The US version of BlackBerry priv can't be used normally after returning to the factory.

What you want to ask is the reason why the US version of BlackBerry priv can't be used normally after returning to the factory? The reason is that the device reset is incorrect and there is something wrong with the software.

1. Follow the correct steps to restore the factory settings. Find this option in the Settings or System menu. Make sure all data and settings are cleared.

2. After the factory settings are restored, you need to reinstall the application and update the operating system. The inability to receive basic functions such as short messages and telephone calls is caused by software problems.
