Введение

If this device were to take water damage or similar issues to the motherboard, then it might seem like it is essentially unusable and must be replaced, but if you can obtain a replacement motherboard, then you can easily replace it and continue using the phone. This allows you to reduce how much of the phone is going to waste when only part of it is damaged.
