Knowledge base 135: Recovering a Sigma Series reader which has bricked during a firmware upgrade

Problem -
Occasionally during a firmware upgrade on a Sigma Series reader, the process fails due to network drop out / USB disconnection or other issue and the reader will ping but you cannot connect via MBTB or the web browser and also the USB port doesn't work.

Solution -
  • Firstly if the reader bricked during a network upgrade you should now plug in directly to the reader to rule out another network drop out.

  • Now open Morpho Tool Box (Can be downloaded from www.controlsoft.com)

  • Do not attempt to connect to the device as this does not work.
  • Select the device settings from the left 

  • Then choose "Firmware Upgrade" from the top menu

  • Browse to the firmware file you used earlier and select "Upgrade"

  • You will be presented with a command prompt window, please wait for this to complete, the reader will restart during this process if it's successful.

  • Once the reader comes back online you should be able to connect via MBTB and also the web browser and the reader will be functional again.
