After removing the iPhone motherboard, we can see that the iPhone baseband power has traces of repairing.

Why does this iPhone have to repair the baseband power supply? As we know, iPhone 8 generation usually has no baseband problems. Anyway, now we need to use digital multimeter to measure the grounding resistance value for S1 to S5.

After measurement, the grounding resistance values of S1 to S5 are normal. Now we suspect that the chip wasn’t welded or the chip was damaged.

Attach the iPhone motherboard to the PCB holder fixture, use QUICK 861DW hot air rework station to heat the iPhone baseband power IC, and then use tweezers to remove the iPhone baseband power IC.

Cleaning the solder pad, apply some solder paste to the solder pad, and then soldering the the new iPhone baseband power IC to the iPhone motherboard. Now measure it again, the data tested are normal.

Now, assemble the iPhone 8 Plus, press the power button, the iPhone 8 Plus is turned on smoothly. After entering the IOS systems, the iPhone service is normal,  and other functions also are normal.  The trouble has been fixed!
