The iPhone 6 is burned out when charging, it still can't work after repaired. We can see from the picure, the iPhone 6 motherboard pins drop very seriously! And most of the components on the motherboard are removed so that results the phone cannot work well.
For those motherboard whose pins drops seriously, I have to replace it with other workable motherboard. That is to say, remove all the major parts to other workable motherboard. Find a iPhone 6 motherboard in the picture.
Remove all the chips and tin them. First solder main power supply, USB charge management chip, charge field tube, NAND Flash and CPU and so on, as shown in the following.
Then turn it on and it can display normally, as shown in the picture. The previous parts are soldered normally. Next I continue to remove the small parts.
After removing all the parts. Turn it on and get into IOS to test. All the functions are normal. “about iPhone” can display all the serial number, as shown in the picture.
