Fixed: iPhone 6 4013 Error


We are going to fix a iPhone 6 today, according to our customer's description, the main fault is that the iPhone 6 reports 4013 error when reflash it with iTunes. How shall we repair it? Let's check in the article!

Frist, connect iPhone 6 to the computer with iPhone lightning cable, and then use iTunes to flash iPhone again, we found the white Apple logo appears properly but can't enter the normal mode and reports unknown error 4013.

The iPhone 6 reports 4013 error is usually caused by iPhone Nand flash or CPU problem. In this case, frist we need to remove the iPhone Nand flash, and then use iTunes to re-flash the iPhone, finding that the iPhone can enter the normal mode and report 40 error, seems it's the iPhone Nand flash problem.

The iPhone 6 reports unknown error 40 is normal thing when the iPhone Nand flash is not installed. Use JC Pro1000s Nand problem to read the data of the original iPhone Nand flash, and then write this data to the new iPhone Nand flash, but we found the data of the iPhone Nand flash couldn't be read.


Therefore, we can only use the iPhone IMEI to find the original iPhone Nand flash SN, BT and WIFI address. After find out this information, use iPhone Nand test fixture to write these data to the new iPhone Nand flash, and then install Nand flash to the iPhone logic board by QUICK 861DW hot air rework station.


Reinstall the iPhone 6 and re-flash the iPhone via iTunes, the flash process goes well. Activate iPhone and test it, all functions are working properly, the repairs end!

iPhone 6 Display Failure after Replacing LCD

The iPhone 6 display is black after replacing LCD. After checking, the diode data of display socket is normal and all power supply for iPhone display IC  output is normal. Testing by  DC power supply , we find the iPhone current is abnormal. When press the iPhone power button, the boot current is obviously large. The current reached 100mA when press the power button. After remove the display tube, the current still the same, which means there is a short circuit. Measure the voltage output of each circuit of power supply with Fluke 15B+ Digital Multimeter , then surprised to find that there are really short circuit places. LD010 is short circuit; we suspect that the filter capacitance on the circuit has been penetrated. After remove the iPhone power control IC , we found it is ground short circuit. Open the WUXINJI Dongle  to check the iPhone schematic circuit, we found that this circuit is the display card image transmission MIPI data bus power supply. CPU brea...

Solution: Why iPhone X Voltage Keeps Jumping

After getting the iPhone X motherboard to test, we observe the current value repeatedly jumps between 0mA and 50mA on DC power supply , and it is different from the normal booting current. Next, test whether the power supply of every circuit is normal. PP_VDD_MAIN is measured 4.2V; PP_VDD_BOOST measured is 4.2V. PP1V8-ALWAYS is 1.8V, all the values are normal. But when testing PP1V1_S2, PP0V8_SOC_FIXED_S1, PP1V8_S2 and other circuit voltage that output by power chip U2700 voltage are jumping constantly. According to previous experience, voltage jump is usually caused by a power supply circuit of U2700 output. Measured with digital multimeter , there is no short circuit was found for the dipole value of all power supply to ground. We repaired iPhone 7P before and know that if crystal oscillator is false welding can also cause voltage jumping, And if iPhone CPU  power supply is abnormal also can cause voltage jumping. Check the crystal oscillator we find no problem, then check th...

Iphone 6S Enters DFU Mode Cannot Start Fault Repair

The customer said that he did not know what the reason was. The mobile phone has been restarted indefinitely and can enter the DFU mode. However, when the flashing machine fails to enter the recovery mode from the DFU mode, and then the mobile phone is connected to the computer for 5-10 minutes, it automatically enters the recovery mode. After we received the 6S that could not be started, we disassembled the power with iphone engraving tool and turned on the power to 100mA. First of all, check if you can connect and read the DFU mode after connecting to the computer. Wireless DFU can not exit, we can only brush the machine to view the error. Refresh Aisi and iTunes respectively. If you stuck on the progress bar for a long time, it is very likely that the error is -1. If the progress bar does not enter, you can roughly determine the probability of a CPU failure. Now we need to see if there is a problem with the hard drive. First, use DC power supply for iphone repair, the hard disk o...
