My Lenovo A369 installed one click root, and then uninstalled the software that came with the system

We're sorry for the confusion.

I'm sorry, because there is a certain risk of rooting, dismantling the forest and may affect the normal warranty status of the device, the official does not encourage users to obtain root access by themselves, please understand. At present, we do not provide root-related technical support, please consider carefully to avoid unpredictable negative results caused by improper operation. If you are willing to laugh at yourself and take the risk, for the A390 model, I personally recommend that you check the following link:

Please read it carefully and weigh whether to do so.

After rooting, it is recommended that you do not delete the software and programs that come with the phone at will, if you do need it, it is recommended that you ** a "deep uninstall of system software" through the software removal, this software will automatically identify which can be deleted!

Deep uninstallation of system software.

Use a flashing machine. Master connects the phone. Just click on root.

The easiest way,Use one-click root (it is recommended that you still use a third-party flashing tool to crack root,z4root just gives you a method,But it's all the same,That is to crack root,You can try bell pepper,Zhuo master,Brush elf,,360,Mung bean,Deep flash, etc.,,,,If it doesn't work,Try the phone crack,Kingroot,Z4root.）：

2. There will be two options after opening, the first is temporary root, that is, after reboot (reboot), it will be restored back to the non-root state, and the second is permanent root, after using the second one, we no longer need root permission when we reboot the computer.

3. After selecting an entry, the software will automatically root the phone, which is very convenient without us operating manually.

4. After a period of waiting, if it is successful, an icon of authorization management will be added to the software menu, with this icon, it means that our mobile phone has been successfully rooted, and now you can use it how you want.

However, Z4Root also has many shortcomings, Z4Root is not omnipotent, and it cannot support all Android phones for rooting, and those who can't use Z4Root for root can only root through other methods.

However, the failure rate of the software method is not low, and the flashing method is generally more reliable, and there are various tutorials for various models on the Internet, so it is usually not recommended to use the software method.
