From March 2022, we are delivering microSD cards to customers to update their OS so that they can use future versions of MinKNOW (22.03 onwards) with the latest features.
If you meet the requirements below, you can update your device before the microSD card arrives.
Note: there is no guarantee this process will work, as not all vendors of microSD cards have been tested internally at Oxford Nanopore.

If your MinION Mk1C serial number is greater than MC-112454, your device shipped with Ubuntu 18.04 (Bionic).
Alternatively, on the user interface navigate to Settings and then Software. Click on the ‘I’ icon next to the MinKNOW version: you should see either
ubuntu-bionic
orubuntu-xenial

Complete the factory restore.
Power down the Mk1C. Insert the microSD card and power on your Mk1C. After 30 seconds you should see a System Recovery pop-up screen:
Select Factory Reset to re-image the device with the software on the microSD card.
Follow the on-screen instructions to complete the OS update.
If no screen is observed, it is likely you have downloaded the wrong microSD card OS image, so check your OS version again. Alternatively, your device needs to perform some pre-requisite actions, see the Troubleshooting section ("If your Mk1C does not boot from microSD card") for more information. If you have issues, contact support@nanoporetech.com.

Completing your OS update
All sequencing data stored in the /data folder is retained after the OS upgrade. However, please note that you may need to configure some device settings after the update.
If you use a mounted external storage to the Mk1C, you will need to remount the external storage. Follow the instructions in the Mount network drive section in this user manual.
If you cannot connect to the internet (you may see the error "Unknown connection 'static'"), follow the instructions in the (Advanced) Network configuration - static vs dynamic IP section in this user manual.
