Hey, daniellefromoakwood.

I see that iTunes on your Mac or PC is providing an error code 0xE8000015, and you'd like to get it fixed. I'm happy to help.

If iTunes doesn‘t recognize your iPhone, iPad, or iPod -- When iTunes isn't able to recognize a device, it can show an unknown error or an "0eX" error. Follow the steps in this article.

Take care!

In addition to the things to check already listed, this error can (rarely) mean that a non-Apple service facility has replaced parts in the phone and has installed parts that are not up to Apple's specs or standards.
