Most stock Huawei firmwares restrict Telnet access by default. You may need to enable it:

Because a GPON firmware GUI will reject an EPON firmware file as "incompatible," you must bypass the operating system check using the Huawei Multicast Upgrade Tool.

I plugged the unit into my ISP’s EPON OLT.

Original EPON hardware cannot be converted to GPON due to fundamental optical module differences. However, GPON hardware can typically be converted to EPON or configured for dual-mode operation. Older HG8245H units are particularly sensitive to parameter modifications, making verified firmware essential for successful conversion.

Mode parameter combinations:

Newer original firmware patches disable Telnet by default for security. You must use an older V300R013 or V300R015 intermediate firmware to open Telnet privileges before migrating to your final EPON configuration file. Bridging the Gap: Converting Huawei HG8245H from GPON

Browse and select your verified EPON/Dual-Mode .bin firmware file. Click .

Once the device reboots with the new firmware, you must explicitly instruct the software to run in EPON mode.

Change the mode to EPON by executing: set optical mode epon Use code with caution.

Searching online forums (DSLReports, 4PDA, Huaweifirmware) yields hundreds of bricked HG8245H units. Why? Because people flash random firmware without verifying the board ID or the target standard.
