I realize belatedly that I did not think of giving some advice about the problem of returning back to a newer version once the goal of revert to a previous one has been achieved.
It would be easy to imagine that it will be easy, but it's not as straightforward as following the usual procedure.
When going from 1.1 -> 1.2 -> 1.3, history of these upgrades was recorded.
If the phone is rudely returned to 1.1 and the user asks it to update back to 1.2, it will look at this history and conclude 'I have nothing to do !'.
So the way to go in this case is to delete all this history in the lower part of the phone screen by swiping to the right and pushing the red trash button for all theses updates, and then the normal update behaviour will be restored back to normal.
