DA0Ti7MB6D0 - TOSHIBA CLICK MINI L9W-B - schematic place help

[smaniak]

I need schematic for this tablet. It give me short on one of the phases...
I changed this voltage regulator around the phase.... but nothing.
The regulator is SND9039A1 - if anyone can find datasheet- thanks...
In the attachment there is picture on the board....

What's the exact resistance to ground on this inductor?
I'd think this is the SoC core voltage.

17 oms, and no voltage!

So yes I think this is the SoC core voltage and that it's not shorted. The low resistance is probably normal.
Something else is wrong in the power sequence. But the datasheet for this PMIC is not available, no schematics for the board, no information at all… Unfortunately not much you can do there I think.
