Received a iPhone 7 with WiFi function failure, the customer is very anxious and unwilling to wait, so how to repair it in a short time? iPhone  6, 6S WIFI fault repair case is common, the NAND chip is universal, so the repair process should be similar. At beginning, the WiFi was unsuitable, so we directly replac e  a good one, and start to detect WiFi's MAC address. After installing the WiFi and reboot to test the address, we found there is no any problems. Then the next step is to remove the   iPhone 7 NAND chip . As shown in picture 1. picture 1 After that, put the NAND chip on WL PCIE programmer   to unbound WiFi. As shown in picture 2. picture 2 WiFi unbound is successful after installing to test, but the WiFi can not be turned on. Where is the problem? It's the same situation after reflashing the iPhone. In the past, 6S WiFi unbound was sometimes unsuccessful, so we remove it and unbound again, it is OK this time . WiFi is normal

Continue to focus on us, we will share more free iphone repair guide. The customer delivered a iPhone 6SP which reports error 4014 during recovery process. According to our past iPhone repair experience, we know that the 6S error 4014 was basically a NAND problem. How should we repair it step by step? 1. after getting the iPhone device, we connect it to the iTunes with lightning data cable, we find the white apple logo stuck on screen and then report error 4014 on progress bar. 2. use FLUKE multimeter  to measure the power supply 1.8V and 3V  of NAND, both are normal. 3. remove the iPhone 6SP NAND(W006) to measure the grounding resistance value of the solder pad. 4. it is found that the M6 pin abnormal, as shown in picture1,  the normal resistance should be about 1000, but the pin value is infinite. Check the iPhone 6SP PCB  pin and connect it to the external R1501 resistor. 5. After checking, we found that the resistor R1501 is missing, replace R1501, and install the NAN

If you find your iPhone 5S is stuck on some Wi-Fi problem, like iPhone not connecting to Wi-Fi, Wi-Fi keeps dropping, Wi-Fi won't turn on. The WIFI problem is one of the most common problems that iPhone users encounter，if your iPhone 5S no WIFI or the WIFI signal is poor, how to repair it? Here is the guide for it. 1. The iPhone 5S has No WIFI First test the WIFI function on iPhone 5S, make sure the iPhone 5S is in WiFi coverage, open the iPhone WIFI button, no WIFI address can be found, the iPhone 5S has no WIFI issue. Second, disassemble the iPhone by phone opening tools, and then take off the iPhone motherboard. Third, open the WUXINJI Dongle  to check iPhone 5S WIFI schematic diagram. Fourth, according to iPhone schematic diagram, measure the C103_RF by Fluke 15B+ Digital Multimeter  to check if it has power supply. If there is no power， we can solder a jump wire between C103_RF and C297，as shown in picture 1-1. If there is a voltage，and the surrounding small parts

Read this article,you will get the more about repair iphone information.the iPhone 5S has charge failure, such as iPhone can be charged when it is turned on, but it cannot be charge when it is turned off, or it reports that it does not support this accessory, or can't be charge at all. We need to repair it. Check iPhone 5S circuit diagram on WUXINJI Dongle  , we know that after plug the iPhone lightning cable, the charge voltage PP5V0_USB_PROT first passes through Q2, then to U2, and then to the iPhone power supply IC--U7, we can measure the voltage of 5V to U2 by Fluke 15B+ Digital Multimeter  at point C272, and the 5V voltage can be measured at point C304. If 5V can't be measured at C304 and C372 points, which means that Q2 is damaged. In this case, we need to short connect Q2，as shown in the following picture 1-1 Picture 1-1 If one has 5V and the other not, which means there is a disconnection. In this case, we will use QUICK 861DW  hot air rework station to sold

