Tech support mode - rdynsxtrs/rn4bin GitHub Wiki

In case you find yourself completely locked out of your ReadyNAS system, "Tech support mode" may be the last chance to get control back without having to do a destructive "Factory reset".

Before turning to "Tech support mode" make sure it's your last option. Try "OS Reinstall" first, it's much safer and non-destructive.

Turning on "Tech support mode"

  1. Power down the ReadyNAS.

  2. Access the Boot Menu by pushing the reset button and keeping it pressed while powering up the device. Release the reset button when “Boot Menu” is shown in the display.

  3. Select "Tech support" by pressing the backup button until the option is shown in the display. Confirm by pushing the reset button again.

  4. Log in via telnet to the IP displayed on the ReadyNAS with the following super secret Netgear Tech staff only account (Google is great some times): root / infr8ntdebug

Mounting the volumes

Once logged in you're in a Busybox shell with no drives mounted. To get access to your volumes run

echo DEVICE partitions > /etc/mdadm.conf
mdadm --examine --scan >> /etc/mdadm.conf
mdadm --assemble --scan
mount /dev/md0 /mnt

Your original boot drive is now accessible through the /mnt directory. Should you need access to your data you just have to mount /dev/md2 to a different location.
