First, connect the iPhone 7 Plus to a computer with the Apple lightning cable, and then use iTunes to restore it. When the progress bar runs to 20%, it stops moving and gets stuck in recovery mode.
Then, use screwdrivers to remove the screws next the iPhone lightning port, use CPB screen separator to heating the iPhone 7 Plus screen, and then use LCD opening tools to open the iPhone screen.
Remove the iPhone display assembly, disconnect the iPhone battery, and then take out the iPhone motherboard.
Observing the iPhone motherboard, it looks good. Attach the iPhone motherboard to a PCB holder fixture, put it under a Trinocular Stereo Zoom Microscope.
Use soldering iron and solder wire to clean the solder pad, and then clean it with PCB cleaner.
Now put iPhone Nand flash on the MJ 3D BGA reballing stencil, allpy some solder paste to it, and then use hot air gun to reball it.
Once done, install the iPhone Nand flash chip to the iPhone motherboard, and then assemble the iPhone 7 Plus.