Hi,friend,please read this article,you will get the more abuot camera repair guide.whether it is iPhone 5 or iPhone 5S, the camera problem is basically the power supply fault, which is caused by the corrosion and pseudo welding of the base, also the inductance of channel is corroded and fall off! The following picture 1 is the basic structure of the rear camera circuit. Let's take a look at the iPhone 5S power supply part shown in the WUXINJI circuit diagram . For the L29, L30, L28, FL43 components, it is easy to cause no power supply after water corrosion, the problem can be solved by short connection, U210 and U13, the two small glass IC also easily damaged cause no voltage output, it can be short connected as picture 2. Be careful not to use hot air gun(TR1300) to remove the U210 and U13, because the Baseband chip is next to them! If you remove it with a hot air gun, the baseband chip will short. First remove the black glue from the IC and heat with the HAKKO solderi

Fault phenomenon: iPhone 7 error 4013 is reported when reboot system in data cable mode. Repair process: The most frequent problem on iPhone 7 devices is baseband part, which is often encountered by iPhone repair technicians. After 6S, if the baseband can't be identified, device will reboot with the white apple logo and not be able to enter the system. Maybe beginners will think that there is a problem with the Nand chip, no progress bar when restore system. If the baseband part is damaged, the error code can not be reported until 80%. But the iPhone 7 generation basically has a problem with the baseband. The repair process can be divided into the following steps: 1. Use Fluke digital multimeter  to measure if the capacitance is short circuit to the ground? If yes, it can basically exclude and reboot, but the short circuit of the baseband CPU fault is 45%, the power failure is 45%, and the other 10% possibility is short circuit. Most of them are easy to fix except for the i

This article describes how to repair the iphone 7 No 4G Signal after Water Damage.we received an iPhone 7 device, after inserting SIM card in, it only diaplays 2G signal instead of 4G signal. If there is only 2G signal on the mobile phone, which indicates the 4G signal parts get some problems. This situation only happens after your cell phone taking water in, the water damaged part is in the 4G signal channel. First of all, use iPhone repair tool kit  to open the device, and remove the motherboard to observe under HDMI camera stereo microscope , but we can't see nothing from it, so remove the 4G power amplifier chip. Remove the TDDPA_RF 4G power amplifier chip and measure the resistance value of the pad with Fluke digital multimeter. We found that the value of 11 pin MLB_PA_VBATT is infinitely large to the ground, it seems that the part is broken. As shown in picture 17-9-2. picture 17-9-1 Check the circuit diagram on WUXINJI dongle , we found that some voltage go to TD

If you iphone has fallwn victim to water damage ,read up on the most common water damage myths and how to safely repair a water damaged iphone in our blog. an iPhone 6S has no touch function after getting into water. How to repair step by step 1. Disassemble the cell phone with specific iPhone 6 opening tools , By careful observation with magniying glass, we can see that the traces of water have been processed by the last repairman. 2. Using Fluke digital multimeter  to measure the grounding resistance of display touch socket, we found the 30th pin(PP5V1_TOUCH_VDDH_CONN) power supply to the ground is short circuited, the multimeter value is shown in picture 17-5-1. picture 17-5-1 3. According to our previous repair experience, we try to remove the +5.1V filter capacitor of the display power to get rid of the fault. 4. Use digital multimeter to measure again, we found that there was no any short circuit parts. 5. Re-stall the iPhone 6 screen  to have a test, touch function

The iPhone 6S fell into water,and your iPhone is stuck on the Apple logo during startup and can't continue past it to the home screen,It was repaired once before, when we received it, the iPhone 6S in white Apple status and it will be restarted occasionally. After remove the iPhone logic board, we found that the iPhone U2 IC and charge tube has been replaced.Here are a number of steps you can take to get your iPhone out of leave White Apple. Check the iPhone logic board under a 3.5X-90X Stereo Zoom Microscope  14MP HDMI Camera, there are small beads around the chip, which is a serious mistake. Clean up the iPhone logic board and then replace the new U2 IC and charge tube, but the problem still the same, iPhone stuck on white Apple logo and restart occasionally. Use Fluke 15B+ Digital Multimeter  to measure the diode data for iPhone battery detective pin, the data is normal, the resistance of iPhone booting condition is normal, and the voltage also is normal.
