iPhone 7 CPU hot VDD Main short, did boot, now does not, no image.

iPhone 7 A1660

I’ve been repairing it for about 7hr now, the device had no image. I’ve replaced some resistors and capacitors. I’ve also replaced Chesnut. I used to have the 1v8 lines but not the 5v7. Now I don’t have either. The short originally was around 400mah. I got it down to 165mah. Now the short is 2.5amp and the CPU gets very hot. NFCSW_RF was the IC getting hot when the short was 165. I’m sorry for this being very out of order and confusing but I’ve given up at this point. Everything was fine and I don’t remember doing anything else from accidentally turning the DCPSU to 30v 5a (the default) but instantly turning it off. I think this fried the CPU.
