A standard Ethernet cable (Cat5e or Cat6) connecting the LAN1 port of the HG8245H directly to your computer's Ethernet port. Disconnect all fiber optic cables during the flashing process.
The Huawei HG8245H contains a system-on-chip (SoC) that natively supports the underlying framing structures of both GPON and EPON protocols.
The answer is yes —but only if you have the correct, firmware that converts the GPON hardware logic to EPON mode. This article provides a deep dive into finding, verifying, and flashing the firmware for Huawei HG8245H GPON to EPON verified builds. firmware huawei hg8245h gpon to epon verified
Open PuTTY, select , enter 192.168.100.1 , and connect.
The "OMCI Status" or "GPON Mode" labels should change to or OAM Status . A standard Ethernet cable (Cat5e or Cat6) connecting
: If the ONT shows "O5" status or fails to register on the EPON network, the OLT software may be strictly blocking third-party non-EPON native hardware profiles.
Never skip this step. Export your current config.xml . If the EPON firmware fails or doesn't recognize your fiber signal, you will need this backup to restore the device to its original GPON state. 3. Uploading the Verified Firmware The answer is yes —but only if you

Once the firmware is successfully written to the flash memory, you must configure the device mode: Switching Modes via CLI Open your terminal (PuTTY) and Telnet into 192.168.100.1 . Log in with your root credentials.
Flashing firmware at the bootloader level carries inherent risks. Modifying your ONT firmware may void your device warranty and, if performed incorrectly, can permanently brick the hardware.
By default, Telnet is disabled. You need to enable it via the web interface (often using hidden URLs) or using the ONT维修使能工具 (V300R13C10SPC800).
