I apologize if this is common knowledge, but I just got a VZW S4 today that still had the old MDK software on it. As soon as the salesperson gave it to me, though, it was trying to download the software to install the update. I was able to prevent it from completing the download (and consequently install the update) by quickly turning off mobile data and not connecting it to wifi for a couple hours. This interrupted the download that was in process and eventually, the software updater showed a notification that it had basically given up downloading the update. After that, I've been able to connect it to wifi and re-enable mobile data for a couple hours and it hasn't tried again.
Anyone know the frequency with which it will try to download the update? I'm definitely going to prevent it for as long as possible, since I want to retain my ability to install custom ROMs.
