Samsung A12 Mother board

My A12 was not listed as a choice, so I chose the A10 to start this thread. Sorry:)

I have a Samsung Galaxy A12 that will not power up. Took it to a repair service that replaced the usb board and the battery, but it did not help. They said it probably needed a mother board, and charged me 50 dollars:) Not sure if they put the old board and battery back or not. Decided to take it apart on my own. Can’t really tell if they replaced anything

I found a mother board but need to opinions on whether that really would be the problem. Not sure if I replace the mother board whether anything else will be required for it to properly work with my A12:)

I have all the parts laid out, labeled and ready to replace.
