Logic board is perfect, no oxidation.

Recognizes in DFU mode but does not complete (revive and restore)

PPBUS_G3H - 12.30v
PP3V3_G3H_RTC - 3.3v
PP5V_G3S - 0

I checked the U6960
pin 11 - 12.30v
pin 10 - fluctuating between 10 and 11.8v
pin 13 - 5v
pin 5 - 0.8v

changed the U6960, voltages did not change.

checked the R6970-73

can you help me with SoC ROM? My first time with this process. I searched the forum, read about different adapter because of 1.8v.
