Trouble Phenomenon IPhone 6 touch function is completely lost. Repair Process Enter system to test, finding the touch function is completely lost. After replacing a display screen , the result is the same. Remove the motherboard and observe, finding little soldering paste around touch process chip, which suggests touch control chip  and touch process chip have been welded, as shown in picture 3-13. Picture 3-13 First measure the diode data of two ends of coupling capacitor (picture 3-14) that is used to communicate between touch control chip and touch process chip. The data is normal. One end of coupling capacitor near touch control chip is connected to touch control chip, while the other end of coupling capacitor near touch process chip is connected to touch process chip. Picture 3-14 Next, measure the power supply voltage of PN5V7_SAGE_AVDDH, PP5V7_SAGE_AVDDH, PP5V1_GRAPE_VDDH and PP1V8_GRAPE. The relevant circuit diagram  is shown in picture 3-15 and 3-16. Pictur

Repair Process Connect iPhone to DC power  and enter system after power on. Then test it under the state of screen off. The working current keeps about 250mA, as shown in picture 2-45. That working current keeps about 250mA is abnormal. Continue to test every function and find the compass cannot be used, as shown in picture 2-46. Remove the motherboard  and measure the power supply diode data of compass chip, finding PP3V0_IMU

Trouble Phenomenon IPhone 6S cannot be turned on after dropping. The material object is shown in picture 2-40. Picture 2-40 Repair Process Connect motherboard to DC power  and it shows no current. The motherboard  has no marks of short circuit. Short connect the power on pin and it shows high current, which suggests that there is short circuit on some voltage of open circuit. Measure the diode data of each power supply on the motherboard and find the diode data of PP_CPU voltage is 0.002. Obviously it is too small, as shown in picture 2-41. Picture 2-41 As many components are connected to PP_CPU voltage, it will take a long time to exclude one by one. So we put rosin on the surface of each component evenly. Short connect power on pin and find the rosin on capacitor C2006 beside CPU melts fastest. The material object is shown in picture 2-42 and the relevant circuit diagram of C2006 is shown in picture 2-43. Picture 2-42 Picture 2-43 Remove capacitor C2006 d

When you iPhone 6S can’t restore and show 4013 error code You can ask for help in Vipprogrammer to get your iphone 6s trouble solved Repair Process  This iPhone was fixed before, so root it and test it. But it still reports the error code 4013. Observing the motherboard , we find the weld marks on motherboard baseband chip  and baseband power chip , as shown in picture 2-37 and 2-38. Picture 2-37 Picture 2-38 doing BGA Reballing Stencil again and weld the baseband chip as well as the baseband power chip. Then connect it to computer to root. We can see the white Apple logo appears and it gets stuck at the grey progress bar. Based on the repairing experience, we know that this kind of trouble is caused by NAND Flash IC . Use multimeter  to test each power supply circuit of NAND Flash and they are normal. Remove the old NAND and replace it with a fine removed NAND Flass. It can enter activation interface, so we are sure the NAND Flash is damaged. The faul

Introduction Have you ever come across with iPhone 6 error 9 issue? It is well known that once iPhone 6 error 9 appears while performing firmware update or system restores via iTunes, normal function becomes disrupted. And if this occurs frequently, that will be difficult to deal with. Several reasons are responsible towards the problem, and primary suspicion relates to the NAND Flash error as our previous blog has illustrated. This time we come up with a totally different solution regarding to iPhone 6 error 9 caused by insufficient soldering within CPU BGA.

Introduction iPhone users may have experienced such a frustrated moment – the screen of the iPhone suddenly freezes, and it don’t response at all. So, what repair shops usually do with unresponsive touchscreen issue of iPhone 7? First of all, clean the screen. In the second place, try a force reboot of the iPhone 7. If the issue continues, try to restore the iPhone from a Backup. Still not working? The next step is to erase it and set it up as new, which means resetting it to a factory state (remember to make a backup before doing that). If none of these steps work, then the issue may be related to physical screen display defects, since everyone may have accidentally damaged their phone without knowing themselves. In such an event, broken screen repair or LCD repair could be a perfect solution. If you’ve forcibly rebooted the iPhone 7, you’ve restored the iPhone 7 from a backup, you set up the iPhone 7 as new, and you have repaired the broken screen and LCD, and the touch screen is

Introduction Have you come through ‘no service’ on your iPhone 6? Once your iPhone got cut off, you can not use mobile data, send text messages or make a phone call. You still can connect to the internet by a Wi-Fi network. There are external and internal causes for iPhone ‘no service’ problem, which means no one-size-fits-all solution.
