unfortunately it didn't help. Today I will go to the service center. the topic can be closed, no solution has been found.you have to jump start your battery if you dont even get any feedback from EDL or fastboot. just plug in c type connector, then repeatedly plug in and out your charging adapter. this once brought back my old xperia xa ultra from being completely dead to back to life. also dont drain your battery past %15-20.
I'd like to know your findings from the service center or if you were able to revive your phone. Same thing happened to me. new phone arrived and the battery was drained. LED Lights flicker when plugged in but won't turn on.unfortunately it didn't help. Today I will go to the service center. the topic can be closed, no solution has been found.
