Arris TG2492 (VM Super hub 3)

[danman]

Something like this:
$ mkdir /tmp/mmc;chmod 777 /tmp/mmc
$ sudo in.tftpd -cls /tmp/mmc
$ ssh root2@192.168.0.1 /bin/bash -i
root2@192.168.0.1's password:
/bin/bash: can't access tty; job control turned off
# cd /dev
# for p in mmc*;do tftp -p -l $p 192.168.0.100;done

I'm getting PMs about how did I extract the FW. It's easy, you need a "better" SD card reader, in my case Transcend TS-RDF5K, SD or microSD breakout board:

and connect corresponding pins on the board:

Then you just insert the breakout board, connect pins to your board and you can extract.

Can i pm you?

Why not ask here?

i have another board, from a 1602A arris . how can i trace or find the corresponding pins ?

Do you have an oscilloscope or a logic analyzer?

no

Can you upload pictures of your board?
