How to Reimage

Follow these instructions to reimage your appliance. You may have been told to do this due to corruption or to debug an issue.

This procedure requires physical access to the appliance, a small phillips screwdriver, and a laptop or computer with a microSD card reader.

To obtain a reimage image, please contact us so we can generate an image for you.

Shutdown and Open Appliance

Shutdown and remove all connections from the appliance.

Back

On the bottom, remove all 4 screws.


Open 1

Use your fingernail to pry open the front edge (edge with the LEDs and command button).


Open 2

Carefully open the white portion of the case from the front edge first, then once the front is off maneuver the back edge over the antenna connector.


Remove microSD card and reimage

Card

Remove the microSD card by pressing it to eject and place it in your computer.


Linux Users

On a linux system you can use unzip and dd to image the microSD card. Determine which block device is the microSD card, in the examples below sdc is used.

ubuntu:/local# unzip sdcard_2.0.8.zip
Archive:  sdcard_2.0.8.zip
  inflating: sdcard.img
ubuntu:/local# dd if=sdcard.img of=/dev/sdc

Windows Users

On a windows systems, we recommend using ImageUSB from PassMark.

Unzip the compressed reimage image to obtain a .img file. WARNING: Windows defaults to hiding the file .zip extension even when it is still compressed.

imageUSB setup

Replace microSD card and Close Appliance

Replace the microSD card, it will click into place.

Back

Place the cover over the back connectors. Make sure the USB and Ethernet connectors are not caught on the case openings.


Side

Before closing the case entirely, make sure the back cover is flush and not caught on any connector. Once checked, snap the front closed and make sure it is also flush. Re-insert the screws, do not over-tighten.


Setup

When reimaged, the appliance will reset to defaults automatically. Attach the admin USB console to reconfigure the device.

On the first power-up, the appliance will detect that a reimage has occurred and adjust partitions, reset to defaults, and reboot itself.
