how to dump firmware from broadcom based modems
#3
I´m really trying to get the nonvol (I even PMed you about that!) but I'm having trouble locating it

I dumped manually, thru diag readmem, the the regions of Permanent NonVol and all the 3 Dynamic ones but got no luck with cmnonvolextractor, just errors

I must be doing something wrong, how can I locate the 2mb CFG inside the flash? what the offset would be?

and how much memory there is inside the modem? because it´s possible to read portions that go beyond the 8mb region
If I manage to dump the full 8mb, how could I extract the certs, since cmnonvol only works with the 2mb cfg?

damn I think I´m so close but I lack the knowledge!
