This morning I closed my switched off Huawei to the charging cable and then wanted to turn it on after a few minutes but it did not work. There was also no indication of how full the battery is already and it has flashed red. Even if I remove it from the charging cable, it continues to flash. I do not know how I got it back. Does somebody has any idea?
Did you let it load for a longer time?
I know this only if the battery has been discharged very far. Maybe something is broken, if the phone can no longer be charged. The socket on the hands, the battery, the cable itself or the power supply would be conceivable.
Try to keep all buttons pressed at the same time and if something happens then.
With my old Huawei Honor, it has happened before that it simply did not want to tackle. The long press of all keys then made sure that the phone has booted into a menu from which you could reset, among other things, the phone. I then closed this menu again by pressing the on button and then the phone went off again!
