hello friend I need your advice again lol
board voltages:
PP3v3_g3h = 3.38V
PPbus_g3h 12.31v
PP20V_USBC_XB_VBUS 5.07V
PP3V3_UPC_TB_LDO 3.36V
PP3V3_G3H_RTC 3.39V
PMU_ONOFF_L 3.38v


I imagine that these voltages help to fix it

Looks like (already classic) T2 firmware corruption.
Already explained on the forum what to do...
