EDIT: Ok, based on Z50's comments below, I'll put up a link to the 10.3.2.2789 autoloader myself:

For my phone, as described below, the necessary file is:
Z10_10.3.02.2789_STL100-2-3.7z
Working on downloading it now, but it has terminated early with no warning twice so far, so it might take a few tries to get it right.

I'm starting to get lost in the weeds with all the various threads discussing 10.3.x for T-Mobile with WFC and don't want to risk snagging/installing an obsolete or problematic file.
Would somebody please post a link to a known-good, current, stable and worthwhile 10.3 autoloader package for use with a Z10 STL100-3 on Ting/T-Mobile in the USA? Several references to it above on this page, but no links so I'm not sure which one is being referred to.
I'm currently running 10.2.1.2156 on an unlocked T-Mo-branded phone, using the T-Mo infrastructure via the Ting reseller. No desire to be on the bleeding edge of the latest leaks, but am tired of waiting for the improvements of 10.3 via T-Mo, which doesn't look like it's happening anytime soon.
This phone is my daily driver, so if I do an install it needs to be a reliable one, especially if there's no going back via a downgrade anymore. And WiFi Calling is important to me at home in a poor-signal area; I need to hang on to that, which looks possible now at long last.
Many thanks.
