Converting a from its native GPON mode to EPON (effectively making it an XPON or dual-mode device) is a common requirement for using the device on different optical line terminals (OLTs). While Huawei officially states that hardware differences between GPON and EPON prevent such conversions, community-verified firmware and flashing tools have made this possible for many users. ⚠️ Critical Warnings

While these two standards are generally incompatible at the hardware level, certain allow the HG8245H to function in dual-mode or switch its protocol entirely. This article explores the technicalities, risks, and step-by-step process of performing a verified GPON to EPON conversion.

This is riskier. It replaces the Uboot environment variables to force EPON detection. Only use if Option A fails. While these two standards are generally incompatible at
