iPhone X Error 4013

Sounds like the phone got a good concussion ;-{

So your logic board has either suffered a solder fracture on one or more of the solder joints or a component has failed from the shock.

This will need someone with micro soldering expertise and access to the schematics and board layout drawings. It also maybe beyond that as the complexity of this logic board layout makes it almost not repairable as you can see in the IFIXIT teardown here: iPhone X 분해도 jump to Step 9 for more on the complexity of the logic board layout.

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.

iPhone X Stuck On Apple Logo iTunes Error 4013

Will you explain what happen when you try to restore through dfu mode. I don’t think there is major hardware problem. Just some loose connection or dry solder.

Try some means which can restore iPhone. Better to open iPhone and refix all cable firmly.

The usual issue with the 4013 is hardware. It is a loose HD on the MB usually and will require microsoldering.

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!!!

It might just be sweat that got into the earpiece assembly and corroded something.

I just cleaned the earpiece assembly with some alcohol et voila: it worked!

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!

So I had this same issues, read your solutions here, disconnected the earpiece and phone booted up fine. But a little backstory -

my iPhone X first got water damaged a month after I got it new, kept using it like that cos all that went bad was Face ID .

then many months and a few drops after, back glass and display broke so I decided to replace the entire chassis / hosing and display. While pulling the phone apart, I broke the loudspeaker connector attached to lightning port / charging port flex- bought a cheap replacement and put the phone back together then it got stuck on the boot loop.

so I’m trying to understand what exactly causes this, I didn’t damage the earpiece so why is disconnecting the earpiece the solution?

if I buy a different earpiece, will it work ?

what did the rest of you do to your phones that got it stuck on the boot loop ?

If you buy another earpiece speaker the phone will

boot normally however Face ID will be unavailable as I believe Apple has paired this part to the board.

I’m not entirely sure about the other stuff though. When you reassembled the iPhone did you connect your faulty earpiece speaker or was it only the replacement loudspeaker connected when the phone began to boot loop upon reassembly?

I had this issue too! After disconnecting the earpiece I still had the same issue but after replacing the back camera the phone would boot up regularly.

After some overconfidence in IP67 dipping it into the pool (after a screen repair- which probably reduced the effectiveness of the seals) I encountered the same boot loop issue on my iPhone X.

I tried to put it into DFU mode and restore and got the 4031 error every time.

After disconnecting my earpiece speaker/sensor assembly as pointed out above, I didn’t observe any corrosion and it was still unable to restore out of DFU mode (still error 4031) with the flex disconnected.

After some troubleshooting through disconnecting the camera and charging flexes I was still unable to restore out of the 4031 error.

Then it sprung to mind that it could be the charging assembly at fault but I was stuck in DFU mode (no untethered boot). I used the ‘PhoneRescue’ app (can use any equivalent app) to exit the device out of DFU/ramdisk mode.

I then disconnected only the charging assembly flex and voila! It booted with no issues. Now all I need to do is replace the charging assembly.

The iPhone X bootloop issue may also be due to the charging flex as well as the earpiece assembly -just make sure you’re out of DFU mode.
