use pins 17,30,31,32
i try that method, i get BAD Vdd, Vss N/A, reset N/A, BKGD N/A

on a side note,
i also try, PINS 17, 32, 48,47. i get bad BKGN
Pins 17,32,59,60, i get bad BKGN
Pins 17,32, 77,78, i get bad BKGN
all this is being done with 5v usb power. i also try 5v external power to upa.

above pinout works for me, don't have to lift any pins, i also use original UPA , if it doesn't work for you then i would say your mcu is dead
