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.

Unlike GPON, which relies heavily on SN (Serial Number) or Password (LOID) authentication, EPON systems authenticate devices primarily through the WAN MAC address. Navigate to the ONT web interface.
