Searching for Old software for 55Q70T TV

[MGamil]

I am facing multiple issues with this version of software for my TV 55Q70T with this software version 1462.1

Tried reset many times but no hope, issues with WIFI, hangs, and even difficult to reset the TV as the remote doesn't have numbers to enter the PIN as the numbers doesn't show on the screen while doing reset!!

Where can I find old software versions for this TV?

try the Internet archive website which will load older versions of websites, you may luck out with a previous version on the Samsung website which may still be on their storage servers

Is there an option to re-install the current software ?

from USB if you grab the download from the Samsung website
