Customer said that 3/4 solder joints have been dropped when he had the storage expanded. After jumping wires and rooting, iTunes reported error 4005 and screen displayed white Apple logo. Repair Process When I receive the motherboard, it has no EEPROM and many jumping wires on PCB with green oil . After observing the outer looks of the motherboard, I use multimeter to measure the diode data of all the solder joints and they all have data. But, comparing these data with that I get from my previous repair cases,I find that pin G5 should be about 700 and J5 should be about 500 (notice: different multimeter shows different data). While these two joints is about 700. The two data should not be the same. I guess that someone must jump the wrong wire. when scratch the green oil carefully, I find that there is a wire and a via. Measure its diode data. The data of wire is about 700 while the data of via is about 500. Now I can be sure that the customer has jumped the wrong wire. R...

I will share bad and good experiences about iphone repair guide,it will help all of us who use mobile phones,if you interest pls let me know. The situation of electricity leakage is divided into two kinds, one is when iPhone 6 not booting, it will shows leakage or large current alarm on UD 1505TA DC power supply . The other situation is no electricity leakage when supplying power, but it will show large current once pressing power button. The battery voltage is PP_BATT_VCC first sent to charging IC--U1401, then U1401 will output main power PP_VCC_MAIN to the  related circuit, battery voltage PP_BATT_VCC and main power supply PP_VCC_MAIN is sent to the related board after supplying power, if it shows power leakage or large current not booting, it must be one of the PP_BATT_VCC and PP_VCC_MAIN circuit has a short fault, first measuring the ground resistance of PP_BATT_VCC and PP_VCC_MAIN. Use rosin  to smoke the circuit into white, add voltage on short circuit parts and ...

When your Phone 6 Fingerprint Function Failure,you need check your finger is sweat or there is liquid on your iPhone, you need to wipe both your finger and your home button. Inductor 1500 easily corroded damage caused by water damage, which will cause U1503 can not work normally, it's necessary to replace if the inductor gets damaged. Since the small glass U1503 IC voltage value is 3.7V  (VCC_MAIN) when iPhone is not booting and it has high voltage output value 16.5V when working, so if the IC gets water in, it would very easy to be damaged or short, which not only cause the fingerprint recognition failure but also cause leakage or high current when connecting with Rigol DP832 DP832A DC power supply . The HOME button signal passes through the 3 tracks of the interface J2118 and then passes R2160 to iPhone 6 CPU . Here we should notice that the resistance R2160 is easy to corrode and causes the HOME button unresponsive, it can be short connected by jumper wire  to solve...

Anyone need a phone repair? how to fix iphone 6 fails,Please refer to the following analysis, Customer reflects the fingerprint of his iPhone 6 fingerprint got unresponsive, after recovery, the phone reports error 53 and unable to reboot again. Disassemble the iPhone 6 device and use DC power supply  to test, when power on the iPhone 6  (click the power button moment), the current value reaches 200-250MA. The current value of normal iPhone should be around 50-60 Ma. It is obvious that there is a leakage of electricity. Leakage and fingerprint failure, it can be preliminarly judged that the iPhone 6 fingerprint part has electric leakage phenomenon, resulting in fingerprint failure. And for the error 53. First, measure the 2 power supply of fingerprint. 3.0V voltage is measured low. The value is very close to short circuiti! So it can be judged the problem is 3.0V short-circuit, which caused by low power 3.0V on fingerprint so that it would get unresponsive, for err...

To get your iPhone 6S fingerprint failure fixed.Check circuit diagram of iPhone 6S fingerprint line interface on WUXINJI Dongle , the difference with iPhone 6 is that the iPhone 6S has more circuit. The left of the fingerprint line interface circuit map is control signal of fingerprint; the right part is new function--Force Touch, also called pressure feeling control. According the iPhone schematic diagram, we know that the power supply of fingerprint has 3 circuits, one is 1.8V, one is 3.0V and another one is 16.5V. If the 1.8V and 3.0V is abnormal, it cause fingerprint failed to turn on, these two voltages can be reached to fingerprint interface when you press the iPhone power button. The voltage of 3.0V and 1.8V is supplied from iPhone power IC . If the circuit of 16.5V is abnormal, it will cause the iPhone can open the button that adds fingerprints, but there is no response when you add fingerprint. This voltage will be measured 16.5V when the fingerprint is opened and the iP...

How to fix iPhone 6S won't boot and leakage ? If the iPhone shows leakage when it was supplied power, it's usually because BATT_VCC (battery voltage) or VCC_MAIN (main power supply) these two circuit lines short circuit, the other case is that when supply power on it, but it is not leakage. After iPhone is turned on, its standby current is about 100mA, this case mostly was caused by USB control IC is damaged. The iPhone 6S battery  voltage passes the charge IC and then output the main power supply VCC_MAIN. If provide power on iPhone but is shows leakage or large current, then we need to use Digital Multimeter  to measure the diode data of BATT_VCC and VCC_MAIN! If there is a short circuit, we can apply some rosin on the iPhone motherboard component, use hot air gun to smoke it, and supply voltage on short circuit line, the voltage starting from 0 and gradually increasing, and then you can find the short circuit parts. In this part, we have to add voltage on short circui...

The iphone camera is very important in our daily life, such as traveling and taking pictures, capturing some good moments. Sometimes front or rea camera can't be used normally, it is a common problem of the mobile phone.It's sad. If the same problem is found on your iPhone 6S, how should you diagnose and repair it? 1. Rear Camera Repair First, we take out WUXINJI schematic diagram  and read the power supply circuit diagram of iPhone 6S. There are three circuit of power supply in total: One of the circuit is 1.2V PP1V2_CAMERA from the power supply IC, the 1.2V power supply was sent to rear camera interface J3200 through inductor FL3201, if the voltage is not sent to the iPhone 6s rear camera interface, it is generally caused by FL3201 corrosion, use jumper wire to do short connection will solve the problem.
