Dead Sony Xperia XZ1

I have an Sony Xperia that is dead. I have a lot of experience on microsoldering and reapair iPhone motherbaords but have never done Xperia motherboards. So. This is not turning on, PS showing jumping amps (0.01-0.12). I have a good known board so I wrote up diode modes of FPC’s from it. I noticed that two pins are shorted on charging FPC on this dead board (in picture red circle). In good board these pins give diode mode about 0.290. Here are pictures of that FPC. Can you help to find where the problem is? I have removed PMI8998 (charging ic or power ic?) but the short is still there. In paper here are diode readings from good board. Not gonna move to board swap just yet. Thank you guys for help.
