Solution 1. Hardware replacement or repair
iPhone error 56 is usually caused by a faulty hardware. It could be your USB cable, but you could test it by using other USB cable manufactured by Apple. However, if the problem were the chips soldered to the mainboard, you might want to send your phone to Apple service center for warranty claims. If it is out of warranty, please send it to a mobile phone repair shop for chip level diagnosis and ask for an advise.
To troubleshoot an iPhone with a hardware problem, apply a Device Firmware Update on it multiple times. If Device Firmware Update (DFU) did not fix the error 56, this may give a conclusion that a faulty hardware on the iPhone is causing it.
Reheat the CPU or the NFC chip
You might want to try to reheat your NFC chip or CPU if it is out of warranty, but be advised this could damage your iPhone completely. If you are technically-inclined, get a hairdryer, cover the all electronic parts while exposing the chip you want to reheat. Use the dryer to heat the chip, then restore your phone.
