If the iPhone not detect on PC and stuck on the apple logo that is the fault of the trister. That is a hardware issue.

Might be the issues of middle pin of the battery check it first.

I also faced the same issues before but i solved by invest 1 hour’s time.iPhone XR has so sensitive flex with some force activity while removing makes that issue see carefully the edge of Fpc might be tore makes that issues. Clearly observe you find the solution.

There is few possible belong to that faults.The common problem with SWI issues.

First check that loud speaker option greyed out or not on call if not that is the problem related to Audio Ic.

That is the issues of audio ic that can be fixed by hardware.

Behind all iPhone the iPhone X series have so much easy solution for error 4013.Most of the other models have issues with Nand or Nand related issues but iPhone X small issues on that cases it can be fix with externaly . The mostly problem appears after water damage on Charging flex with vibration and upper flex with flood illuminator. I also fix that problem many times.This is the work that i have done makes you help to solve that issues.

Sounds like problem in SWI line the middle pin of the battery.

This is one of the common problem shown on the iPhone 8 Plus.I also faced that problem and i solved it.That problem is actually from the pin name display to MAMBA MSYNC CONNECTION pin problem.If you still stuck on that problem that is extremely helpful for you.Before doing you need some knowledge about micro soldering.Do that job carefully.

Use iTunes sometime the 3utool got some error and you try to restore by saving user data .That process sometime makes that error.Try full restore on that process the data will no longer acessable. Only the iCloud data you got.
