(Nitrokey Storage 2 - Windows)
You should backup all data from the device before upgrading, as firmware upgrades may destroy all data on the device (especially coming from firmware version <0.45)!
Right click on the icon of the Nitrokey App and go to “Configure” -> “Enable Firmware Update”. The default firmware password is ‘12345678’.
The Nitrokey Storage is not detected by Nitrokey App anymore once update mode got activated. You have to proceed with the instructions described below to make it work again.
If you are using Microsoft Windows Build 1809 and Nitrokey Storage Firmware 0.52 or lower, you need to use another system or if this is not feasible use these instructions to enable the Firmware Update mode.
Start the Nitrokey Update Tool and click “Select firmware file”. Select the previously downloaded firmware “.hex” file. Click on “Update firmware” to start the update process. Your device should get detected by the Nitrokey App again as soon as the update is finished.
