ZTE/MTN MF831 firmware hack to get Port Forward and DMZ settings

0. Download and install adb (Android Debug Bridge) and if you have a Mac, install the Horndis tethering driver for MacOS
1. Plug your stick to your Mac/PC and enter the following url in your browser: 192.168.0.1/goform/goform_set_cmd_process?goformId=USB_MODE_SWITCH&usb_mode=6 You will get: {"result":"success"}
2. Open the Terminal/Cmd and test the connection with adb shell. If you get the shell, type exit…
3. Download the menu.js from the stick: adb pull /usr/zte_web/web/js/config/datacard/mf831/menu.js
4. Make a backup copy from menu.js.
5. Edit the menu.js and add the following objects after the "#pin_management":

{
hash:'#port_forward',
path:'firewall/port_forward',
level:'3',
parent:'#device_setting',
requireLogin:false,
checkSIMStatus:false
},

checkSIMStatus:false
},
{
