Dear Lenovo mobile phone users, hello!
According to the description, the phone cannot be turned on, it is recommended that you try to disassemble the back cover of the phone first, remove the battery, and then turn it back on to see if it can enter the system normally. If the problem persists, we recommend that you take the time to go to your local Lenovo after-sales service center and let the engineer help detect and solve it. You can log in to the official website to check the address.
In addition, if the mobile phone is abnormal due to the deletion or modification of system-related programs or files due to the third-party firmware or root, you need to re-flash the phone to restore the use of the system. Due to the risk of flashing the machine by yourself, if you have experience in flashing the machine and are willing to bear the possible risks of self-flashing, I personally recommend that you can go to the official Lewen bar firmware area of Lenovo**The official firmware and tutorial of your mobile phone, please operate carefully. A360 firmware** address.

2.It is recommended to check to see if a data connection is open. (Press and hold the top of the standby screen and pull down, you can find the data connection icon, if it is gray, please light up);
3.If the data connection has been turned on, confirm that the SIM card of the mobile phone is enabled for data service and can access the Internet. You can see if there is no Operator's Access Point (APN) under Phone Settings - Wireless & Networks - Mobile Networks - Access Point Name.
If not, it is recommended that you add an access point by yourself (the specific parameters need to be provided by the operator). If the access point is displayed, it is recommended to switch to other access points to try it;
