reflow the main IC on the main board or bake the main board. These are known to have BGA issues as well.

It's not a cake !! It needs 217c to melt lead free solder.

Yes, you are wanting to re melt the solder balls under the main processor, however using an oven will all of the solder so be careful, don't bump it, open the oven door to let it cool before touching it.
Ideally with some flux if you have some although fumes in your food oven aren't the best.
