We apologize for the inconvenience. The official system does not have root access, so it will not be there after the upgrade, please understand. In addition, it is not recommended that users root and flash the machine by themselves, which may lead to non-insurance and a series of unpredictable abnormalities.

Flashing, font modification, custom beautification, modification of boot animation effects, and settings all need to be applied to root privileges. Ling Shao will give an example. Android pepper friends must know that when they first bought a mobile phone, there were hundreds of applications in the Android mobile phone system.

If you want to delete them, you'll have to root your Android phone.

It's convenient and simple to use Tencent Phone Manager, open Tencent Phone Manager PC version, click on the toolbox to see one-click root. The one-click root provided by the PC version of Tencent Mobile Manager is to obtain root permanently, unless it is a series of operations such as flashing the machine and completely rewriting the system files, and the general ROM package contains root.

After opening "One-click Root", it is the benefits of root, one of the best advantages is that you can uninstall system applications and modify system files; The second interface is the condition for the program to detect the root of the mobile phone, because the root needs to maintain a stable connection, so be sure to ensure the stability of the data cable.

After clicking "Start Root", wait quietly, and the root will be over in about a minute.

Hello. What do you mean by "nothing"?

1. If you refer to the body data, the flashing operation can empty the usage data in the mobile phone and restore it to the original age high parameters, so the personal data will be lost, so it is recommended to back up the personal data before flashing.

2. If you mean that after flashing, the system is abnormal, such as some common functional components or the system interface is missing, etc., the situation may be due to abnormal flashing steps or accidentally flashing into the unofficial customized firmware, the source of the lack of hope to restore the system by itself, and willing to bear the possible risk, you can refer to the following link.

Please read the trade-off carefully before flashing, if you can't handle it yourself, please take the time to go to the Lenovo repair station to deal with it.

Inquire about authorized maintenance sites on the official website.
