Chosen Solution
I recently changed LCD screens on my OPPO phone and the motherboard cracked at the side because it’s a very thin strip of plastic and it’s easy to crack when you remove it out. Now, because of the crack, the power doesn’t travel well from the battery to the north side of the motherboard and the phone is switched off. However if I apply pressure on the crack, the phone lights up and works really well. But if I let go it switches off again. It sounds like a really silly thing, is there any way I can repair this? Cause if I get the power to travel through the tiny crack, the phone works as good as new. I would hate to throw away a phone that I know can work really well just because of a silly crack. Any ideas?
Nick, You did not state which model of Oppo phone you have. Posted a couple ifixit guides below that show how to replace damaged mother board(guides state easy to moderate in R&R) hopefully will work for you if not try a search using your (make,model#,disassembly). Also do a search using your model # for a replacement board to see if cost effective. Good luck. I hope this helped you out, if so let me know by pressing the helpful button.

Hi Nick As Christian said it will be very very hard if it is more than a top and bottom layer and how much money do you want to spend finding out? But Nice! I like these types of repair, so fulfilling when you get it done Now lets assume it is a part of the board that only has a top, or and bottom tracers You can get “Wire glue” eBay. You will need a magnifying glass and a steady hand and get creative it can be done if the phone is worth it to you
@nkomp18 Depending on the number of layers and traces, you can attempt to do board level repair. This would be difficult and require micro soldering. Unfortunately, boards with more than a bottom and top layer would prove extremely difficult to repair(if not impossible). If you can source a motherboard, you could swap the boards and use a backup of your data. Unfortunately cracks in the motherboard are very difficult to fix.
