First, why take a chance of bricking a perfectly good set?What a coincidence. I was just considering replacing mine (PS60F8500/Australian Version) and thought to see if there was a latest FW upgrade.
The weird thing is the version on mine is v1129 but the version online on the Samsung Australia site is v1128 (18JAN2017).
I am not too sure when v1129 was installed. A few years ago i suspect? (Unable to post the link because my post count is 0? That in itself is weird as I posted many times on here albeit a couple of years ago. Has there been some sort of upgrade on this site? Anyhow i digress ... )
Would it be possible to update an Australian panel with this latest update for US Panels via the USB method? Would it hurt the TV?
Second, so far nobody sees anything different.
