  3. Write down the following information:
    1. Número de Série GPON (a.k.a. GPON Serial Number)
    2. SLID (a.k.a. PLOAM)
    3. Endereço MAC da LAN (a.k.a. GPON MAC Address)

GPON ONU Stick details

  • PLOAM Password: GPON Serial Number (ex. INVP1234567890)

  • OMCI Hardware Version: RTF3505VW-N1

  • OMCI Software/Image Version 1: R3505VWN1001

Flashing the GPON ONU Stick

Reference Hack GPON Page

If available, serial UART access to the ONU stick is recommended in case of any failures (ex. flashing failure).

  1. Download the "6BA1896SPLQA42_MODDED_ver5-1.img" image
  2. Copy the image to /tmp on the ONU stick
    1. One method is using SCP, but modern clients may have compatibility issues with the SSH encryption used by the ONU Stick
    1. I used a Mikrotik RouterOS router as a middleman to copy files with SCP between the stick and my MacBook
  3. Flash the image using the following comands
    1. mtd -e image1 write <image relative file path> image1
    2. fw_setenv committed_image 1
    3. fw_setenv image1_is_valid 1
    4. reboot
  4. After the reboot, telnet to "192.168.1.10" (no login required) and run the command "firstboot".
    1. You will see the serial output in the image below after it is finished.
  5. Reboot the ONU with "reboot". You may need to reset your SFP interface to gain access to the stick again after this reboot
  6. The ONU stick management will now be reachable at 192.168.1.10 over SSH using the login root:root
Completed output of the "firstboot" command
