Instead of forcing a conversion on a GPON-only unit, many modern Huawei models are sold as (dual-mode) devices. These units are designed to automatically detect and adapt to whether they are connected to a GPON or EPON network, eliminating the need for risky firmware "exclusive" hacks.

EPON, on the other hand, is a point-to-point network technology that uses a separate optical fiber for each user. It offers high-speed data transmission rates of up to 1 Gbps downstream and upstream.
The exclusive HG8245H5 GPON-to-EPON conversion of 2021 stands as a testament to the hacker ethos: that hardware is defined not by its label but by the firmware that animates it. Technically, the feat was real—exploiting dual-mode PHYs and bootloader tricks. Practically, it was a compromise, producing an ONT that was neither a stable GPON device nor a fully compliant EPON terminal. By late 2022, Huawei patched the UART vulnerabilities and introduced hardware fuses that permanently locked the PON mode after first boot. The 2021 method became obsolete, a fossil in the rapid evolution of FTTH. Yet for a brief window, a handful of engineers proved that with a soldering iron, a serial cable, and reckless determination, the laser in a Huawei GPON box could sing the Ethernet song—even if slightly out of tune.
Specifically, converting the Huawei HG8245H5—a ubiquitous GPON terminal—to function on an EPON network.
