Try this script , i mashed it from another one but it should work for the 1MB spi chip on board that device.
You will not be able to read from the NAND chip though.

Tanks for the script it seems to work, i dont think i can't do anything else with this modem, if i change anything in the config file my CM-mac en Serial number disappears so it gets useless to me, i need to find a way into the NAND, or a difrent modem :p, The ting i want to do is put in my own cm mac and serial number of a 0 euro contract of my company, because i would like to carey a test modem with me while working to diagnose docsis problems, BTW if i copy this flash chip of a other modem (got like 20 laying around) it clones it... but if i edit that file it removes the mac and sn

It wont be that simple to change mac and serial as there would be a checksum involved somewhere hence corrupting the image. If you had full shell access to this device then it may be possible.

I did enable shell access but i only got a limited CM>| prompt, and i can't find the password for the linux script...
