Huawei Enterprise markets the HG8245H to ISPs and large corporations. These entities do not want their field technicians bricking thousands of units by loading random internet firmware. They also do not want firmware downgrades that reactivate debug interfaces or exploit vulnerabilities (like the famous backdoor vulnerability in R013 firmware).
I am writing to report a persistent issue regarding a firmware upgrade for the Huawei HG8245H
Even if you manage to bypass the signature check (which is incredibly difficult and risky), you face the issue of ISP customization.
If U-Boot itself is corrupt, you can desolder the SPI flash (25Q128 or similar) and program it externally with a CH341A programmer – but this voids all warranties and requires advanced soldering.
Many HG8245H units allow firmware upload via a raw POST request, bypassing the GUI file validation.
Most HG8245H units are provided by ISPs (Internet Service Providers). These units often run customized firmware that prevents manual local upgrades to protect the carrier's network configuration.
Some firmware versions (e.g., V300R013C10SPC118) have weaker signature checks.
