Help locating short in iPhone

[caphair]

Hi guys I'm working on an iPhone 6s+ that has a short on the vcc_main line.

I've soldered a wire to the vcc_main test point and applied power from bench supply. It draws 3 amps but I can't feel anything getting warm.

Ive also tried using freeze spray, nothing. Usually doing this makes it evident what's shorted but this time it's not.

Any tips on how to locate the faulty component?
