Performing a do-it-yourself (DIY) repair on an iPhone is possible. Still, people encounter multiple problems if they are not trained, experienced, and adequately tooled. So, you may only save a little money off the professional phone repair price if you are fully qualified. Some DIY repairs can result in the phone being inoperable or damaged, so it will not work correctly.
The first challenge to performing a DIY iPhone repair is that Apple uses unconventional screws, so you need nonstandard screwdrivers to open the case and take the device apart. Second, Apple uses screws of different lengths, so you must keep track of which is which. Using a screw that is longer than required for some spots may cause damage to the motherboard. Once taken apart, the third challenge is that adhesives keep certain parts together, meaning that you need the correct chemical to remove the adhesives.
Fourth, repairs needing replacement parts may not result in the phone working properly, even when using Apple-supplied parts. Finally, if the iPhone gets wiped without turning off the Activation Lock and you lack the password, the phone is not repairable. It is only suitable for supplying replacement parts.
