What if the mobile phone can't be turned on normally?

If you use a vivo phone, you can refer to the following solutions:

1. You can try to restart the device forcibly to resume use;

① ① models of funtouch OS 3.2 and subsequent systems: press and hold the "power button"+"volume reduction button" 10 second at the same time;

② Press and hold the top round key 10 second or more to forcibly restart the mobile phone (NEX 3/NEX 3S is applicable);

③ Model of the system before ③Funtouch OS 3.2: Press and hold the "power button" for more than 12 seconds;

2. Try to repair the system by "System Repair Mode", as shown below:

Step 1: When the mobile phone is turned off or restarted, press and hold the "power button" and "volume up button" for 3~ 10 seconds, and the screen will light up. Release the button until the word FASTBOOT appears on the screen.

Step 2: Press the volume button to move the cursor to "Enter Recovery", and press the power button to confirm entry until the word "Restore" appears on the screen. At this point, the device has entered the recovery mode;

Step 3: Select "Install System Software" in the recovery mode interface, and then select "Update the latest version by networking" according to the prompt to repair the system.

If the above methods can't help, I suggest you take your mobile phone to a nearby service center for testing and processing, enter the official website-My-service outlet of vivo, select a province or city to inquire about the address and contact information of the local service center, or click the webpage link to search for the address of the service center.
