ReadyNAS OS 6.9.1 F/W Update GUI Access + USB Drive issues

I have many reboot but does not work for me. 

I have a ReadyNAS 102, after I updated to Firmware 6.9.1, when I try to access it through the web it said offline, I used admin page and check Ready Cloud was off. So I turned it on but I was still unable to access it. So I recheck, it was on but when I refresh the web page it was off. So I try to turn off ReadyNAS, the power light start blinking I wait for couple of weeks, but the power light was still blinking, so I unplug and plug again, but it goes blinking, now I can not access admin page. I tried with OS reinstall (with boot menu) it looks change something because I have to use the default password but admin page is still refuse to connect. At this point I worry for my data. I installed RAIDar it find the readyNAS but admin page fail, browse show empty, locate works (make blink the light), download logs fails and with diagnostics I got ...

Now I am planning to install two brand new disks and apply factory reset to see if this make hardware work again, if this go well I will mount the old disks and see if I can get my data back. If the hardware do not come alive I will claim the warranty but How I get access to my data?
BTW I already try start it as read mode with same result, can access data.
