Nec 3500ag and lite on dvd vanished

I tried to flash my drives 1 being nec3500ag and they both became disabled! I tried to do the dos thing and it won’t recognize drives to put firware back on. I will be honest, I don’t know what I’m doing and I need instuctions froma A-Z if there is anything that can be done… :bow:

Took care of it…Thank you all for you help! :rolleyes:
