    Need T2 original file MBP15 2019 A1990 EMC3359

    Hey Guys,

    Working on liquid damaged LogicBoard MBP15 2019 A1990 EMC3359.
    Long story short now taking 20v 0A (before only 5v), i check everything and think U4770 corrupted or need re-program due to liquid damaged.

    Here what i check before :

    PPBUS_G3H = 12.30v
    PP3V3_G3H_RTC_REG_R = 3.3v
    PP3V3_G3H_T = 3.3v
    PPVDDCPU_AWAKE = 0.755v
    PPVDDCPUSRAM_AWAKE = 0.802v
    PP0V82_SLPDDR = 0.820v
    PP0V8_SLPS2R = 0.801v
    PP1V8_SLPS2R = 1.805v
    PP1V1_SLPS2R = 1.102v
    PP1V1_SLPDDR = 1.102v
    PP0V9_SLPDDR = 0.902v
