Yes it will. However that’s sort of an extreme solution. Money wise, and work wise. As long as the logic board is in good working condition, the donor board, you’re good to go. These security measures are a bit drastic, so far the only solutions are blowfishunlocks.com. Which could help you with your problem. Finding a sympathetic cellular retailer, that’s willing to lift the lock, or replacing the logic board. Which again, is expensive and a lot of work
