Try this script , i mashed it from another one but it should work for the 1MB spi chip on board that device.

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...
