The process of converting a Huawei HG8245H from GPON to EPON is a classic "tech-tinkerer's adventure." It’s often done to repurpose high-quality GPON hardware on networks that use different standards, or vice versa, typically via a dual-mode firmware flash. The Story of the "Hybrid" Router
Instead of risking hardware failure through experimental firmware, consider these industry-standard solutions: firmware huawei hg8245h gpon to epon

Is it worth it?
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. Only for experimentation or if your EPON OLT
If you proceed, look for a file named HG8245H_V300R017C10SPC150_dual_mode.bin (example only). Always verify MD5 checksums from trusted sources.
Network Disruptions: A misconfigured ONT (Optical Network Terminal) attempting to speak the wrong protocol can create continuous light emission (a "rogue ONT"), effectively knocking out internet access for all other neighbors sharing that same OLT split fiber.
This guide assumes your HG8245H is currently running GPON firmware and you have obtained a dual-mode or verified EPON-only firmware.
