Has it stopped responding? Does it show the Huawei logo? Or does it just not turn on? In the first and second case we will have to resort to system restoration, a process that is also known as hard reset , where all the data on the phone will also be lost, as well as the applications.
The process is as simple as turning the phone on with the Power and Volume Up buttons at the same time. Then we will select Clear data / Reset system values . Now the phone will go into formatting, a process that should fix any problems.
In the event that the phone has suddenly stopped responding, the problem is probably with a third-party charger or charging cable . Connecting the phone to the original charger, or a quality one, can revive the device.
