Is my raspberry Pi 3b+ dead?

Is my raspberry pi3b+ dead? I'm using my Pi to make a mars rover using an l298n motor driver. The l298n has a separate usb power source, and the pi has a different one. While connecting the ground of the l298n to the Pi's ground, I think I connected it to the wrong pin (not entirely sure). The lights dimmed, and i pulled out the jumper wire almost immediately. I was pinging the pi from my PC, and it started showing the no route to host stuff. An SSH connection was on, it got disconnected. I decided to reboot my Pi by directly removing the cable (I had no other choice). And then, this happened. I was powering the l298n and the pi with USB cables coming out of my PC. My pi just shows the red PWR light when a power is connected, and the green ACT light does not turn on at all. There is no damage to the SD Card reader, and I tried booting from a USB with no luck. Nothing gets hot, nothing is displayed on the HDMI, as if the pi is dead. Is it really dead? If not, what can I do to fix it? I really need it fixed fast.

can you tell us what pin you connected it to and what voltage it was recieving?

the thing is the gpio pins are directly conected to the main microchip so if you did put too much voltage into the wrong pin your practically done for

I dont remember it gpio 11,12 or near to 24

okay let me check

Ok tysm

ok this is what I always use

if you power it up with nothing attached to the gpio pins, and try a local monitor instead of pinging it via ssh or vnc or something that sometimes helps

I literally just had to do that because my SD card kinda currupted

Oh ok ty for support lemme check

Hi can you read that message again

This one see

Both the l298n and the pi were connected to different USB power sources coming from the PC. I was connecting the l298n's ground pin to the Pi's ground pin.
