Chosen Solution

I want to upgrade my logic board after it un-operational, but I would like to upgrade it to the latest possible upgrade logic board for the Macbook Pro 15” Unibody Mid 2010 (A1286). I heard the boards are very similar till Mid 2012. Can anyone please help.

This would probably be the latest board that will work: Apple MacBook Pro “Core i7” 2.7 15" Mid-2012 Specs Identifiers: Mid-2012 15" - MD546LL/A* - MacBookPro9,1 - A1286 -  2556* https://everymac.com/systems/apple/macbo
