Repair: iPhone 5S Blue Screen Reboot Repair

Blue screen reboot is a common problem for iPhone 5s device, for different users, there are also a lot of different reasons caused. In this article, we'll list 7 possible faults would happen on iPhone 5s device, hope it will help!


1. The screws in the red circles below are different from elsewhere. The screw holes below are empty, and the two screws below are motherboard. When you twist the screws, you will damage the iPhone motherboard immediately, it will cause White Apple logo stuck on screen and blue screen reboot, error 14 or 9. You need to especially pay attention to the two screws. It looks very strong and easy to misunderstand with big screws. The 5S motherboard can be easily damaged when many beginners  disassemble and assemble it.


Remove the screwdriver with a HAKKO FX-951 soldering iron! Gently scrape with the blade, you can see the broken wire! As shown in picture 2, you can connect it with a thin speaker wire.

2. U6 pseudo welding or damage would result in a blue screen reboot, error 14.

3. USB control IC--U2 damage can also cause this blue screen reboot problem.

4. power IC pseudo welding will also cause the blue screen reboot problem.

5. iPhone compass IC must not be ignored! This magic small IC will not only cause blue screen reboot, it will also cause red screen reboot, many lines of English displayed on screen, white apple logo stuck on screen and many other strange phenomenon, error and so on. When you meet the above phenomenons on your iPhone 5s, the compass IC must be replaced instead of removing it.

6. In addition, the induction cable will also cause the phenomenon of not turning on many lines of English or blue screen reboot.

7. Another kind of blue screen reboot is due to the battery or the battery interface of the middle battery detection open circuit or short circuit, in this kind if case, you can enter into the system, but it will blue screen reboot again after 1-2 minutes. Measure battery and check the resistance of pin with Fluke 15B+Digital Multimeter, after eliminating the short circuit or open circuit problem, you can replace battery to have a try.

Solution: iPhone X Won't Turn On

According to the customer's description, the iPhone X would not turn on after it drop accidentally. Then the cell phone reports error 56 when restore it. How did this happen? Let's test and repair step by step. Since iPhone X motherboard 2 layers are connected through the middle column, the solder points are very easy to get dropped. so we guess that the solder points from NFC chip to the CPU part have fell off. Disassemble the iPhone X by iPhone opening tools , remove the upper board off the main board, when separate the main board we see there is a row of points have fell off. Check the location map on WUXINJI dongle , it is surrounded by a ground wire, in fact, there are 6 useful points dropped. The ground wire does not need to be filled, the 6 useful points are added by professional phone welding tools. These are the signal wires of the NFC chip, so the iPhone X would report error 56. Then the tin of the middle column is repaired by iPhone X BGA reballing ste...

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...
