A factory reset router will also be sent an updated firmware if there is one available.
==Reset to the ZyXEL Factory Settings==
To erase the default AAISP settings, the 'ROM-D' file needs to be cleared, this is done via the CLI (Telnet or SSH) using the supervisor user and then issuing the <syntaxhighlight inline enclose="none" lang="bash">save_default clean</syntaxhighlight> command.
Here is an example:
In this state, the router has ZyXEL's default IP address, username and password.
=Adding the AAISP rom-d file=

If you need to restore an AAISP rom-d file, then here are the steps to take. Support are able to provide you with the rom-d file on request.
FTP is used to add the rom-d file. Here the AAISP provided rom-d file is actually called vmg1312-b.rom-d, so when we upload it we have to specify the target file name of rom-d. (the lines highlighted contain things you need to type in)
