readynas duo2000 cat not boot after firmware upgrade
[background]
when i got one ReadyNAS Duo 2000 v1, the firmware version is 4.1.7, and then i upgrade to 4.1.16, because there is no SSH, so i decide to downgrade to 4.1.3(I think there must has ssh in 4.1.3) , but still no ssh in 4.1.3 when i log in to admin webpage. so i try 4.1.4. when i upgrade from 4.1.3 to 4.1.4, after reboot, it can not boot any more.
[problem]
when i plug power and press power button, only the power light(act light) and backup light very quickly blink once(green color), and then dark, all four lights are dark, and fhe fan is keeping full speed.
if i unplug the power, hold the reset and plug the power and press power button, to try to go to boot menu. such as to to default factory model, it doesn't work any more. no response.
appreciate if anyone can help. i hope i can save this machine..

What you should have done after upgrading to 4.1.16 was install the ssh add-on (found here: https://www.downloads.netgear.com/files/ReadyNAS/ADDON/4.2(X86)/EnableRootSSH_1.0.bin )
Going back to 2009 firmware (4.1.3, 4.1.4) from 4.1.16 was a big mistake. Not sure if a factory default will restore access, or if you need to find an ancient browser (or both).
What status is RAIDar giving you for the NAS? https://kb.netgear.com/20684/ReadyNAS-Downloads#raidar
Hi Stephen,
thanks much! currently, the machine can not boot any more, if i try to restore factory default, it doesn't work. becasue when i plug the DC power cable, no matter i press the reset button or not, when i press the power button, the four LEDs(power, disk1, disk2, backup) quickly blink once(green color),and then all LEDs turned dark and fan is full of high speed, no response any more.
is this machine damaged? i really hope if i can fix the problem... thanks stephen for your help..

Is there any data on the NAS that you care about?
If there isn't, then try removing both drives, and power up. Then see if RAIDar detects the system, and shows you a "no disks" status. IF it does, also let us know what firmware it is showing you. https://kb.netgear.com/20684/ReadyNAS-Downloads
What drives are you using? I don't recall exactly when 4.1.x firmware supported 2 TB drives, and if you are using something larger than 1 TB that might be a problem. I do know that 4K sector alignment showed up in 4.1.7, and you have downgraded below that.
