Hey! I bought my iPhone X for 100€ on “eBay Kleinanzeigen” (the equivalent to craigslist) . The Screen was shattered at one corner and it had the iTunes-logo showing up. This thread here is great and helped solving my problem, BUT: When you can turn it on without the earpiece, it isn´t necessarily a logic board fault!!!

If it doesn´t work out with your phone, just try this: https://youtu.be/JM-04aWOVnw I hope that I was able to help. Greetings from Germany!
