Cause: You uploaded a zipped file ( .zip or .rar ) or a file meant for a different router model.

Huawei classifies the HG8245Q as an enterprise carrier device. Finding the exact software requires precision. Turn your router upside down and locate the product label.

If your internet configuration is wiped out post-upgrade, navigate back to > Configuration File , click Upload Configuration File , select the backup file you created in Step 2, and reboot the device. To help narrow down your next steps, please let me know: Who is your Internet Service Provider (ISP) ?

Note down the exact model number, hardware version, and your current software version.

Always use a wired Ethernet cable. Do not upgrade over Wi-Fi, as a signal drop can brick the device.

Older firmware versions often contain unpatched vulnerabilities that leave your local network exposed to external exploits, credential theft, and unauthorized access. Upgrading ensures your firewall and encryption protocols (like WPA2/WPA3 stability) are up to date. 2. Improved Wi-Fi and Routing Stability

If you want, I can:

This is common. You must re-enter VLAN IDs, PPPoE credentials, and VoIP settings. If you didn’t back them up, contact your ISP for their “ONT provisioning” guide.

ISPs can push firmware via OMCI. Do not attempt to simulate this.

Cause: The firmware wiped the ISP's VLAN configuration or PPPoE credentials.

Which method is available depends on device firmware and ISP locking.
