  • After the later, the modem will install drivers and open the default web browser with the URL address http://modem.home but won't be able to display any content. This is simply because it has no WEB UI
  • Currently, your modem has already been unlocked, and all that is required is flashing the WEB UI. So, install Update_WEBUI_17.100.11.00.03_HILINK 
installing Update_WEBUI_17.100.11.00.03_HILINK

Update_WEBUI_17.100.11.00.03_HILINK installed successfully
Once the WEB UI is installed, the router will now open the web browser showing you the new interface which is the default Huawei UI for all general Huawei modems

Disconnect and insert any sim card and then coonect to the Computer.
