+# Scenario
+
+For whatever reason, you end up with a MikroTīk device with broken modules. Whatever you do, they
+will not disappear. Also, in my scenario – the user module was broken – one of two devices never applied
+any update, and the other even did not remember most changes.
+
+The solution is to:
+
+1. Uninstall all packages that can be uninstalled (except for system)
+1. Disable all packages that cannot be uninstalled (mostly because they are bundled)
+1. Place an update to the device's root
+1. Reboot
+
+You will then end up with an updated device, no other modules installed, and in 2/2 cases for me
+all setting were still present. Of course a backup prior to this is still highly recommended.
+
+This folder contains an example rsc file managing the actions on the device and an example script
+copying the update and firing the rsc.
