Fixed Details: Drop-damaged iPhone 7 Doesn't Boot


The iPhone 7 fell into the ground during the normal use, and then it doesn't boot. After repairing, the iPhone 7 is back to normal work, here is the fix detail.

Firstly, use phone opening tools to disassemble the iPhone 7, remove the iPhone display assembly, disconnect the iPhone battery, and then remove the iPhone motherboard. 

Connect the iPhone motherboard to the DC power supply,  the boot current is large than normal, it's leakage.  Now measure it by digital multimeter, we know the 3V power supply is shorted. 

Observe the iPhone motherboard seriously, it's found that the iPhone motherboard card slot is bent,  so we suspected that possibly the problem is it. 

Use QUICK 861DW hot air rework station to remove the two capacitors next to the NAND flash, now measure it again, the value tested is normal. 

Finally, install the iPhone 7, press the iPhone power button,  the iPhone 7 is turned on smoothly.  The iPhone 7 has been fixed!
