6. Post-Upgrade Steps

1. Factory reset (recommended): Press reset button for 10+ seconds or use restore manufactory in Telnet.
2. Reconfigure WAN connections (VLAN ID, PPPoE username/password).
3. Test connectivity: Check internet, Wi-Fi, VoIP, USB storage.
4. Monitor logs for crashes or errors.

E. Obtain the correct firmware.

Warning: Do not use firmware from random forums unless verified by an MD5 checksum. Only official sources:

• Your ISP’s support portal (e.g., Vodafone.de Komfortkiste).
• Huawei Enterprise support (requires a service contract).
• Trusted technician communities (DSLReports, ChinaDevices).

Preparations

1. Identify device model and hardware version
   • Confirm the full model (HG8245Q) and any hardware revision printed on the label.
2. Check current firmware version
   • Log into the web interface (usually http://192.168.100.1 or IP assigned by ISP). Default credentials vary; many ISPs change them. Go to System Information to note the firmware version.
3. Obtain firmware
   • Prefer firmware from your ISP or Huawei support channels. Official firmware is often tied to ISP provisioning and may not be publicly available.
   • If using publicly circulating firmware, ensure it matches model and hardware revision exactly.
4. Tools and access
   • A computer with Ethernet port.
   • Ethernet cable to connect to the ONT (do not upgrade over Wi‑Fi).
   • Administrative access to ONT (web GUI) or SSH/Telnet if provided.
   • TFTP server or FTP client if required by the firmware package/upgrade method.
5. Backup configuration
   • In the web GUI, export or save configuration if the option exists. Copy router settings (VLANs, PPPoE credentials, static IPs, DHCP reservations, Wi‑Fi SSIDs/passwords, port forwarding).
6. Record recovery details
   • Note default credentials, serial number, MAC address, and any ISP-provided activation keys.

Problem 1: “File Error” or “Incompatible Version”

Solution: The firmware is not for your hardware revision. Obtain the correct one. You may need to use a “middle firmware” (an intermediary version) before jumping to the latest. Hg8245q Firmware Upgrade

3. Obtaining the Correct Firmware

Troubleshooting

• Upgrade failed / stuck at boot: Try a power cycle, then attempt TFTP recovery if supported. If device is unresponsive, serial console recovery may be necessary.
• Lost WAN/Internet after upgrade: ISP-specific settings may have been wiped; re-enter PPPoE/VLAN/PPPoE credentials or contact ISP to re-provision the ONT.
• Web GUI inaccessible: Clear browser cache or try different browser. Verify physical LAN connectivity and IP addressing.
• Bricked device: If the ONT shows no signs of life, consult ISP support or a professional technician. Serial recovery can unbrick in some cases.
• Rollback: If the firmware supports rollback, use the GUI or recovery method to restore the previous firmware. If not, obtain the prior official firmware and flash via TFTP/FTP/console.

Post-upgrade checks

• Confirm firmware version in System Information.
• Verify WAN connection and speed tests.
• Check Wi‑Fi SSID/security, LAN DHCP, static mappings, and port forwarding.
• Monitor stability for 24–72 hours.
