Need Entune 14A .iso Updates to Versions 2.x, 3.x to do 5.2 Update

Bought and installed head unit 57011 model YY050 extension box from a 2014 Prius v which appears to have never been upgraded from Entune version 1.6.

Everything seems to work except the USB port connection, which problem I hope to resolve.

As I work that problem, I hope to eventually upgrade Entune to its final 5.2 version. But that upgrade is only applicable to installed versions 3.x and higher (5.1).

I have the red 2015 vintage Toyota Entune 8GB USB stick labeled 14A that originally came with the version 2.x .iso upgrade, since overwritten by the later 5.2 .iso file.

Does anyone have stored (Dropbox, Google drive, etc.) versions that I could link to of the 14A .iso upgrade files for Entune Updates to Versions 2.x and 3.x?

Thanks.
