iTunes error 4013 is one of the most common problems for iPhone users. iPhone 7 error 4013 is usually caused by pseudo-soldering or CPU damage, and may also be related to the power supply of the baseband PMU or NAND Flash. Since CPU repair is quite difficult, we can first check the power supply to the baseband PMU and NAND Flash. If all is well, try replacing a new baseband PMU. In this case of iPhone iTunes error 4013, the issue is resolved after replacing the baseband PMU. If the problem remains unresolved, we can try replacing the NAND Flash. If it still doesn't, check the processor.
