Before you fix iphone 6 error 40, you need to do something as following:
1. Check whether the NAND flash chip is pseudo soldered or damaged by measuring related resistance.

2. Replace the NAND flash chip.

3194 is usb cable or charging port connector? Are you kidding me? How many iPhones have you restored?

check shorted capactiors near nand and do check nand voltage if there are no shorted caps
