.
Enable Telnet on your HG8245h (if disabled, use the hidden web page):
Use a Telnet client (PuTTY):
Host: 192.168.100.1
Port: 23
Login: root
Password: admin (or Hw8@cMcc, or your ISP’s admin password)
After the device reboots, perform the following verification steps: Huawei Hg8245h Firmware Upgrade
After reboot, verify:
| Check | Command / Action |
|-------|------------------|
| Firmware version | Web UI or display version |
| ONT registration status | Status → GPON Status → O5 (Operation state) |
| LAN connectivity | Ping 192.168.100.1 |
| Internet access | Test public IP and DNS resolution |
| Wi-Fi (if enabled) | Connect from client device |
Rollback plan: If issues arise, reload the previous firmware using the same method.
