I'm trying to burn the bootloader on my mega 2560 using an AVR ISP but it was just stuck at burning bootloader.

at first i suspected it was wrong connections since i came across two different pinouts so i tried to use the pinout in the second image but i got an error, and when i switched back i got the same error. i tried switching com ports but it didnt work.

avrdude done.  Thank you.

I think it looks like some other piece of software is using your COM3 port.

Make sure that COM3 is infact the right device, then go hunting for any other running software that might be opening COMs.

Restart your computer if you didn't already.

I've also fixed strange errors like this before by opening the COM device in device manager, and manually assigning a much higher port (COM20?)

alright, ill try that

Restarting my laptop got rid of the error message, but it was stuck on burning bootloader again. I changed the COM port to 15, but then I got the error which I have already pasted so I changed it back to 3 again and got the error again. So i restarted my laptop yet again and now I am stuck on burning bootloader again.

1. Which Arduino (UNO, NANO, MEGA) you are using as ISP Programmer?
2. What happens when you "Burn Bootloader" into MEGA 2560? to speak another way -- what is the meaning of "Burning Bootloader" into MEGA 2560?

I'm not sure how much help it will be, but can you paste the error screen from the "bootloader stuck" attempt?

Alright guys, apparently the ATMega 2560 is busted

You may follow this tutorial to be sure that your Arduino MEGA is really bad.
