Carrier Unlocked vs. Factory Unlocked vs. Carrier & eBay adamant GSM & CDMA different

Carriers and vendors on eBay have been adamant that a SM-N960U phone is different, and you cannot use Note 9 phones that came from GSM wireless providers on a CDMA networks and vice-versa. They become incensed and assume a position of superiority at the very suggestion that the differences between network today are often handled by changing firmware. With all of the US Note 9s being the same hardware, this is my take on where they are coming from.

1. If it says carrier unlocked for example: AT&T, it will only be compatible with GSM networks (GSM networks---AT&T, T-Mobile, Cricket, MetroPCS by T-Mobile) - My interpretation is that's only true if you don't flash SPR, VZW, or XAA/U1 firmware, and even then that is not necessarily true in the 4G range.

2. If it says factory unlocked, it will work with all networks-- both CDMA and GSM - My interpretation of that is, it seems their idea of "Factory Unlocked", actually means the phone is running the XAA/U1 firmware.

3. Their refusal to even entertain the possibility of a single model with different firmware working across all of the US networks stems from a long history of cell phone models only being able work with a single wireless provider's bands and proprietary technology.

Correct me if I'm wrong in my logic.

I don't think you can accurately generalize "them".
[Samsung Galaxy Note 9 Questions & Answers] bober10113:
i wouldint be surprised that alot of the postings on ebay have the same device under different carriers or just simply generically stated as unlocked. they want more than just 1 result popping up to make it as visible as possible. whether this is legal or not is something to debate with ebay. but i wouldint be surprised savvy vendors would be doing this and depending on which posting was bought, would simply flash carrier firmware or u1 firmware. there are also the ones posting 2nd hand handsets that might have initially been on one build and and along the way was flashed and sold under its original device banner because they looked up product code/serial and sold it as that. also not to mention phones still on contract which can be a time bomb.

Ebay's a jungle. but if you know your rights and have the right arguments to prove your case, you can return almost anything. and if that doesn't work, 2nd stage is a case with paypal.
[Samsung Galaxy Note 9 Questions & Answers] IT_Architect:
I've also been noticing the fine print on the listings that quite a few "good deals" state in the fine print that it is on a contract.

I'm just sticking with there is no difference in the hardware and they are all the same hardware all capable of the GSM and CMDA bands with the proper firmware, no matter what they say about not being able to work with Verizon, and that I can take it to Verizon or T-Mobile. The only thing I might believe is one of them who said it work work with everyone but Sprint, whose issue is most likely based on an IMEI restriction than any capability of the phone.

or on some mdm lockdown as its a rental phone or something and flashing is not an option.

Just bought a refurb Note 9 from Amazon...

I realize this is an old thread.... but it is just what I've been wondering.

I bought a Samsung Note 9 phone, labeled (somewhat conflictingly) as completely unlocked but (later on) as only a GSM phone. The model number on the phone is N960U1. That's on a printed label on back of the phone and in the software settings (UI 2.0, as 2.1 hasn't come out yet with this model and T-Mobile[??]). However, I note that lifting the sticky label, the original on chassis number beneath it is N960U (a carrier specific phone).

I thought I knew about phones - I've flashed two other (make that 3 other including my wife's) older Samsung Note phones w/ custom roms because I was tired of being back with Marshmallow.

But fundamental questions I have:

1. Is the N960U phone the exact same phone hardware wise as the N960U1?

2. In other words, is the software lock the *only* difference between these phones?

3. And does that mean I could presumably, once my phone (unlocked by whatever provider once had it locked) is identified as an N960U1, run it on GSM, CDMA, and have access to any and all services offered by whatever provider I choose?

And finally, which is where I began all this, will this phone update to the UI 2.1 eventually as an unlocked phone with that specific (still not available) N960U1 update? Or is the phone in some state of being "neither fish nor foul" - that is, not *really* a fully unlocked phone?

I am asking all this because I could still send it back to Amazon if it is less than it ought to be and get something else.

It is currently running the June UI 2.0 update from T-Mobile....

Thanks for any thoughts. The deeper one digs, the more questions come up.
[Samsung Galaxy Note 9 Questions & Answers] shonkin:
Thank you for this. Very helpful. I'm not sure yet whether I'll send the phone back.
[Samsung Galaxy Note 9 Questions & Answers] shonkin:
UPDATE: Samsung released the T-Mobile update to UI 2.1 (dated July 7) today, August 11 2020.

