Question iPhone 6s pixelate screen and iTunes errors 14 and 2009

Sep 28, 2020
Hello, my iPhone 6s is stuck on Apple logo boot screen and the whole screen is pixelated. At first it wasn't pixelated in recovery mode, but eventually it also became pixelated. When I tried to restore it via iTunes it throws errors 14 and 2009. I did small research and I think it could be GPU related, but I will appreciate every suggestion form you guys.
