Usually the error code will match with the corresponding deal way.
As for the error 14, we doubt there happens some fault on Phone NAND flash. What we got the iPhone 6S Plus reports the fault error 14, so we need to handle it carefully.
Anyway, we still need to flash it , connect iPhone to computer with lightning cable, use iTunes to flash iPhone, the iTunes reports that the iPhone "iPhone" could not be restored. An unknown error occurred (14).
Disassemble the iPhone, take out the iPhone motherboard, and then carefully remove the iPhone Nand flash. Check iPhone bitmap on WUXINJI Dongle, and then measure the diode data with multimeter, we found that the resistance value of iPhone Nand flash solder pad M6 Pin is infinitely large.
Picture 1
This pin passes through the R1501 resistor and pulls down, there is no resistance value when measured it with Fluke 15B+ Digital Multimeter, now we're judging that the R1501 resistor is damaged.
Use QUICK 861DW hot air rework station and tweezers to replace the R1501 resistor, and then measure the resistance value of iPhone Nand flash solder pad M6 Pin again, the data is normal.

Install the iPhone Nand flash to iPhone motherboard, now the flash is finished successfully. The iPhone 6S Plus fault has been repaired.
