I finally managed to get my hands on a Huawei HG8245H and successfully cross-flashed it from GPON to EPON mode. There is a lot of conflicting info out there about the 8245 series supporting EPON, but I can confirm this specific model is hardware-capable if you have the right firmware. Go to WAN > EPON Settings (If this
A firmware means that dozens of users have tested the specific .bin file on a physical HG8245H, confirming that the web interface changes to “EPON mode,” the PON LED behaves correctly, and the device registers with an EPON OLT (e.g., ZTE, Huawei MA5600T in EPON mode).
