What we try here is to make sure you don't go about trying them randomly, because it will make easier to fix. Read More: Introduce the Best Battery-Activation Tool for You 1. The 6 iPhone Plus can be normally used before, there were no any problems. But after changing the iPhone Nand for memory capacity expansion, it reports error 4014 when flashing it. As shown in picture 1-1. 2. When we flash the iPhone device, it displays error 4014 before progress bar showing up. It is restored and the serial number could be recognized, which appeares after Nand expansion. This is usually caused by the iPhone USB chips leading to CPU problem. We get to know it UMT motherboard after disassembly, then remove USB chip U1700 to measure resistance from solder pad to CPU, we find that AP_TO_TRISTAR_ACC_UART6_TXD shows the infinite value, as shown in picture 1-2 and 1-3. And AP_BI_12C0_SDA is also broken, as shown in picture 1-4 and 1-5. 3. The layer wire is disconnected, so we need to find out other connection point or digging for other holes, AP_TO_TRISTAR_ACC_UART6_TXD is direct connected without other external components, when digging the circuit AP_TO_TRISTAR_ACC_UART6_TXD we find that there is a hole next to socket, dig it to solder jumper wire. As shown in picture 1-6, 1-7 and 1-8. 4. AP_BI_12C0_SDA has a test point outside of the iPhone circuit board, welding directly from the test point. As shown in picture 1-9 and 1-10. 5.

The phones play an important role in our life, we are getting more and more inseparable from our phone, but after a period of using the mobile phone, there will be more or less problems. How to solve these problems is the next things that we need do. When you use the iPhone, the screen, battery, motherboard, glass back, usb charger, etc, will has some problems. Now Vip Fix Shop Team will give you some methods to solve it. Good luck for you. Read More: What To Do When the iPhone Home Button is Broken After disassemble and test, we find the iPhone 7 plus is severely corroded by water. So in this case, we should observe the corrosion under a microscope first, and then the corresponding phone schematic diagram to understand the role of corroded components in iPhone. Rip off the motherboard sticker that can be ripped, and remove the iPhone PCB shield cover that can be removed. According observe, we find the most serious is the display backlight part. Now we can clean the iPhone motherboard first, and then measuring power supply C3405 with multimeter, it directly to the ground, careful observation under the microscope found that C3722 was severely corroded. After removal, the diode data of the main power supply becomes 298. At this time, connect it to power and phone standby leakage 30mA, press the iPhone power button, the iPhone screen is lit, but the left screen is dark. Leave it alone, enter the IOS, and insert the SIM card to test, we find there is no 3G、4G, the fingerprint is normal. It not only stuck on fingerprint setting, but also the restore network, restore all settings. Observing it under the microscope, we found that FL3901 corrosion seriously caused the left iPhone backlight IC cannot supply power. After soldering jump wire, it's back to normal. Picture 1-1 Then found R7109 corrosion damage caused the power supply to high-frequency power amplifier circuit impassability, resulting in no 3G and 4G. After soldering jump wire, it's back to normal. Picture 1-2 Now we're going to solve the problem that stuck on iPhone. We want to backup first and then brush iPhone, then we found it can connect to PC, but when you connect to iTunes, it times out, dis U2 cause it? So we replace it with iPhone 6S U2 IC, but the problem still exists. So now we directly use DFU mode to forced brush iPhone. However, when the progress bar shows 60%, it reports unknown error 56, re-flash several times, it still the same, the unknown error 56 most caused by NFC. iPhone Baseband CPU、camera power supply could also cause the problem, but these function all is normal, so we judged NFC. Observing NFC under the microscope, we found that it had a little corrosion. Picture 1-3 Remove the NFC, and measure the diode data of NFC, we found the G2, D5 and C7 all is connect to ground. From the phone circuit diagram, these three points are connected to the NFBST_RF, as shown in picture 1-4, we directly remove it, G2 still short circuit. After remove the C7517, the resistance is normal; D5 and C7 also back to normal. Replace the chips on motherboard, and weld well, flash it again, it still reports unknown error 56. Water-damaged motherboard power supply is the easiest to burn, so we remove shield cover of iPhone CPU. It can be seen from the schematic diagram, there is a group of power supply PP_VDD_MAIN_NFC converted by NFCSW_RF which from main power supply, so we can weld the jump wire from the A1 pin to the A2 pin. Picture 1-5 Brush the iPhone again, now it can be successfully brushed iPhone. Enter the IOS system and test all functions, now it is not stuck on iPhone fingerprint setting, seems it was caused by system issues. Now, the iPhone 7 Plus has been repaired! Picture 1-6

