SOLVE: iphone 6s stuck on apple logo - Click here

There are some problems，when your iphone 6s Displays White Apple Logo, What should you do, What is the complete operation to fix the fault? Let’s follow the vipprogrammer offer guide fix it.



Step 1: First of all, turn it on to test. Screen shows recovery mode (also called data cable mode). Use iTunes to root and ascertain the problems. When the white Apple and grey progress bar show, the grey progress bar stops here.

Step 2: If iPhones 6S and its later series have such problem, the NAND Flash, CPU or baseband are damaged. Use i4 assistance’specialized function to root it and find the faulty place.

Step 3: When white Apple shows, the device UDID that i4 assistance reads are 0, as shown in the following picture. UDID exists in NAND Flash, so NAND Flash is faulty. And, the white Apple shows very quickly when rooting (the time from that i4 loads IBEC to that it gets into recovery), which suggests that CPU recognizes NAND Flash. Thus I can be sure that NAND Flash is broken.

Step 4: After replacing NAND Flash, the rooting goes on smoothly. Trouble is removed. The material object is shown in the picture.



Step 5: After activating it, I find that iPhone can connect computer, but it does not present charge. Considering that customer has changed the USB Control chip, the chip may be broken. Tear down a USB management chip from a iPhone 6 motherboard. Then connect it to computer and it presents normal charging process. The no charging problem is excluded. The material of U2 USB control chip is shown in picture. The USB management chips of iPhone 5S, iPhone 6, iPhone 6 Plus, iPhone 6S and iPhone 6S Plus can be used universally.


Step 6: We had better preheat the NAND Flash, if we want to remove it. If it is not preheated, CPU upper board is very likely to have bumps. Although the bumps are not at the right back place, too much air between the upper and lower board will cause bumps at upper board.

My iPhone Got Wet! How To Fix iPhone Water Damage?

Image
 Water damage tends to worsen with time, and it is among the more challenging DIY repairs to undertake, so this guide covers the basic iPhone repair of water damage.  1. Remove iPhone from the water and Turn it off Remove your iPhone from the water as soon as safely possible. Minimize the length of time the iPhone and water are in contact to minimize corrosion. If your phone is still on when removed from the water, attempt to turn it off. If it's off, do not attempt to turn it on. 2. Check External Ports Check any external ports (charging port, headphone jack, SIM card slot, etc.) for corrosion as well. These may have to be cleaned out with alcohol and a  Anti Static Brush , or replaced if cleaning is not practical. Pay special attention to cable ends, battery contacts, connectors, pins, and fuses, as these parts are prone to corrosion and can easily cause the phone to malfunction. Test all the buttons and features (such as the microphone, s

How To Solve iPhone X Voltage Jumping Issue

Image
Today, We getting the iPhone X main board 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
