The presence or lack of a “blinking” program does not indicate whether or not the bootloader is working properly. It’s possible to have a bootloader present with blinking and it’s possible to have blinking on the “LED pin” without the bootloader.
The presence of the pattern does likely mean that the chip itself is working properly, but it is possible that the bootloader was removed (by someone else) or that something is interfering with the proper operation of the bootloader. If you’d like to send it to us for diagnosis, we’d be willing to take a look and reprogram it if necessary.
