Denon X4000 Factory Reset
1.0 Save Settings
1.1. Using IE to perform a SAVE of the config.dat file may or may not work, however using another browser
will generally work every time. Turn ON the receiver but select a non-network input. Enter the following URL
into your laptop/desktop web browser replacing the 192.168.1.xxx with your own unit's IP address. The URL is
case-sensitive.
1.2. <192.168.1.xxx/SETUP/OTHERS/SAVE/f_config_save.asp>
1.3. This dialog should be displayed on the laptop:
1.4. If you are having difficulty SAVE(ing) a file, make sure to stop any network playback by first playing
something on the network and then either pressing the Stop Playback (black square) or the ENTER button on
the remote for a few seconds. You may also need to set "Network Standby" to OFF (contrary to what the
Owner's manual indicates). Perform a “soft reset” (unplug power for 5 minutes) after SAVE.
1.5. The config.dat file should be about 348kB for old models, 952kB for newer ones; however, it's a good idea
to confirm the AVR is actually saving data in the file as the file size will be 348kB or 952kB whether it's all
zeroes or filled with zeroes and some data. If it is all zeroes, it will not LOAD successfully. Use a Windows or
Mac hex viewer to view the file and confirm whether it is all zeroes or not. (Tip: some word processors will also
display the HEX codes if you rename a copy of the file to “config.txt.”) If you do get a file with all zeroes or if a
file with data won't load properly, then perform a soft reset, set Network Standby to OFF/Off in Standby, cycle
the AVR OFF/ON and then try a SAVE again which should result in a config.dat file with non-zero data.
1.6. It's also a good idea to SAVE the settings prior to a firmware update even though firmware updates
generally don't change the system settings. If you are having difficulty using IE, try using Firefox or Chrome
(see Post #2775 of the 2013 Denon AVR thread). If still no joy when trying to LOAD the config.dat file, try
setting IP Control to "Off in Standby", cycle the AVR to OFF, then ON again and try the LOAD. If yet still no
joy, try resetting the microprocessor and then do the LOAD again.
