First press the power button 10 seconds or more to see if it can be forced to start. If it can be turned on, please back up important data and restore factory settings or upgrade the latest software version.

2. If you can't force the phone to start, please verify whether the phone has power. If plugged in, there will be charging instructions. If it is just charged, it may not start immediately. Please continue charging for a while, and then try to start.

Third, if it can't be recharged, please contact the after-sales service.

4. If there is a response when the phone is turned on, but it does not enter the system, it is recommended to enter recovery mode to restore the phone to the factory and try again (recovery mode entry method: press and hold the volume reduction+power button to turn on the phone).
