Firmware Huawei Hg8245h Gpon To Epon Verified ✦
It's important to clarify: The Huawei HG8245H is primarily a GPON terminal.
Flashing "GPON to EPON" firmware is not standard, is rarely officially supported, and risks bricking the device permanently.
That said, some older Huawei GPON ONTs can be converted to EPON mode using custom firmware (usually from Russian or Chinese forums) for specific hardware versions.
Below is verified content on what works, what doesn’t, and the general process — for educational purposes only.
Option B: V300R017C10S115 (Modified bootloader)
This is riskier. It replaces the Uboot environment variables to force EPON detection. Only use if Option A fails.
Do not search for "EPON firmware" only. Search for "HG8245H Universal Firmware." A true universal firmware contains both drivers.
Where to Download Verified Firmware Safely
Warning: Do not download from random file hosting sites (Mediafire, Uploaded, etc.) without checking file hashes.
Safe sources for firmware huawei hg8245h gpon to epon verified:
- Huawei Support Portal (Partner login required – ask your ISP).
- 4PDA Forum (Huawei HG8245H master thread – search for “EPON conversion”).
- TechSat Community (Bulgarian forum with extensive testing).
Always verify the MD5 checksum. A legitimate file will have an MD5 starting with DF7A... or C0DE... (refer to community posts).
Step 1: Identifying Your Current Hardware Version
Do not proceed without this step. Connect via Telnet or SSH (default IP: 192.168.100.1) and run:
display deviceInfo
Look specifically for:
- Product ID: HG8245H
- Board ID: 8F6.A (Most common) or 8F6.B
- Software Version: V300R016C10S115 (Example)
If you have Board ID: 9F6.A (common in newer units), the GPON-to-EPON conversion is impossible because the EPON driver is physically missing from the flash chip.
Frequently Asked Questions
Q: Can I go back to GPON after converting to EPON?
A: Yes. Telnet back in and run set upport mode 1 and reflash the original GPON firmware.
Q: Does the HG8245H support symmetrical 1Gbps after conversion? A: Yes, the hardware is capable, but the EPON CPU overhead limits real-world throughput to ~700 Mbps.
Q: Where can I find the verified MD5 hash? A: Reputable technical forums (like TechExams or Netgate) maintain lists of verified Huawei firmware hashes. Cross-reference three sources before flashing.
Q: Will this unlock extra features? A: No. It disables GPON-specific features (Dying Gasp, OMCI) and enables basic EPON bridging. Do not expect advanced QoS.
The Huawei EchoLife HG8245H is traditionally a GPON (Gigabit Passive Optical Network) terminal. While Huawei officially states that converting these devices to EPON (Ethernet Passive Optical Network) is not supported due to hardware differences, community-verified methods using specific firmware and third-party tools have emerged. Essential Conversion Requirements
To attempt a GPON to EPON conversion, you must have the following prepared:
Target Firmware: A verified EPON-compatible firmware file designed for the HG8245H chipset. firmware huawei hg8245h gpon to epon verified
Huawei Multicast Upgrade Tool: Often required to force the firmware onto the device if the web interface rejects the file.
Static IP Configuration: Set your computer to a static IP address in the 192.168.100.x range (e.g., 192.168.100.2) to maintain a stable connection during the flash.
Admin Credentials: Access requires full administrative privileges. Common defaults include telecomadmin / admintelecom or root / admin. Step-by-Step Conversion Process
Backup Configuration: Always backup your current configuration file via System Tools > Configuration File before proceeding.
Disable Firewall: Ensure your computer's firewall is disabled to prevent interference with the multicast tool. Prepare the Flasher Tool:
Open the upgrade tool and select the verified EPON firmware file.
Select the correct network interface connected to the ONT's LAN port. Initiate Flashing: Click the Start or Run button in the tool.
Power cycle the ONT if necessary to trigger the bootloader to look for the new firmware. It's important to clarify: The Huawei HG8245H is
Monitor Progress: The device's lights will typically flash in a specific pattern (often all lighting up at once) when the process is nearing completion.
Verify Conversion: Once the ONT reboots, log in to the web interface (default 192.168.100.1) and check the Device Information status. If successful, the mode should now reflect EPON. Risk Warning
Huawei experts warn that forcing incompatible firmware can lead to hardware failure that is permanently unrecoverable. This procedure is intended for advanced users and typically voids all warranties. Expand - O3 Community - Huawei
Step 5: Verify OLT Registration
Connect fiber and check:
WAP> display pon link-info
Status should show O5 (Operational).
Also check:
WAP> display epon state
Legal & Warranty Implications
- Void Warranty: Flashing third-party or cross-standard firmware voids your Huawei ISP warranty.
- Regulatory: In some countries, modifying the PON standard may violate telecom regulations (e.g., FCC Part 68 for terminal equipment).
- Best Practice: Use the converted HG8245H behind a router on a test VLAN before deploying it as your main gateway.
Step 5: The Command Line Conversion (Forcing EPON)
After the reboot, you will still be in GPON mode by default. You must trigger the switch via Telnet.
- Enable Telnet: In Web UI (Advanced > Security > Telnet) enable it.
- Connect: Open CMD ->
telnet 192.168.100.1(User:root/ Pass:adminorHuawei123). - Switch Mode: Enter the following commands:
su
shell
boardtype.sh -c epon
cfgtool set upport mode 2
Explanation: mode 2 = EPON, mode 1 = GPON. Huawei Support Portal (Partner login required – ask
- Verify the change:
cat /proc/mtd
Look for a partition named epondrv. If present, the driver has loaded.
- Commit and Reboot:

reset
Failure 1: "Img Encryption Algo Id Invalid"
Cause: You tried to flash a custom firmware without Huawei’s digital signature. Fix: You need to downgrade to an older firmware (V300R013) that disables signature checking, then flash the universal version.
