Yes that at least is correct.
What about doing what I suggested and posting the track layout then we could see what sort of a mess the PCB has been made of the PCB.
The schematic is irrelevant, it depends on how that schematic is converted into copper tracks. Did the "friend" who made the PCB layout use a schematic capture program? If so what was it. Also have you told your "friend" what happens when you apply power?
Yes you have probably fried that IC as well.
Have you tried seeing if there is a short between the 3V3 and ground with your meter.
