Requirements
- A computer or phone that can use SCP. This guide uses a PC.
- WinSCP for Windows, available here .
- The English language file. You can translate it into Vietnamese if needed, but keep the syntax and leave the filename as base.cn.json.
If the attachment cannot be downloaded, use this Drive link: Download .
Procedure
Enable superuser (root) mode and OpenSSH.
- Open
http://192.168.99.1/newifi/ifiwen_hss.html.192.168.99.1is the default IP of Newifi3 D2 stock firmware; replace it if you changed the router address.

192.168.99.1, port22. - Username: root
