Problem uploading to board avrdude: stk500_getsyn(): not in sync_resp=0*00
avrdude: stk500_disable: protocol error, expect=0*14,resp=0*51


These are the errors occurring when I am trying to upload to the board.
I've tried all the suggestions that suggested in this. When I am trying to burn the bootloader the same error is showing.
I don't know if I got the exact error (maybe another sync error), but what helped in my case (in this order, try again every time):


Reinsert the USB cable
Use a different (shorter) USB cable
Put the USB cable in another USB port
Restart the Arduino IDE
Restart the computer
Reinstall the Arduino IDE
Go to device drivers (control panel), check for COM ports, remove Arduino and reinstall
