Need T2 original file MBP15 2019 A1990 EMC3359

[guzq]

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
