hello hoping someone can help -
about 6 month ago i changed the username and password on my cable modem, thought i had saved it - but now i've come to need to access my modem and forgotten what username n passord i used.....
can i get round this
dump the modem via jtag open in an hex editor and search for the word password
If you didn't change the telnet password, it's also possible to log into telnet and view the GUI password there. As seen
here, you can use the following telnet command:
read_memory -s1 -n16384 0x9fd40000
It should spit out something like this, with the username and password in plaintext.
Code:

haxorware's password location is dynamic that will not work everytime
If you forgot the password and you have a jtag, just do this
detect
erase 9FD40000 B0000
Then start over "clean"
