VESC 75/300 repair

Trying to repair my VESC 75/300

I know the STM32 is fried, so a new one is on the way.

All the power are fine, 3.3V 5V and 12V are all present after i removed the shorted stm32 and 2 fet drivers.

But some things i'm still wondering about.

1: What firmware should i flash with?
(and where do i find that file)
The PCB says version 3.1

2: These transistors, does anyone have the exact part?

3: when powering the unit (without the STM32 chip), i get different voltages on the motor output cables, 0.9V, 0.5V and 2V
Is my FETS fried? (two of the FET groups have their drivers removed as they seemed fried)
