firmware update and contraindications

[Rokiit]

Samsung TV UE55KS7000UXZT - 55 ks7000 

in menu software update section i found the last software firmware version is the 1260, and if i try to update it say there's no any new version

but i see on community there is firmware version 1280.5 and maybe also more higher

there is a way to update the firmware from 1260 to higher, eventually manually?

Is the update process reversible?
Could this create problems with the correct functioning of the TV?

There's generally a reason why updates aren't applied - it may even be down to your location. As long as the TV is working OK I'd be inclined to leave it. After all, there aren't any security implications as there could be on other devices.

Hi @Rokiit  the latest firmware on the support site is 1260.1  https://www.samsung.com/uk/support/model/UE55KS7000UXXU/  (which you have), sometimes updates are firstly available on the website before over the air on your TV. These can be downloaded to USB and updated that way . The KS is a 2016 model, possibly you have been looking at 2017 firmware https://eu.community.samsung.com/t5/tv/tv-changelogs-2013-2018/ 

once updated the Tv firmware cannot be rolled back, sometimes  there are issues with particular firmware  but rare for there to be major problems.
