Firmware Huawei Hg8245h Gpon To Epon May 2026

After reboot, the ONT should identify as EPON.

To attempt this conversion, you will need: firmware huawei hg8245h gpon to epon

WAP> get upport mode
Current mode: EPON (2)

Fiber optic forums often have swap groups. Trade your GPON device for someone’s EPON unit. After reboot, the ONT should identify as EPON

You need a custom firmware that unlocks the set upport mode command. The stock Huawei V300R013 and later typically block this. Fiber optic forums often have swap groups

Look for firmware with R016 or R017 in the name that has been “unlocked” (e.g., from community sources like 4PDA or Huawei-Firmware.com). I used: HG8245H_V300R016C10SPC150_UBoot_UNLOCKED.bin

Even with dual-mode uboot, the optical module’s EEPROM often contains a vendor ID and mode flag. Use i2cget and i2cset commands in Linux shell (after boot):

# Read current mode
i2cget -y 0 0x50 0x7A
# Write EPON mode (example value – research required!)
i2cset -y 0 0x50 0x7A 0x01

Warning: Incorrect I2C commands can permanently disable the optical module.
