For dual-mode hardware variants, Huawei utilizes firmware to lock or unlock the operating mode based on ISP requirements. Flashing a customized, unlocked, or regional firmware allows the user to switch the software stack from GPON to EPON. Prerequisites and Risks

After analyzing countless forum threads (DSLReports, 4PDA, Huawei-Hack), the consensus is clear: While the optical hardware can often support both, the bootloader, driver, and management layers are deeply entangled.

Find a bootloader from a known dual-mode device (e.g., HG8245H with hardware version 4B4.A that supports both). Extract the uboot partition: firmware huawei hg8245h gpon to epon

However, certain iterations of the HG8245H utilize a dual-mode chip (often called "XPON"). If your specific hardware revision contains an XPON-capable chipset, a firmware modification or configuration change can successfully toggle the device into EPON mode. Prerequisites and Preparation

If not already enabled:

If it were possible (custom firmware + hardware mod), the changes required are:

Only for experimentation or if your EPON OLT is known to accept GPON ONTs in EPON mode (rare). Most EPON networks use OAM (IEEE 1904) not OMCI, so management may fail.

In some cases, a direct command change may fail, especially on certain firmware versions. If you receive an error saying "Command is not existed," an alternative approach is to upgrade to a compatible firmware version first.

: EPON OLTs authenticate devices based on MAC addresses, while GPON uses LOID/SN. Ensure your destination OLT is configured to register the converted device's MAC address profile.

Firmware Huawei HG8245H GPON to EPON: Comprehensive Guide and Tutorial Prerequisites and Risks : Instead of purchasing entirely

Converting a Huawei HG8245H from GPON to EPON via firmware is a high-risk, high-reward endeavor. Successful conversions are possible only on specific hardware revisions (V3/V5) using dual-mode bootloaders or custom-built firmware from trusted developer communities. For most users, the safest path is to purchase an official EPON ONT or request a replacement from your ISP.

Not all HG8245H units are created equal. To convert GPON to EPON, your device must have a (e.g., HPSF2120, RTXM169-502, or similar). Many Chinese-market HG8245H units come with GPON-only modules.

An Ethernet cable connecting the PC to LAN Port 1 of the ONT.

Flashing new firmware typically erases Internet Service Provider (ISP) configurations, including authentication credentials and VLAN settings required to access the network.

Open the file in a text editor and search for the tag containing network modes (e.g., OltMode or UpstreamMode ).
