If you have a rooted device, you most likely will not be able to install OTA updates (over the air). Factory resetting the device will not un-root the device so the best way of updating it is to do the following: Get the factory image you wish to install (in your case, lollipop) from the Google developers website Flash that image by following this tutorial ...

I tried a few methods I could think of: Wireshark the WiFi packets -> nothing adb logcat to see if anything extra info is logged -> nothing I found out thought, that most of what we see on the "Update" screen is hard-coded and only the "Improved stability..." part is dynamic. adb pull /cache/fota/update.zip or adb pull /data/fota/update.zip -> requires ...

It is possible to sideload the OTA update on a non-rooted, non-unlocked phone without losing your data (although it would be advisable to back up anything important that can't be restored from the cloud). The instructions here worked for me. This approach is not advised if you are not comfortable with working at the command line, dealing with windows ...

When doing updates, be it from OTA or flashing, you will need to wipe/clean the cache and dalvik-cache (They retain information that could cause problems as well as bootloops.) Just remember to leave system, data, and other partitions alone.

I was not so easy to notice at first that with Samsung phones, you have to note that there is also "GALAXY Apps" store. It has its own notification settings.
