Unfortunately, ATT has modified their server settings breaking the current means of accessing the updates. I don't have time or the means to reverse engineer this, so I won't be able to update this thread any longer. If anyone out there wants to work on this, now would be the time.
All the best.

For anyone else who is sick of vague answers to how to get into the att link here's how

Also how are you able to even see the latest update on their server ? Is there a way of seeing a physical list of whatever has been uploaded to the att server?

I learned by reading through this thread and links from here to one that used to be on 4pda.ru which seems to be gone? Also, having a basic knowledge of linux has helped. You can certainly modify the user agent in your browser and do the same brute-force thing that I do at the command line with the same result. Beware that I seem to have got my IP address blacklisted on the ATT server, so use care when you look for update files. The safest way to do this is to monitor ATTs device help site and when a new software update is shown, only then try to download it from the ATT servers. This will keep your profile low and most importantly, keep your use of their resources to a minimum. Hope one of these methods works for you.

Thank you for responding. While I'm pretty good with most basic and intermediate computer related things, brute force with command line , Linux is not common knowledge for me. Majority of us are coming here to just OTA update or Odin our phones. Some of the explanations are incredibly vague around here which can be frustrating. Willing to learn but Some of the posts assume everyone knows what the person is talking about. "Go find it on Google" also gets old and obnoxious (which is a common response I've seen here). Some people get a slew of results that require perusing at the expense of lots of time.

TL;DR:

1) you aren't missing out on anything by not being able to access the att server and poke around. Everything there gets mirrored out on the mail.ru site.

2) You can educate yourself to check for these things on your own and it wouldn't hurt you to spend the time to gain that skill set. You could even put it on your resume.

3) we need to be careful to note that our access is not supported/authorized and need to treat lightly.

Long version:

There are a few dimensions to this. I agree that a tutorial would make things better. There was a tutorial that explained a lot about how this phone could be updated over on the 4pda website. I lost track of that and haven't gone looking, but that was a great resource and I was thankful for how well google translate handled the russian!

There's great value in educating yourself even if it takes you a lot of time. It would be possible to spoon-feed you and others how-tos, but that wouldn't help you learn. If you run windows and have access to the linux subsystem for it, then it's not a big step for you to learn the curl command and in doing so you will begin to open up a massive new skill set for yourself.

If you just want access to OTA updates and are outside of the US or in the US and not on ATT services, then just be patient. XDA user @khaliullov maintains a repository of all the known updates including full firmware and it's updated as things become available. We should be very thankful for this hosting. @khaliullov usually finds the updates first, or watches this thread and puts the updates on the mail.ru site as soon as they are available.

Another dimension here is that our poking at ATT's servers is, at best not supported, and at worst may provoke them to close the access. I don't think they could completely close the access as their official OTA updates likely happen via HTTP, but my IP has been banned from their server so they do apparently watch their logs and are sensitive to scanning for updates. My point is that instructing hundreds of people in how to scan their websites makes it more likely that getting the updates through the channels we use will get shut down and then there will be no way for non-ATT users to get updates in the future.

Just got a update today. I am on BRD1 for build. Seems a little more responsive. Don't think they fixed anything with that new, junky, Messages app. Anyway, I was notified today of it.

Chris
Can you give the full build number please? It's BRD1 not BRC1? I'm asking because I'm not able to download that from ATT

I'm missing something. There's CRD1 which is Oreo and BRC1 which is Nougat. The full update filenames are U2BRB5-to-U3CRD1 and U2BRB5-to-S2BRC1. I haven't seen a BRD1 either on ATT's server nor on the mail.ru cloud site.

Apologies I was thinking about the latest.
