    MS-16R61 Rev 2.0 EC not responding after repacement

    Hello adventurers

    I have this board and it came from a friend with a shorted EC.
    I have ordered a new one and replaced it.
    Now i have 4 Milliamps draw on pluging
    3VALW and 5VALW present (i know nothing about RSMRST and ECRST because web only has boardview for 16r3 and this modell looks competly different)
    For EC flash i need KSO3 KSI4 KSI7 KSI6 KSI5. These are all 3.3v EXCEPT KSO3 is 2.2V
    I have checked the FFC cable connections and they are OK.
    I have removed and Reballed the IC again, but no change.
    Do you have idea why EC not responding to programmer ?

    I have tryed to reflow the chip and cleaned everything multiple times. Now KSO3 has 0V others has 3.3V.
    Also no I have 5v on one of the test points that is next to the ec chip (TPJNC13)
    But programmer instantly saying there is nothing on the other side (not waiting like usually when power is not yet plugged in)
    Also tryed both of this configurations but no change (noticed that 2 sequence of EC programming is hanging around on the net for ms-16r61 )

    1. original programmer file contains this:
    MS-16R61 KB_pins=30 RIGHT UP 05MM KSO3=27 KSI4=11 KSI7=14 KSI6=13 KSI5=12 FLASH=160 CHIP=KB9548GF2 (Igor)
    2. others on the vinafix states that it works for them is:
    MS-16R61 KB_pins=30 RIGHT UP 05MM KSO3=27 KSI4=18 KSI7=15 KSI6=16 KSI5=17 FLASH=160 CHIP=KB9548GF2 (Lex66)

      How has KSO3 gone from 2.2V to 0V .Is there a resistor gone high

        What i suspect is that i did not used rubber gloves before and it was a transfer voltage
