Lenovo P780, I logged into the SMS display system without authorization and got the factory format, but it still doesn't work. What about brushing the machine?

Hello, thank you for choosing Lenovo products.

I'm sorry for the inconvenience.

According to your situation, it may be that after the system uses root, the system carries out authorization management, but the short message cannot be used normally because it cannot be authorized. You can check whether the authorization management application such as super user is installed in your mobile phone, and set the SMS as authorization.

If the normal settings cannot be made, you may need to brush into the official system for recovery, but there are certain risks in self-brushing, and the unsuccessful brushing will affect the normal warranty of your equipment. So we don't recommend that you brush the machine yourself. You can choose to go to the local after-sales site and ask the engineer for assistance.

If you are willing to take your own risks, I personally suggest that you refer to the following link:/? q- 109339.html

Contains related firmware and tutorials, please read the trade-offs carefully before brushing the machine. If you can't handle it yourself, please refer to our suggestion and go to the maintenance station to handle it.

Thank you for your support to Lenovo and wish you a happy life!
