Fixed: iPhone 7 White Apple Logo Stuck on Screen

When iPhone 7 restarts automatically, the white apple logo appears on the iPhone display, it can't enter the iOS system and the iPhone can flash, but the second time, iPhone 7 automatically restarts, and the flash memory process is not completed.


The iPhone 7 originally needed to repair the audio part because it could not be recorded and could not send voice at WeChat or WhatsApp. For this audio failure, we can fix it by replacing the new iPhone audio. However, after replace the iPhone audio, the iPhone 7 always white Apple reboot.
First we thought maybe it's the iPhone audio is not installed well, so we re-install the audio by QUICK 861DW hot air rework station, but after replacement, the problem is the same. We try to flash the iPhone, the flash process runs smoothly, but it won't be able to access the IOS system after the flash, re-flash the iPhone again, the iPhone automatically restarts.

Is the iPhone battery out of power? Replace the new iPhone battery, and then test it, the iPhone boot successfully， but something wrong, the iPhone battery power percentage is not right. Now, we realized that the iPhone battery detective pin has some problem.

Use Fluke 15B+ Digital Multimeter to test it, the data tested is normal, re-test it for several times, we confirm the problem is the iPhone battery detective pin. Check the iPhone schematic diagram in the WUXINJI Dongle.

There are Q1202 and a boost resistor, the resistor tested is good, directly replace the new Q1202.

Reboot the iPhone again, all the functions work normal now!

iPhone 6 Display Failure after Replacing LCD

The iPhone 6 display is black after replacing LCD. After checking, the diode data of display socket is normal and all power supply for iPhone display IC  output is normal. Testing by  DC power supply , we find the iPhone current is abnormal. When press the iPhone power button, the boot current is obviously large. The current reached 100mA when press the power button. After remove the display tube, the current still the same, which means there is a short circuit. Measure the voltage output of each circuit of power supply with Fluke 15B+ Digital Multimeter , then surprised to find that there are really short circuit places. LD010 is short circuit; we suspect that the filter capacitance on the circuit has been penetrated. After remove the iPhone power control IC , we found it is ground short circuit. Open the WUXINJI Dongle  to check the iPhone schematic circuit, we found that this circuit is the display card image transmission MIPI data bus power supply. CPU brea...

Solution: Why iPhone X Voltage Keeps Jumping

After getting the iPhone X motherboard 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...

Guide: iPhone 7 Plus Camera Fault Repair

iPhone camera failure is common for most of cell phone repair technicians, today, we're going to fix iPhone 7 Plus camera. According to the holder's description, the front small camera is normal while the rear camera fails to take photos, when turn on it, the iPhone 7 shows black screen. Let's start from easy repair operation: directly replace the iPhone camera to have a test.  Note: Pay attention that two camera are connected together. When disassemble the iPhone 7P rear camera , you need to pry up from the left side.  The fault is same as before after replacing a new rear camera. We tested before, the iPhone 7P double camera is rely on the bigger camera to get image, as shown in 15-5-1, the corresponding part on iPhone 7P motherboard is J4501 pin, the resistance value is normal after testing with Fluke 15B+ digital multimeter , it reminds of us that iPhone6 Plus also encountered this phenomenon, the power supply part has some problem. By checking on  WUXINJ...
