error -39

My iPhone 6's screen and LCD was broken for 4 days. After I got it fixed, it says "iPhone Disabled Connect to iTunes". Long story short, I put my phone into recovery mode to restore it. I have tried to update and restore my iPhone five times, and it always says "An unknown error occurred (-39)". Please someone help me out. I don't want to have to spend money at the Apple store to get it fixed. I just want my phone back.
