Depending on whether or not you ordered just the front glass or the entire display assembly, this guide should walk you through all or most of the steps you need for replacing your screen. At the very least, it will get most of the internal components, including the motherboard, out of the way so that replacing the display assembly is easier.
Note that this guide was user-contributed. Contributing content to our site is easy and very helpful! If this guide gets you close to replacing the screen, feel free to create a new guide for the last couple of steps!
Hope this helps! Good luck, and we look forward to maybe seeing some of your advice on our guides!