NOTE: I installed this and hit an issue after the install completed re an error message (see photo). This error apparently is happening in a widespread way, and the 3 solutions offered by Samsung did not work. What *did* (I think) work for me was to go to Settings > Software Update > UICC Unlock. Beneath that button on the N960UI it reads (as it should) "Your device is unlocked to support any sim." I click it anyway and I get a report that my device sim is restricted, bla bla bla. I hit the "OK" and reboot the phone to see... and sure enough, that's all it apparently took to remove the annoying nag about the install not having completed. In fact I get a successful "handshake" message between T-Mobile and the phone having formed a more perfect union or some such.
[Samsung Galaxy Note 9 Questions & Answers] IT_Architect:
You can flash between any carrier U and U1 firmware at any time. The only thing you need to be aware of is the boot loader version, which is the 5th character from the right in the build number.

- It must be the same number or higher.

- You cannot flash backwards to a lower number.

E.G. You can flash from a newer version of Android to an older version PROVIDED the older version does not have a lower boot loader version. If flashing the newer version of Android changed the boot loader version to a higher version than the older operating system supports, you cannot flash to the older version of Android ever again. The boot loader version is not synched with the the Android version. It is synched with the particular build. Thus, you might get an update to the current operating system that increments your boot loader. If you like to always be on the latest version of firmware, this is no likely to be a problem.

For the SM-N960U/U1 phones, the various carrier versions, U, and the U1 version are released at the same time. A lot of standardization has occurred and made possible by the hardware being the same. In the U1 versions for the SM-N960 you will see carrier names associated with different downloads. It's all bogus. The downloads are all exactly the same with the same module names, size, and the same MD5 signature.
[Samsung Galaxy Note 9 Questions & Answers] shonkin:
VERY helpful info here.... as of this morning Samsung updated my phone w/ UI 2.1 T-Mobile files. I posted on it elsewhere as a recurring error popped up. Surfing the web shows that error cropped up for all sorts of people doing the 2.1 update on various carriers. I *think* I found the solution but have posted it enough places (including a few posts back in this thread) I won't do again unless someone here wants it. Samsung's "solutions" (all three of them) do not work. Oh, I think I'll hold on to this phone rather than switch out for a T-Mobile specific... gives me more lattitude down the road when I feel like rooting it. Ha!
[Samsung Galaxy Note 9 Questions & Answers] IT_Architect:
As far as the difference between the one you have and T-Mobile, there isn't any difference. If you want T-Mobile specific, simply flash their firmware. The upside nearly all of T-Mobile's network was late to the game so their network had little non-standards-based legacy to deal with and thus works very will with the U1 firmware as well. You can always switch back and forth. Different carriers have different MEID ranges. A few carriers, such as AT&T might deny you based on that number not being theirs, but it is not a phone capability issue since the hardware is the same.

You cannot root any of the U phones at this time that I'm aware of. There has been talk and they've been able to do it soft of but not without serious snags in functionality. All N960s sold in the US are U/U1 phones with the SnapDragon processor. There is a SnapDragon that is rootable and dual-SIM, the SM-N9600. In China you may not sell a phone that is not rootable. However, that phone is also used in many other countries. It should work with T-Mobile too, BUT there may be some performance limitations because it might not support all of their bands. Verizon won't accept it initially, BUT a lot of people have activated the SIM on an approved phone, and then moved the SIM the SM-N9600 and it works fine. The SM-N9600 supports all of Verizon's LTE bands. The downside is you cannot use Samsung Pay, the best pay system out there. The SM-N9600 is in demand which affects the price. It is a good world phone with SnapDragon/Qualcomm and a well implemented Dual SIM. You may see it said that the SM-N9600 doesn't work on a CDMA network. That may be, but Verizon has hardly any CDMA left themselves because the FCC is kicking them off it. They won't have any by year end and were supposed to be and almost were by year-end last year. There is more to the game than GSM vs. CDMA. It is also support for the major specific band for the carrier that is used to log you into their network, which is independent of which band you will communicate on. That is a potential show stopper. About the only place in the world where the SM-N9600 has any issues is in the US. If you can get your carrier to work with it, you are pretty much golden for the rest of the world.

It's really a great phone. Good quality overall and absolutely stable. Battery needs recharging after two days (in my case; calling, surfing, reading / writing e-mails, etc.).

However, the ringing volume is too loud even at the lowest level setting (the volume slider has just a few increments, so you cannot fine-tune the volume). On the other hand, the call volume could be higher.

It does fairly well in good lighting. The depth mapping allows you to refocus while editing in Google Photos, on the device, but not elsewhere. Hopefully other apps with get this ability sometime, too.

Wide angle and Night Sight are disappointing. Looking forward to improvements through software updates.

In the meantime, applied the Gcam port, which works just fine. :)
