1, charge it with a wire for a while and try to turn it on.
2. Take out the SIM card and SD card at the same time, and then press the power-on key 10 seconds or more to test whether it can be turned on.
3. If you can enter the boot interface, but the phone can't enter the home page, please restart the phone and try. The operation steps are as follows: press and hold the power button and turn down the volume button for more than 7 seconds at the same time, and restart the device. (Press the power button for 8- 10 seconds to restart the phone).
If it still can't boot normally, there may be a problem with the system program or hardware. It is recommended to send the mobile phone to the nearest service center for testing.
