Can't open com port

I need yo update the firmware because any button pressed turns on holld. EEPROM forced reset did not fix that. Should I attempt a flash via the programming header using an arduino nano? I have several on hand. I had many problems getting this to work but the biggest problem was a bad crystal, You need to update the instructions with a test of U4, suggesting some way to verify the crystal is working. Also my switch board never worked, and BOB4 soon failed also. I was able to bypass both and it worked for a few minutes before it froze. After that all buttons place or remove the hold.
