Vivo X80 pro DIMNESTY 9000 [repair help?]

[lastd]

So recently I came across vivo preloader exploit that can help flashing your device in locked bootloader state (for downgrade reasons in hope to be able to unlock bootloader)

After many successfull flashes I accidentally flashed full vivo x80 firmware. (DO NOTE they are using same soc)
And now the preloader isn't being detected by the PC. (And if the phone is booting to system is still not recognized)

The only thing that is still being recognized is fastboot (but it isn't helpful at all)

So I decided to disassemble the phone in order to get the phone being recognized by PC (and it isn't, I assume because it tries to go into the preloader)

The phone is seen as unknown device (device description failed)

Is there any way to get it back running again? Or is the test point I found not the actual test point?

Any help and ideas would be appreciated

I've attached the two pictures of what I found to be the test points

What would be needed to repair the device? I've read about (JTAG/ISP) from a thread in this forum. But this is above my knowledge.

It literally is giving me the same info as if the phone is on charging USB cannot be recognized.

It still can boot into system and fastboot just fine

(Except screen isn't working due to x80 firmware)

Fastboot is recognised also so is BROM.

but not preloader or when it's booted.
