Finally, to the question of whether there is a warranty after root you mentioned:

Because the device will obtain the highest control authority of the device after rooting, and the device parameters can be modified arbitrarily, including the hardware parameters, it is easy to cause the risk of hardware damage caused by modifying the hardware parameters, such as CPU overclocking causing the CPU to burn out, adjusting the speaker parameters to cause damage after the speaker volume is overloaded, etc. Therefore, based on the existence of the above risks, Lenovo currently has a corresponding warranty policy for users who root their mobile phones:

If the product cannot be used normally due to the customer's own flashing or rooting, the maintenance station host will judge whether there are other faults caused by software modification (such as crashes, viruses, or even serial number tampering, hardware damage and other problems).

1. Yes: The product is a failure caused by human reasons, which is not guaranteed, and does not continue to provide normal warranty;

2. No: The site can charge users for the service of flashing according to the out-of-warranty charging standard. After brushing back to the official system, the product can continue to enjoy the three guarantees.

Note: The above fault judgment is subject to the inspection judgment of the maintenance station.
