The 4 seconds make me believe that the processor has failed in the middle of something. That doesn't look good.

Could a corrupt bin file be responsible? Could a JTAG unit bypass the bootloader? A real JTAG connection (the pins are inside the case below the number plate area) might help. It can bypass the processor firmware and serial access. There is a sample open-ods configuration in the SF repository. Good luck!
