Hello! It's a pity! If your mobile phone fails to upgrade, verify whether it is in the built-in memory card, whether the memory is enough, etc., it is recommended that you try to upgrade the firmware package again (flashing is risky), or contact the after-sales service to help upgrade.

If the mobile phone has been operated with similar root, it may affect the ** upgrade function, if the system upgrade fails to boot normally, it is recommended to go to the repair station to solve the problem by flashing the upgrade.

There is a risk of flashing the machine by yourself, if the failure leads to the failure of the device, it may affect the normal warranty service of the product, if you are willing to bear the possible risk, you can go to the Lenovo official Lewen bar firmware area**Official firmware and detailed tutorial, according to the flashing tutorial to try to operate.

Like the root function, it is not 100% successful, but the success rate of some tools is relatively low, and the tools are not easy to use. You can flash your phone in the app treasure. The success rate of the tools in it is still good.

Generally, it can be successful on the first time. And the stability of the phone is also good. After you open the app treasure, find the toolbox sitting down, and you can see the root tool after entering the interface.

Hello! Sorry for the confusion.
