Most Huawei HG8245H units are manufactured with hardware specifically optimized for the GPON standard, which supports higher downstream speeds (up to 2.5 Gbps) compared to EPON's 1.25 Gbps. Huawei representatives state that a "forcible switchover" of firmware will lead to unrecoverable faults because the underlying hardware cannot interpret the new instructions.
from GPON to EPON, it helps to examine how these networks operate.

After the firmware flash or mode switch, your work is not done. The ONT must register with the ISP. : Ensure you have the administrator login
A: Reputable technical forums (like TechExams or Netgate) maintain lists of verified Huawei firmware hashes. Cross-reference three sources before flashing.
due to fundamental hardware differences between GPON and EPON standards
To summarize the verified process for :
Huawei does not officially support this conversion. Proceed at your own risk. Always keep a backup ISP-provided ONT nearby.
