This is when you’re certain that the device is on but all you see is a black screen. You may be able to hear it ring when a call comes in but still you won’t be able to answer the call because your device won’t respond or shows nothing on the screen for you to tap.

The iPhone 6s was damaged by dropping on the floor, which has no any response when pressing power button to turn on. Sometimes it can be online, but sometimes cannot. The fault description is shown in picture 1-1.

Online state is not normal, drive also displays incorrectly, as shown in picture 1-2, this phenomenon is usually caused by virtual soler on CPU. This device was fell over by customer, so we can judge that the reason must be the virtual solder. After soldering CPU, the iPhone 6s can be normal online, but it displays error 4013 when flashing system.

The error 4013 is reported when the progress bar just appears on screen, as shown in picture 1-3 and 1-4

For iPhone 6S device, if this phenomenon happens, which are generally baseband problems, so we remove the baseband, indeed some tin points come off. As shown in picture 1-5 and 1-6.

Make jumper on the disconnected but useful pin, install chip on it, but it still shows error 4013 when flashing, seems there is still a problem exist. Rooting the device repeatedly, we find when white apple appears, baseband S3, S4, S5 voltage can be instantly measured with power

supply besides S2, but we still can measure the ground value on S2, is it the baseband power failure? Remove the baseband power supply chip, by the way of measuring its pin, it is found that the 91 and 97 pin of the baseband power supply chip are blocked. so we can see the problem has been found here, as shown in picture 1-7, 1-8. Remove the inductance, its pin has been damagd.

The front is good while the reverse falls a pin. As shown in picture 1-9.

So we replace the damaged parts and install original fingerprint, the progress bar is normal when flashing now, as shown in picture 1-10 and 1-11. The repairs ended here!
