If I want to change from the latest weekly update to an older weekly update should I always install as first installation or can I install as update? I tried updating only but what happened was that it had a message "wait until all apps or phone has been rebooted" and I could not open any app, maybe I did something wrong but can someone tell me the proper approach to this?
Even if sometimes it may work as an "update", the recommended strategy is to do it as a first install.
