High resolution image of Samsung J200G Motherboard needed

Jinu · July 18, 2020

Hi Folks

My Samsung Galaxy J2 mobile has a broken motherboard. I am trying to join this back by using jumpers, but for that i need a high res image of the section highlighted in yellow in the attached image. Thats the area where the motherboard broke. The black line indicates exactly where the board broke. I have the service manual of this board, but unfortunately it does not give the schematic of this section, just the block diagram

I need to see how the the tracks across the two sections are joined so that i can use jumper cable to connect it across.

So if any one can help me with the image it would be appreciated. Thanks

Not gonna happen. That is a multi-layer board that will be impossible to solder to properly. Even if it was feasible it's not worth doing on a phone like that.

Was plannin to do this more as a learning exercise. But your are right this is a multi layered board and initially i thought only the ground plane or power plane would be going through the middle layers, but given what i can see of the tracks, there seems to be signal tracks also going through the middle layers.
