iTunes error 4013 also called iPhone error 4013,is a hardware related error which are mostly seen due to faulty Nand IC/Harddisk. To put it simply, the error is actually due to problems in connectivity between NAND IC to CPU.
Procedure:
1. Use CNC machine to grind the NAND IC.
2. Cleaned.
3. Use thicker reballing plate to reball the new NAND IC.
4. Write the original info using JC Repair Assistant
Error 9 is among the error codes that prompt during
firmware updates or system restores on iPhones or iPads via iTunes. As
described in the Apple support page, this error has something to do with
a problem with the USB connection to your device that is causing it to
unexpectedly disconnect when syncing. Mostly NAND IC failure but in this case the line of CPU to EEPROM is loose connection.
NAND, so
called because of its use of NOT AND (NAND) gates, is a type of
non-volatile memory chip that is used in all iDevices. This chip is
where all the storage of the device is located. In the case of iOS, the
chips can range anywhere from 4 GB to 512 GB.

iPhone X logic board despite packing in more connectors and components.Apple effectively folded the X board in half and soldered the two
sides together. The result is that it fits components that take up
roughly 35 percent more space than the iPhone 8 Plus logic board area
when fully laid out into something that is 70 percent the size of that
board on the whole.
