[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 i...

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.
Hi Stephen:
there is no data need to backup. RAIDar can not detect the system even i remove both drives. (my drive is 1TB / per disk)
no matter I hold reset button or not, when i power up the machine, fan is running with highest speed and all LEDs are dark.
this machine previously is running very well in 4.1.16, when i downgard to 4.1.3, it also can successfully boot up and i can login to its admin page. only when i upgrade from 4.1.3 to 4.1.4, it can not boot up any more.
I use Raw32 to write 4.1.16 img into a USB (4GB), and i plug USB into front usb slot, press the power button and hold for almost 1 minutes, nothing happened and it seems not work. i'm not sure whether i adopt the right way to boot from USB. thanks for advicing...

This looks like the correct process (described here: https://kb.netgear.com/21400/RAIDiator-4-1-USB-Recovery-Tool )
As the article notes, you might need to try a different drive. Generally older ones seem to work better/
Thanks Stephen..
it says: "Press and hold the power button on the front for approximately 20 seconds:
- you'll see all the disk LEDs blink at 5 secs, 10 secs, 15 secs, and 20 secs.
- Release the button right after the 4th blink.
- This will start the USB boot recovery process.
i will try to find another old usb to try. but i think when i hold the power button, no LED blink at all, all dark and fan is running with high speed. i think whether there is some kind of problem before boot from USB. such as some kind of native built-in boot loader (such as so called some kind of "BIOS") in ReadyNAS is damaged? if so, whether there is any way to repaire it...? thanks much 🙂
Do you have files on the NAS that you want to preserve?

Normally the fan will start at high speed when the NAS is first powered up, and isn't throttled until the NAS completes the boot. So that part is normal.
No LEDs when you hold the the power button isn't normal though. Did you try running the factory reset process (pages 15-16 here: https://www.downloads.netgear.com/files/GDC/RND2110/Duov1_NV+v1_HW_en_06Dec11.pdf) That will destroy any data on the NAS, so if there is something on it you need to offload then try the OS reinstall instead.

Nothing really that can be repaired. Failed memory can be replaced, and of course you can also replace the power adapter.
