After swiping the card on vivo mobile phone, you need the account password. Abnormal network connection is displayed after input. How can I connect to the Internet? Please. ! !

Turn on the function of finding mobile phone. After the factory settings are restored or the firmware is restarted, the network connection error will be prompted when the password of vivo account is activated (under normal network conditions). You can press and hold the power button and the volume down button at the same time. After the word "vivo" appears on the mobile phone, release these two buttons, press and hold the volume up button to enter the recovery mode interface, select networking update to the latest version, connect to WIFI, detect the new system version to download and update, and then enter the correct password of vivo account to enter the mobile phone.
