Point Mobile released a new FOTA application for improved security.
Previous FOTA is no longer available. So to perform OS update via FOTA, please download the new FOTA application from Point Mobile Service Portal and install it on your device.
The new FOTA application is pre-installed on the OS version in the table below. The device with those OS versions doesn't need to install the new FOTA application. ( You can check the OS version of your device in Settings > About phone or System > Build number )

Go to FileExplorer and install the APK file.
You may allow the Unknown sources setting value for installing the file. After installing the new FOTA application, DISABLE the Unknown sources option for preventing security issues.
