Software update of Sony Bravia 2015 to v. 5.457 through USB is not possible

By recent posting of various problems after a factory reset, I realized that despite automatic updating, software on my TV set is PKG 5.433.0183EUA. I downloaded from this community (as it is no longer available on Sony site) the latest v 5.457 "sony_tvupdate_2015_5457_eub_auth.zip" unzipped and copied to an USB stick. Error message appeared: "The system software cannot be updated by the use of this USB. Please remove the USB stick..." USB stick is anyway OK. How can I update Sony Bravia 2015 to v 5.457?? Should it be the only file on the USB? Should it be only in unzipped form, or no problem if both files (zipped and unzipped) are on the USB stick? Is there any web source apart from Sony site from which I could directly install?

@jcsaba

UnZipped, only file present, in the root of the USB not any subdirectory, and no you can’t get it from any other public source I know about.

If it still won’t update, then your TV has decided this update isn’t suitable for/compatible with the TV, and is trying to save you from bricking it.

I got the solution: I downloaded "sony_tvupdate_2015_5457_eub_auth.zip", but I need "sony_tvupdate_2015_5457_eua_auth.zip", so eua instead of eub. By which should I have known it? With the file eua, the update was successful. For all, who seek updating, look, which version suits your TV set.
