I tried to back factory settings and root but i couldnt fix it.
Do you have any advises?

@inventor2016 How long do you have the phone ?
It seems the battery is dead

Around 7 months. But this happened immediately. Before this issue my battery was in perfect condition.

Looks like your connection to Meizufans was lost, please wait while we try to reconnect.
