Manually flashing new firmware to Sagem Fast 3464 (bbox2)


Yesterday I got a Sagem Fast 3464 modem that was in safe mode. It said “your cpe is now in rescue mode”. My mission was to have it download the latest firmware.

Normally the modem will download the latest firmware by itself when connected. But this one didn’t.

Another way to get it to update was to somehow provide it with a TFTP server with the correct files hosted. That implied listening to the modem with a packet sniffer and watch for it to try and make a connection to a pre-defined TFTP server. Like explained here:
But that didn’t work either, since the modem did not initiate any kind of traffic other than some IGMP packets. I guess these instructions only apply when a firmware was already present, and since this modem was in CPE rescue, it did not work as expected.

Important: If your modem is NOT in recue mode and it shows anything else than “your cpe is now in rescue mode” in your browser, then you need to flash the rescue mode firmware first. In that case, don’t continue, but instead follow the instructions here :…

I managed to connect using telnet (PUTTY) using the standard username/password. As it was an old modem, I used login:admin password:OLOVDSL2 ( Which is the non-belgacom password. If that doesn’t work for you try login:admin password:BGCVDSL2 )

This made it possible to instruct the modem to download the new firmware. But first we need a TFTP server that is hosting the firmware files. You can find one here.
I found a working firmware (60A06W Belgacom) here: direct link (source:… )
I configured the TFTP server to host the firmware (the setup is very basic).

These are the instructions I to use in the telnet session:

login: admin
Password: ********
[admin @ home]$ load -u tftp:// -s 6

Loading image, size is 7602176 bytes
Download completed successfully

Returned 0
[admin @ home]$ reboot

Change the IP adress to the one your TFTP server is running.

That’s it. Let it download and when finished reboot.
The modem should now have runtime code 6LR10A-60A06W.
Configure it by using a web-browser, and the serial number as a password.
Then let it sit for a while to complete the latest update by itself.

Hope this works for you.
