How to recover the data after Lenovo's mobile phone is restored to factory settings?

If Lenovo's mobile phone has previously backed up data through its own backup and recovery software, you can find the corresponding backup and recovery software in the main menu, and find the previous data in the corresponding backup list for recovery.

If the data is backed up by a third-party synchronization software, it needs to be reconnected to the third-party synchronization software for recovery. For details of the operation of third-party synchronization software, please consult the corresponding software customer service.

If the data is not backed up before the factory settings are restored, the deleted personal data cannot be restored.

To restore factory settings:

Whether you can enter the recovery period. How to enter the recovery: In the power-off state, press and hold the "Volume Increase Key" first, then press and hold the "Power-off Key", and let go to enter the recovery after the boot screen appears. If you can enter the recovery, switch the system and back up the important data under recovery. If you can't succeed, you need to clear all data (address book, SMS, mobile phone application, etc. Will disappear).

Whether you can enter Fastboot. How to enter Fastboot: When the machine is turned off, press and hold the Mi key, then press and hold the Volume Down key, and then press and hold the Shutdown key, and then release it when the boot screen appears, to enter Fastboot.

If this is still the case, it can only be sent for after-sales inspection, and the hardware of the mobile phone is faulty.
