Linkstation LS520D

Disassembly
Remove the 3 screws on the bottom of the device and the two screws on the inside right side, then carefully pry the pieces apart. This is not easy.

Root Access
This device can be sent commands via ACP_Commander using the -c option, A shell-like interface is also available using the "-s" option.

Telnet
an actual root shell over telnet can be accessed by doing the following (requires the latest version of acp_commander): wget http://security.debian.org/debian-security/pool/updates/main/b/busybox/busybox-static_1.22.0-9+deb8u4_armhf.deb dpkg -x busybox-static_1.22.0-9+deb8u4_armhf.deb. cp bin/busybox. java -jar acp_commander.jar -t 192.168.1.142 -xfer busybox -xferto /tmp java -jar acp_commander.jar -t 192.168.1.142 -o
 * Download the armhf busybox-static package from Debian
 * Extract the package and copy busybox to the same directory as acp_commander
 * Use acp_commander to copy busybox to /tmp on the device
 * use acp_commander to blank the root password and start telnet

You should now be able to login as "root" via telnet. This method needs to be repeated if the device is restarted.

SSH
@Gogoli discovered you can also just the ssh daemon on the device with the following: java -jar acp_commander -jar -t 192.168.1.142 -c "/etc/init.d/ssh.bak start"

If needed you can wipe out the root password with: java -jar acp_commander.jar -t 192.168.1.142 -o

Custom Firmware/Operating System installation
https://github.com/1000001101000/Debian_on_Buffalo/wiki/Alternate-install-method-via-debootstrap-script
 * Create a Debian armhf image and write it to a USB drive using the process found here:


 * Connect the usb drive to the device, reboot the device to ensure the drive is detected (probably unnecessary).


 * Use ACP Commander to verify that the device automounts the drive to /home/USB/usbdisk1

Firmware Notes
The "recovery" image provided by Buffalo and the standard install image are the same file packaged with different instructions (at least for version 4.50).

A copy of the Firmware environment and layout are stored in a tar file which can be extracted with this command: dd if=/dev/mtdblock4 of=output.tar bs=131072 count=2 skip=34
