I've right now noticed that there has been another update, after 20170708 but my phone claims to be updated ...at 20170708! So, how comes that it didn't show 20171011 update?
And, please, don't ask me to download it and install it via my PC, flashing ROMs and so on: I'm a simple phone user, not a technician (I'm a cabin stewardess, not an electronic engineer!)

And finally:is there a way to get it directly on phone? I mean: if I download it via phone's browser and store it on USB memory, then select "local updates" in firmware section, does it work the same way it does downloading by itself? And: how can I be sure to be able rolling it back if it doesn't work or if it messes my phone up?
Thanks and best,
Sil
