Share Phone Repair Guide and Provide Phone Repair Tools

Today, A customer sent us a wrong iphone 6S, and he said his phone was out of order with Repeats Booting,He asked us urgently how to help him solve this problem quickly, So today we'll show you how to fix the iPhone6S reboot problem. 1.we carefully watched the mobile phone mainboard repair situation, and found that the barometer of the mobile phone was soldered with 4 or 5 jumper wires , but we have no idea what was the fault was fixed at that time. 2. Observe the iPhone 6s motherboard with a professional Trinocular Stereo Microscope , it is found that there is a small dot near the barometer disappeared. Checking the WUXINJI schematic diagram and bitmap, we get to know it is a zero ohm resistor.  picture 10-13-1  picture 10-13-2 picture 10-13-3 3. After the short connection and installation, the iPhone 6s is tested OK. In order to ensure that the customer will not get any problems when he receives the handset, it will not be a problem i...

Today, We Received an iPhone 6 without WIFI, the customer said: "two mobile phone repair shop tried to fix it but didn't succeed". There are lots of solder flux  cover on WiFi, it seems that WiFi has been replaced several times, a nearby resistor is also lost , the bottom of WIFI is scraped to copper wire, we can certainly confirm it's not the iPhone 6 WIFI module problem. First remove the WIFI and boot device to measure the voltage of WIFI bottom board pin, we find that 14 pin has no signal voltage, it should be 1.8V. The problem comes from here. Using a digital multimeter to measure but no resistance, so we use WUXINJI bitmap to check and find it is directly through CPU, is it the bottom board wire disconnection? It can be seen from the bitmap 10-25-1 that the iPhone 6 bottom board wire is really disconnected. Now we have to see if there is another way, continue to look at the principle diagram Apple 6. As shown in picture 10-25-2 and 10-25-3. ...

If you find iPhone 6 rear camera sometimes won't turn on, you find that the camera is beginning to blur, or worse, your iPhone 6 camera stops working.Today, The VIP Pro Shop Team will show you a good way to solve this mistake. The iPhone 6 rear camera sometimes won't turn on, and there is a vertical bar when take photos. According the repair experience, first we measure the diode data of rear camera with Fluke 15B+ Digital Multimeter . Picture 14-4-1 When we measure the diode data for the 34th pin, we found it unstable. Sometimes more than 300, sometimes more than 500 (The normal resistance is about 500). Open WUXINJI Dongle to check iPhone PCB schematic diagram, we know that this pin is 2.85 power supply pin. Picture 14-4-2 This 2.85 power supply pin is converted from U2301.  Picture 14-1-3 Base on the above conclusions, we suspect that this could be caused by a 2.85V conversion tube virtual weld.  Gently shake the conversion tube with Pre...

Today, We getting the iPhone X main board 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...

If you've got problems with your Car Keys remote not working, engine not starting or you've lost your vehicle's keys then you've arrived at the right place. This is a totally FREE site providing information that could save you a lot of money and time. Today, please allow me to introduce to you some details about car transponder key. First, i will introduce to you why the car transponder key is so important. Principle of operation in a nutshell: A weak radio wave is emitted from the key and the radio signal is received by a car antenna. The signal code is identified by an electronic control unit   (ECU) and then transmitted by an actuator (motor or solenoid) to perform the action of opening / closing. The transponder key was originally a technology that used radio frequencies to determine whether an aircraft was friendly or hostile during World War II and suddenly became a major demand for car manufacturers in the late 1990s. At that time, social unrest, c...

We Know, Although battery models vary heavily from phone to phone, there are some basic criteria which hold true for most phones with interchangeable batteries. The point is, do you choose the best battery for yourself? Next, we will provide the best ways to test cell phone battery.  1. Check Appearance The most direct way is to check the appearance. A good cell phone battery features no oil stains, stains, scratches, points on the concave and convex surfaces and no cracks in the input and output points. In addition, another important area that is often overlooked is battery contact to ensure that the battery terminal is not oxidizing. Of course, a qualified alternative battery needs to be compared with OEM through a size test. 2. Test Function At this stage, a cell phone battery tester and a conversion universal instrument are needed. The specifications like battery resistance, voltage, charge and battery capacity, need to be confirmed. In spite of this, th...

In case your iPhone 8 or iPhone 8 Plus is getting very warm, or even hot, to the touch, then there's generally no reason to panic. We found that our iPhone 8 got very hot when playing AR games, but it can also get warm when you're first setting it up, restoring a backup, or using GPS and a game simultaneously, like with Pokémon Go. If it gets too hot, the iPhone 8 is designed to disable certain features, like the flash, display a temperature warning on screen, and shut itself off. - How to Fix It? Obviously, the first reaction you need to do is take a break from using it until it cools down. The most likely culprit for overheating is a specific app or game, so pay attention to what is running when it happens and consider uninstalling anything problematic. Try turning off any functions you aren't using. For example, go to Settings > Privacy and toggle Location Services off. If you're in an area with poor signal, then it may be worth swiping u...
