ReadyNAS Duo won't update with latest firmware

I did open a case with Netgear, although they haven't responded for a while. They asked me to do an OS reinstall which I did but I don't think it completed properly. After a long time, I could see a pattern on the leds that were blinking and it looks as if it was saying that there is something up with the flash (I found the meaning of the patterns on this forum). It makes sense because when I tried again to update the firmware, this time downloading the file to my hard drive then uploading it, it said that the flash verification failed. I also found the USB ports aren't working. I bought a qualified UPS for it and it isn't recognised and neither are any USB hard drives (I tried two). So, I don't know if a complete factory reset is going to do anything here or if the hardware has gone south.
