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.
