I have to agree that is is better to do it with both options activated when you are doing a manual update. I had an issue in the past which had to do with regaining the ability to perform OTA updates. It was only solved after manually getting back two versions to the former one that had been OTA updated and then reinstalling the two next versions (the one I had, which had been manually installed, and only then OTA updating the one that had been most recently released).
My opinion ever since is that running USB burning tool (V.2.2.0) with the two options marked is the way to go for a proper update. (Of course all will be lost and will have to be reinstalled again, and that can be a pain. I personnaly have screen shots copied to a computer of the apps pages so I don't forget any. )
It is my feeling that running USB burning tool (V.2.2.0) with only the "erase bootloader" activated is great when you are reinstalling the same firmware version that you already had. And it is the only way to keep what you had in the internal disk, especially if you failed to back it up. And proba

And probably you will even be able to run it ever since with no problems what so ever, as the situation I experienced could be caused by something else or simply be the one in a million that required that solution.
I don't know if this is the most popular opinion, but is the one that also works for me.
