S-10+ Originally AT+T USA/Now Rogers CDA - Will NOT take' Android Updates-Still on v9-How to FIX?

[HammerToe]

I own a Samsung Galaxy S-10+ purchased back in November, 2019. I purchased this phone FROM A THIRD-PARTY RESELLER THROUGH Best Buy Canada (wherein I live). The price on the phone at the time was ‘Really Good’ – roughly $500 off the Current Retail Asking Price and/so that though I didn’t really NEED a new phone, I decided to ‘pick one up’ during the Black Friday sales that were in effect at the time. ANYWAY – to the point: the phone in question was an Open Box unit or something like that BUT I didn’t really care as long as cosmetically it looked like new AND ‘worked’ which it did when I activated it with a Canadian carrier and all has been just fine. No problems whatsoever. Functionally… Except for one irritation:

Ever since I got it, the phone has never, EVER been able to ‘take’ an Android update from Samsung or my carrier and/or wherever it is I am supposed to get an update from. It is still ‘back on’ Android 9.0 (I think it is).

NOW, I THINK I might have ‘some idea’ WHY but (a) I am not 100% sure that ‘that’ is the cause AND (b) How I might be able to work around and get up to the most current release available.

As far as I know, since Samsung typically – if I recall correctly – will provide you with three Android versions of Basic OS Operating Systems support, I believe that most likely most ‘normal’ Samsung Galaxy S-10s should be up and running on Android 12.0.

Here is where I think the source of the problem might be: it becomes obvious when Android on the system ‘boots’ or ‘cold restarts’ – THAT THE PHONE had previously been (what term to use) last/originally used/activated with a US network – AT&T – because can see the AT&T logo when it boots up. (I, on the other hand, am currently using ‘Fido’ (‘Rogers’) in Canada as my cellular services provider AND I suspect that for/because of that reason – for UNDERLYING reasons I do not fully understand, somehow or other that fact is preventing my phone from receiving updates from ‘Fido’ (‘Rogers’) WHICH I BELIEVE IS THE WAY PHONES NORMALLY SEE THEIR UPDATES ‘allocated out’…

IN ANY EVENT – I would appreciate any help anyone might be able to provide as to how I might go about getting my S-10+ Android version up to – at least – Android 12.0. Ideally, though I don’t really care that much, it would be nice to have the phone boot up either as a ‘No-name brand’ or with Fido Rogers showing during the boot process.

But in any event, I would really like to finally try to get this thing up to Android 12.0 if possible, AS GENTLY AS POSSIBLE – AT THE LEAST POSSIBLE RISK OF ‘BRICKING THE PHONE’ – somehow or rather in the process?

Some technical details: the precise model number of the phone is: SM-G975U.

AND – I just double checked: it is running Android 9.0 One UI version 1.1

Suggestions (Our Most Welcome), anyone?

Thanks.
