why CmNonVol Extractor won't work on the 32kb nonvol? - jofre - 24-07-2017
Hi all, it's been a while
I doing some experiments with CmNonVol extractor, so I downloaded the 32kb NonVol from Haxorware and tried to extract the certs with cmnonvol but nothing happens
also, I'm trying to dump the nonvol from another modem via telnet but I´m having a very hard time
the Flash Device Information show the addresses of the permanent and dynamic nonvol, tho they all are 64kb instead of 32.
Is it possible to read the full 2mb from the flash?
the full flash has 8mb, how could I find the 2mb that corresponds to the config?
