F6005 TIM — F6005 with ZTE branding, like the ones used by TIM

Serial

The ONT has a TTL 3.3v UART console (configured as 115200 8-N-1) that can be accessed from the top surface. To accept TX line commands, the GND of the TTL adapter should be attached to the ONT’s shield:

Note Some USB TTL adapters label TX and RX pins the other way around: try to swap them if the connection doesn’t work.

List of software versions

V6.0.10N14 (TIM)
V6.0.10N20 (TIM)
V6.0.10P2N02 (OpenFiber)
V6.0.10P2N18 (OpenFiber)

Usage

Note The following commands need to be executed on GponCLI via a terminal (serial, telnet or SSH). The models currently distributed in Italy by TIM and OpenFiber have no way to enter GponCLI via serial, only via telnet after flashing a custom firmware.

Unlock serial to flash another firmware

This ONT is the twin brother of CIG G97-CP, if you can find its bootloader (named CIG_bu.en_V3.09.15), you can easly repack the firmware and enable its serial port limited to bootloader. You need a 3.3V SPI programmer (like a modded CH341a) to read and write back the flash.

Note This was tested only on a TIM V6.0.10N20 firmware!

After getting a full dump of your ONT, here is the procedure to replace the original bootloader with CIG’s to enable the serial port:

Cut old bootloader:

dd if=flash_dump.bin of=no_boot_flash_dump.bin bs=1 skip=184064

Attach the new one:

cat CIG_bu.en_V3.09.15 no_boot_flash_dump.bin > mod-boot_flash_dump.bin

Now you can flash the file mod-boot_flash_dump.bin back to your SPI.

After powering up the ONT, the serial port will print this message:

**************************************
*                                    *
*  KEY -- Enter console terminal     *
*                                    *
**************************************

To access full U-Boot a special escape sequence is needed.

If Tera Term is used, create a simple MACRO file that contains this code:

send $1B $1D $0F $0B

Configure Tera Term with the correct serial parameters (refer to Serial paragraph), select the created MACRO file BEFORE powering up the ONT but DON’T OPEN IT NOW, power-up the ONT and when you see the above message, quickly open the macro to reach the U-Boot prompt:

9601D#

Note Note that this proceedure needs to be done each time you power-cycle the ONT

Now with the U-Boot prompt a custom firmware that enables TELNET can be flashed. Please note that if a TIM or OpenFiber base firmware is used, the TTL will be silent after kernel loading because it is disabled at kernel level.

Here is the procedure to flash a custom firmware on the ONT via the U-Boot console:

Attach the ONT via ethernet cable to your PC and configure it to have IP 192.168.1.2
Launch TFTP server and place custom firmware inside its root folder renamed into cramfs.img.crc. Be sure that the file has this name, otherwise the upgrade procedure will stop immediately
Run this command on U-Boot prompt:

9601D# upgdimage
start : 0x00200000 size :0x00700000
Using LUNA GMAC  device
TFTP from server 192.168.1.2; our IP address is 192.168.1.1

Note Please note that some OLTs (like TIM’s Alcatel OLTs in Italy) need to have software image 0 or 1 set as active. So in this case, these commands will have to be executed twice to flash the image on both slots:

ImageA:

set activeimage imagea
saveenv

And flash image with the upgdimage.

ImageB:

set activeimage imageb
saveenv

And flash image with the upgdimage.

This way both slots will have the same firmware version and will avoid any swap by the OLT.

After these steps, power-cycle ONT and login via Telnet with root\admin credentials. From this moment you can simply spoof your ONT with the usual commands.

Known Bugs

The buffer size of the hardware is suboptimal: because of this the ONT is unable to work at full speed during uploads if the server is geographically and/or latency-wise far. There are no known problems if there is only one subscriber on the GPON tree. In versions V6.0.10N14 and V6.0.10P2N02 this problem is felt more than with newer firmware as in the new versions (V6.0.10N20, V6.0.10P2N18, V6.0.10P2N19), an attempt is made to avoid buffer filling by means of pause frames. Not all routers support pause frames and some may still suffer from problems with the latest updates.

In version V6.0.10P2N18, problems were found in download speeds with 1 Gbps links.
