Encountering iPhone 5s Error 4013 in iTunes - Possible Motherboard Issue?

iPhone 5s
After starting the phone, a picture is displayed informing about the need to connect the phone to iTunes.
ITunes throws error 4013 when trying to restore the phone
The phone can be switched to DFU mode and is detected by the computer and iTunes
This is not a problem with the computer or the USB cable, because the same iPhone was successfully restored on the same computer with the same cable.
I changed the motherboard of the damaged iPhone to the working one but still when I try to restore I get the same error, so the problem must be in the motherboard.

Any tips?

Verify the magnetic field sensor system (compass), PCB damage, Baseband eeprom and Tristar system. It is possible to logically or physically damage the NAND memory or the CPU-NAND connection.

I examined the CD carefully and noticed that there were missing parts right next to the battery socket, four of them were still there next to it.
FL11
C279
C23
C25
C275
C22
C9

Capacities can be ignored, but fill this FL11 bridge.

I'm a fan of ...
Pulling the screen off, I moved the U15 and the capacitors next to it.
The capacitors were put in place, I took off the U15 and now the phone does not show any signs of life ... neither under the USB nor under the charger.
I don't know if it makes sense to continue fighting with this album ...
Why not buy an iCloud disc and reschedule the layouts?
Will the plate get up without U15?

I do not think so. This is a touch control chip.

I don't think you know what you are writing about ...

You are using too high a temperature and you probably overheated something while downloading U15.
You would have to connect the phone to the power supply and check the power consumption off and after pressing power.

First, you would have to know what the current condition of the album is and what else you can do with it.

The icloud boards on the element dose are perfect besides the CPU, you can get everything you can

In the meantime, I took off the NAND and refilled the FL11 C279 C23 C25
The question of how to remove this black glue? Removing the NAND, a bit of the mask from my memory was torn off, but it's not a problem, I will paint it with the mask again.

I set the voltage to 4.2V, only connected plus and minus, I don't know if you need to cheat the board somehow on this third pin.
after applying voltage, consumption 0mA
after pressing power 508mA consumption unchanged

and now a surprise
when I connect the USB and give power, the computer shows the message not recognized device without pressing power, consumption 214 mA
after pressing power there is no change in consumption.

Previously, there was no reaction after plugging in the USB ... strange

On the connected USB, as I hold home and power after 10 seconds, you can hear the disconnection of the device, I let go of the power and the device is reconnected, but still not recognized.

When I connect the phone with the battery, the charger draws 0.24A - the battery was almost full.

So something else works out there

You have a stick, if you downloaded nand memory then probably CPU / RAM

There is a short circuit on the PP1V1_GPU line

Added after 16 [hours] 46 [minutes]:

My guess is I should take my CPU off now to see what's next?
