Jeez, you removed the PMIC?   Ouch.  Don’t do that again.[br]

[br]

The PMIC will always heat up for ANY short that is on one of its outputs.  Unless you have water damage (you don’t, this is a drop damage fault) then the PMIC is NEVER the cause of a short on one of its outputs in the iPhone 6.

Don’t follow guys that teach “see hot = remove hot”  That is bad repair.[br]

[br]

For short detection, you have four strategies.[br]

1. Vote the ugliest guy off the island (can’t help you here, the bad guy will appear undamaged).[br]

2.) Heat can be your guide.  (We know that the PMIC will always heat, so ignore that and see if you can find the component on the line that is heating.  A cheap FLIR cam will find this one, or you can find it with freeze spray.  Put away the alcohol, that is only for macbook short detection, it is not effective on iPhones)[br]

3.) Experience.  (This is my favorite—always the best one!)[br]

4.) Brute force.  It’s a short.  There are only so many possibilities.[br]

[br]

So for this short, the best strategy would have been #3—”Hey, has anyone seen a 3v0_NAND short on an iPhone 6 with history of drop, no water damage?”[br]

[br]

And you’d find lots of people who will tell you….[br]

[br]

YES, about 1000 times.  It is ALWAYS the 3v0NAND cap on the end of the row behind the NAND.  Flick off with a razor to solve, do not replace.  This is a 10 second easy job.[br]
