My Lenovo s650 has been stuck in the boot page since I formatted my phone, and I can't boot it.

It is recommended to try to forcibly shut down and restart first. Be careful not to press the volume button of the mobile phone at the same time.

In the case of frequent startup and automatic entry into engineering mode, it is suggested to restore the factory settings after operating and backing up the important information of the lower fuselage to see if it can be improved. Some important files stored in the fuselage, such as SMS, contacts, photos, software, etc. , should be backed up before the recovery operation, so as to avoid unnecessary losses;

If the problem still exists, it needs to be sent to the maintenance station for testing and solving.
