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 your device. Each image is specific to the appliance serial number, do not attempt to use one image on multiple devices.
Shutdown and Open Appliance
Shutdown and remove all connections from the appliance.
On the bottom, remove all 4 screws.
Use your fingernail to pry open the front edge (edge with the LEDs and command button).
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
Remove the microSD card by pressing it to eject and place it in your computer.
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 chronos_reimage_1.52_NTP200_sn220204.bin.zip Archive: chronos_reimage_1.52_NTP200_sn220204.bin.zip inflating: chronos_reimage_1.52_NTP200_sn220204.bin ubuntu:/local# dd if=chronos_reimage_1.52_NTP200_sn220204.bin of=/dev/sdc 1638400+0 records in 1638400+0 records out 838860800 bytes (839 MB, 800 MiB) copied, 268.782 s, 3.1 MB/s ubuntu:/local#
On a windows systems, we recommend using ImageUSB from PassMark.
Unzip the compressed reimage image to obtain a .bin file. WARNING: Windows defaults to hiding the file .zip extension even when it is still compressed.
Attach your microSD card reader, and open ImageUSB. Select the USB reader, Browse for the .bin file, and click Write
Replace microSD card and Close Appliance
Replace the microSD card, it will click into place.
Place the cover over the back connectors. Make sure the USB and Ethernet connectors are not caught on the case openings.
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.
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.