Read More: iPhone X Issues: Burn-in Screen, Crackling Noise, Paint off etc The Fault: The iPhone 6S home button is unresponsive, when I press it, long time no response. There is one or two times a day will turn into recovery mode. Repaired the CPU and WiFi, 32.768, 24M, NAND were also replaced before, the fault is still existing. The description is shown in picture 1-1. Step 1. Test the iPhone 6s motherboard with multimeter, boot current and power flow is normal, so charge on the side. An hour later, we find that home button has no response by pressing several times. The iPhone device could be lighted by pressing the screen-lock button, but home buttion is responsive after screen is locked, so the fault was judged as wake-up delay. Step 2. Measure BURRON_MENU_KEY_CONN_L, the home button voltage is about 1.3V as normal valure, considering the peer has changed the iPhone WiFi, clock, CPU, so the fault is locked in the fingerprint button scale. The original picture is shown in picture 1-2. Step 3. According to observe on the picture, we get to know the board is without print, we doubt the iPhone 6S CPU has been doing the real-time test to whole device hardwares after booting, this motherboard has no original fingerprint key. Fingerprint key does not match, so it's suspicious that the CPU has been repeatedly verify if the fingerprint key is matched, which leads to wake-up delay, standby sleep phenomenon. Step 4. Next, we're going to disconnect the fingerprint so that it doesn't work. As shown in picture 1-3. After disconnection, the phenomenon of delayed wake-up disappears. We test again before shipping it back to customer, it cannot be turned on now, measure the current with 70 Ma, connect it to the computer, which displays recovery mode, but does not display the model. As shown in picture 1-4. Step 5. It cannot identify the model, we find the resistance on phone bitma and measure whether the pull-up voltage is normal, the result is only 1.65V. As shown in picture 1-5. Step 6. Remove a 240 ohm resistor from the scrap motherboard to change the pull up voltage. As shown in picture 1-6. Step 7. After the 240 ohm resistor is switched on, the iPhone 6S main board is perfectly repaired. As shown in picture 1-7.

This might seem like a nightmare, but anything is possible. While the new generation of iPhone could be water-resistant, it isn' t entirely waterproof. The most terrible thing is that the iphone camera doesn' t work properly, when you reboot the iPhone after water damaged. You can' t go back in time and save your iPhone from getting dropped in water, but you can make an effort to prevent iPhone water damage. VIPFIX have the fix guide of iPhone 6s rear camera can' t work after water damaged. If your iPhone has the same problem, read on and try to implement these quick solutions. Read More: The cost only $150 to unlock iPhone X Face ID We got an iPhone 6S from customer, the problem is the rear camera cannot be used after water damaged for a sometime. We replace the new camera, but the problem still the same, so we remove the motherboard and start to repair. Observing it under a microscope, and we found that power supply pipe of rear camera was been burnt down, as shown in picture 1-1, take out it directly. This chip is converted to 2.85V by main power supply chip VCC_MAIN, and then to rear camera, it supply power to front and rear camera on iPhone 6, but it only supply power to rear camera on iPhone 6S. After take out the chip, we found the pin of main power supply was been burnt down. Because this chip is too small and hard to replace, direct short connect is also undesirable and unstable, night photography is not clear, so we want to borrow 3V voltage to here. We heard there is a 3V test point on the motherboard which near the middle plate iPhone screws. But there are four test points, and we're not sure which one. We shave one and then turn it on, measure it with multimeter, we found this one is the 3V test point. As shown in picture 1-2 and 1-3. Solder a jump wire on it, as shown in picture 1-4. After test, it can take pictures. Apply green UV oil and assemble iPhone. Picture 1-5 What's surprising is that the customer sends the phone back on the next day, and he said all was fine at the beginning, but the phone was in serious heat at night, and then it cannot turn on. Why is that? Measure it with multimeter, it shows large currents directly, the resistance value of iPhone battery interface is normal, which means the main power supply short circuit, most of this is caused by the breakdown of the capacitor. So we' re still going to follow the routine burning process to repair. Apply rosin on the position of main power supply, and then start to burn. Many peers use 2A power multimeter to do it, but direct burning doesn' t work. You can use battery which in mobile power supplies to do it, as shown in picture 1-6. One side connect machine, one side connect the position which is short circuit, but until the tin wires were melted, there was still no change on the back of the iPhone motherboard. Look at the front of motherboard, we found a little black which in the place of fix the camera problem. Check it more carefully, we found this point was burnt out; the PCB board also was burnt. There was a lot of black dust when we shave with scraper blade, that's why the phone is so hot. Seriously clean the circuit, but the resistance is still low. We need to keep cleaning it up, so we continue cleaning it under the microscope, until the short circuit problem disappears. picture 1-7. Apply the green UV oil on this point, after baking it with the UV glue ultraviolet light, we install the camera 3V on it. We're worried that the motherboard is still hydrated, so we bake it at 130 degrees on the heating platform. At the end, assemble the iPhone and send back to customer.
