There may be many reasons why the Kirin terminal cannot be opened. Reinstalling the system will not solve the problem. The investigation can be conducted according to the following steps.

1. Check whether there is any related hardware failure. For example, check whether the battery of Kirin terminal is used up or insufficient, and whether the screen is damaged. If it is a hardware failure, you need to contact the manufacturer for repair or replacement.

2. Check whether there are other problems in the operating system of the terminal. For example, whether the operating system is outdated, whether a large number of useless files are stored, etc. You can try networking, update terminal firmware and drivers, and clean up terminal storage space.

3. Check whether there is a problem with the application. For example, whether there are many loopholes, whether it needs to be updated, and whether it is compatible with the terminal system. You can try restarting the terminal or uninstalling the application, and then download the installation again.

4. Try to test the Kirin terminal application with other terminal devices. If other devices can't open the application, the software version may not support it or there is a big bug. You need to contact the manufacturer or developer of the application for technical support.
