Samsung Galaxy Alpha Motherboard Replacement

简介

This guide details how to replace a motherboard on a Samsung Galaxy Alpha. Replacing a motherboard could fix a phone that will not turn on even when charged, or even a phone that is running at very low speeds. The phone is very fragile so be cautious when removing the screen and the phone back. These parts are easily bent and broken. By following these instructions and using great care, one can save time and money by replacing one component rather than buying a new phone entirely.
